Chevrolet GMC Cadillac Front 3 Piece Steering Kit TRQ PSA56265

All right, friends. So, one of the first things we need to do is safely raise and support the vehicle. Once you've done that, you wanna come right upfront to this skid plate right here. Go ahead and remove all 15-millimeter bolts that hold it in. Now, that that's out of the way, let's come right over here to where the idler arm comes down through this arm right here, remove the 21-millimeter nut.

Now, the next thing we would need to do to get this arm out of here, is of course try to drop this sway bar out of the way. If your bolts look like ours do, and you think that they're gonna be an issue, I would just skip right past that and we'll come right up here and we'll remove the whole idler unit right here. To get this out of here, we're gonna use a 21-millimeter right there, and then we'll use a 21-millimeter wrench on the nut side.

Let's put a nice piece of wood in between the frame and this bar right here, just to make it so this bar can't go up too far while we hammer on this right there. Now that that's out of there, we can grab right onto this and we'll get it out of the vehicle. Now, when you're replacing your idler arm bracket assembly here, you're gonna have to remove it from the idler arm. To do that, you'd remove this nut right there, and then you'd do something as simple as a pickle fork coming in between here, or you could even use a puller to separate the two. Odds are, if your idler arm bracket assembly is no good, more than likely at the joint at the idler arm itself is no good as well. In which case I would just replace the both as a pair, that's much easier that way as you can tell. But for the purpose of this video, I'll still show you how to get them apart.

Now to remove this, I like to have it nice and level on the ground and I'll put my foot on it. I'm gonna have it so it's facing down towards the left, so when I remove this and it tries to spin, you can't go anywhere. I'm just gonna use this pickle fork right here, put it right in between the joint, and then give it a couple of loving bonks with my hammer. As you can tell, the two separated at this point, this joint is no good, but that's okay, we're replacing this anyway.

The next thing I like to do is put the unit right inside of a vise if you have access to one. You wanna grab onto this boot, take a look underneath there, make sure there's plenty of grease, go ahead and push it down, that feels great. Now we're gonna take that idler arm, set it right down on there. Take our brand new nut. You always wanna use a brand new nut, okay. So, now if I use my 24-millimeter wrench and I try to tighten this, what you're probably gonna notice is the stud on the inside is gonna start spinning once it gets to a certain point. Okay, so as you can see, it's spinning the stud. Is the nut all the way down? No it's not. So, now we're gonna use a hex bit and you wanna use an 8-millimeter. Come right inside there, that's gonna hold it and now we'll continue tightening this. Make sure it's nice and tight. That feels great.

It may be time to get our unit back up inside the vehicle here, spring it right up and in. Behind those lines, hopefully. Get that in the center link. Let's get this into its bracket. Okay, that looks decent, let's grab our two bolts. Make sure that they have washers, there right through. The other one, here we are. Let's grab the washers and the nuts for the other side. Now let's snug these up. Now let's go ahead and torque these down to 73 foot-pounds

Torqued. Let's get this nut on there. Snug it up, torque this to 46 foot-pounds. Torqued and use our locking cotter pin, slide it right on through there. And then make sure you pin it over, so there's no way this nut can come loose. Get this out of here. Awesome. Let's get this shield back up on here on, I'm gonna line up those holes. Start in all the bolts, before I tighten any of them down. Perfect. The next thing that I would wanna do, is make sure that I get it down to a reputable alignment shop.

All right, friends, so one of the first things we need to do is safely raise and support the vehicle. Once you've done that, you want to come right up front to this skid plate right here. Go ahead and remove all 15-millimeter bolts that hold it in. Now that that's out of the way, let's come right over here to where the idler arm comes down through this arm right here. Remove the 21-millimeter nut.

Now, the next thing we would need to do to get this arm out of here is, of course, try to drop this sway bar out of the way. If your bolts look like ours do, and you think that they're going to be an issue, I would just skip right past that, and we'll come right up here, and we'll remove the whole idler unit right here. To get this out of here, we're going to use a 21-millimeter right there, and then we'll use a 21-millimeter wrench on the nut side.

Right there. Let's put a nice piece of wood in between the frame and this bar right here just to make it so this bar can't go up too far while we hammer on this right there. Now that that's out of there, we can grab right onto this, and we'll get it out of the vehicle. Now, when you're replacing the idler arm here, you're going to need to separate it from the idler arm bracket assembly. When you go to do that, you're going to remove this nut right here, and then you're going to have to try to get something in between to try to separate.

You could try to use a puller, and that would probably be helpful if you have that tool. If you don't have the tool, and you try using a pickle fork, you're probably going to damage this right here, in which case, you would replace the pair, which is what we're going to do today. But I'll still show you how to get it apart anyways just in case you're doing only one piece.

Now, to remove this, I like to have it nice and level on the ground, and I'll put my foot on it. I'm going to have it so it's facing down towards the left, so when I remove this and it tries to spin, it can't go anywhere. Now, that we have the nut off of there, we need to separate the idler arm from the bracket assembly itself. We want to do that without damaging the bracket assembly because we're going to be reusing it, right?

So if you were to look right up here, you're going to see that there's a hole right inside the center of this. What I would like to do is take a punch. I'm going to put this on something sturdy. You can use something like a piece of wood like I have now, a desk, a vise, anything you want. Just be super careful. Come right in here with your punch and a hammer. Let's see if we can get this to come out.

Okay. So that came out, and we caused no damage to this. Perfect. The next thing I like to do is put the unit right inside of a vise if you have access to one. You want to grab on to this boot. Take a look underneath there. Make sure there's plenty of grease. Go ahead and push it down. That feels great. Now, we're going to take that idler arm. Set it right down on there. Take our brand-new nut. You always want to use a brand-new nut.

Okay. So now if I use my 24-millimeter wrench, and I try to tighten this, what you're probably going to notice is the stud on the inside is going to start spinning once it gets to a certain point. Okay. So as you can see, it's spinning the stud. Is the nut all the way down? No, it's not. So now we're going to use a hex bit, and you want to use an 8-millimeter. Come right inside there. That's going to hold it, and now we'll continue tightening this.

Make sure it's nice and tight. That feels great. Maybe time to get our unit back up inside the vehicle here. Just bring it right up and in behind those lines hopefully. Okay, get that in the center link. Let's get this into its bracket. Okay, that looks decent. Let's grab our two bolts. Make sure that they have washers. Put that right through. The other one. There we are. Let's grab the washers and the nuts for the other side. Now, let's snug these up. Now, let's go ahead and torque these down to 73 foot-pounds.

Torqued. Let's get this nut on there. Snug it up. Torque this to 46 foot-pounds. Torqued. And use our locking cotter pin. Slide it right on through there, and then make sure you pin it over so there's no way this nut can come loose. This out of here. Awesome. Let's get this shield back up on here. I'm going to line up those holes. Start in all the bolts before I tighten any of them down. Perfect. The next thing that I would want to do is make sure that I get it down to a reputable alignment shop.

All right, to find the idler arm on your truck—it's on the passenger side—is to start at the tie rod end and just follow the arm all the way to your inner tie rod and then up to your idler arm. The idler arm is on the passenger side, and it bolts to the frame of the vehicle and to the steering itself. You can watch the play in it by just moving the tire back and forth forcefully with your hand. There shouldn't be any sort of play in between the idler arm and the steering shaft itself. That is actually the problem here. The vehicle failed inspection because there's too much play here. It's actually to a point where it's actually becoming dangerous, because this is actually going to break apart pretty soon. We want to get in here and replace the idler arm.

The first step to removing the idler is removing the cotter pin that holds the nut in place. I think to use a pair of cutters to grab it with. It's usually the easiest thing to do, although I may prove myself wrong. There we go. Then you can also use a pair of locking pliers to pull it from the other side. Then you'll take your 21-millimeter socket with an extension, and I'm using a 1/2 inch ratchet because it's going to be pretty tight, and we'll crack it loose. Luckily it's greasy, so once you crack it loose it usually spins right off.

Ideally, you want to have a puller, which you can get from your local hardware store or auto parts store. You can usually rent them. You'll want to put it on like this. We're using a two jaw puller. It wraps up on both sides of the steering arm, and then the center bolt pushes right on the idler arm. Then in our case it's a 16-millimeter right here, but depending on the puller it could be a different size. At that point, you want to just tighten up your puller until the idler arm breaks free. We're going to be pulling off the idler arm with the idler arm bracket, so we need to take out the lower nut right here and then the upper one right up here.

In New England, we like to spray everything with rust penetrator because we take it off because it just makes life a lot easier. On the front side of the bracket, there's the actually heads of the bolt that we're going to put a socket on. Right here is the lower one. Then up here is the upper one. We're going to use a 21-millimeter with an extension and a little wobble adapter so that we can get on there. It's not the easiest thing to reach, but once you're on there it should stay there. Then on the backside we'll put a wrench to hold the nut in place, and hopefully turn it.

Now we're heading for the top bolt on the idler arm bracket. We have our 21-millimeter wrench on the backside and then 21-millimeter socket and extension on the front. At this point, we'll be able to just pull the whole idler arm and its bracket right out of the truck like so. With the idler arm off the truck, we put it in a vice, and you can see how much movement there is in it. There obviously shouldn't be any. That should be nice and tight.

We've cleaned up our idler arm and idler arm bracket. Both are well used, but we're going to show you how to separate the idler arm from the bracket itself. In our case, there's a 24-millimeter nut on here. That may differ depending on if your car has an original OEM part or if it's been replaced before. In our case, it's 24-millimeter. We're going to throw it in the vice and put our 24 millimeter socket on with a 1/2 inch ratchet because you want plenty or torque, and hopefully we can crack this loose. With the nut off, now we have to pull the idler arm off the idler arm bracket.

Once again I'm going to reposition this in the vice. Get a puller, which you can rent from a local hardware store or an auto parts store, or they're actually not too expensive if you just buy them and you think you might be doing this more than once. It might be worth buying a kit to do this. Then you'll tighten down the center bolt. In our case, we have a 16-millimeter on the top of the puller, which we will once again use our 1/2 inch ratchet to tighten up. You always want to wear your safety glasses when you're doing these things, safety gloves, because things tend to spring off when you're least expecting it, kind of like that. Now that it's broken loose, you can pull it right off.

Here are the idler arms. You can see the old one right here. This one has a ton of play in this section. I think it's probably due to the fact that somebody didn't grease this on a regular basis. Usually, if you put the grease in and then forget about it for the next 100,000 miles, it's going to wear out the inside, and you're going to need to replace the whole thing again. This one obviously comes with a new greaseable fitting on the top. The key is you just want to make sure that you properly grease these on a regular basis, and it'll pretty much last as long as you take care of it. It also does come with a little foam piece on the bottom like the original has. Yeah, it looks, feels, and acts just like the original.

In our case, we're going to be replacing the idler arm bracket and the idler arm, and this is the same process, whether you're replacing one or the other, but we always recommend doing them both at the same time since you have them both out of the vehicle. It's just a really easy thing and it doesn't cost a whole lot more, or a whole lot more money to swap them both at the same time. To do this, we'll hook the idler arm bracket into the vice and we'll slide the idler arm right onto the bracket. Put the nut on there. This happens to be a 24-millimeter. Depending on what kind of part you have in your car, it may vary. The size may vary a little bit.

At this point, we can tighten this up. We started tightening the nut, and we found that the whole thing was spinning, like you can see here. That's why they put a hex on the top of this, so that you can put a wrench here and a wrench on the bottom, and then you can tighten down the nut much easier. While the idler arm bracket and idler arm are out of the vehicle, we're going to put the grease in them. That way it's a little bit easier on us once they're installed. Now we can slide the whole assembly right back in. There's one bolt in place. Now we'll do the lower bolt, which is a little trickier.

All right, with the top, or with the idler arm bracket bolts in place, then you can push the idler arm into the steering and tighten up the castle nut, or hand tighten the castle nut. Now we're going to take our 21-millimeter socket and extension and place it on the upper bolt and put a wrench on the backside. Of course, we want to turn the ratchet in the proper direction, and we'll start tightening up that bolt. All right, then we'll go for the lower one, which again 21-millimeter with a ratchet and extension and 21-millimeter on the back.

Now we have the 21-millimeter idler arm nut that we are going to use a ratchet and extension and socket on. We want to get it tight enough so that it is held in place, but we also want to line up the castle nut with the hole in the idler arm so that we can get the cotter pin through. Now you can slide the cotter pin through the hole and bend it over so that it stays in place. Now you'll see that when we move the wheels back and forth, the play between the idler arm and the steering bracket no longer exists.

You want to keep in mind when you're doing this job, after you're done, you're gonna want to go to a local garage and have the vehicle aligned so you don't have premature tire wear.

Just take this cover off. Use a 15-millimeter socket. There's two bolts in the bottom, two on top. Sometimes there'll be a third. Slide it off. Take this cotter pin out. Just use some side cutters and pull that up. Just gonna use a little rust penetrant. It's a little rusty. Take a 21-millimeter socket. Take this nut off.

Now, I want to separate the idler arm from the steering bar. I'm just gonna use a front-end tool. There's many different tools you could use to get this off. Just tighten this up. Put the nut on just so my tool doesn't slip off the stud. It's just gonna use it as a guide.

Another way you can try to do this is use a pickle fork. There we go. Slide that up. I'm going to take these two bolts out. I'm going to use a wrench, a 21-millimeter wrench backside to hold the nut. Use a 21-millimeter socket on the bolt. Take both of those out. Pull the bolts out. Let me just grab the whole idler arm assembly and you just slide it off.

If you're gonna replace just the arm or just the assembly, you're gonna have to separate it. So use a 24-millimeter socket. It helps to put it in a vise and then you can use a puller and separate these two just like that. And take the arm, put the new nut on. Just snug that up tight. All right, just line this up.

I'm gonna have to tap this in place. That's good. Before you put the bolts through up top, just make sure it's going through this bar right here. Put the bolts in, take the two nuts. Get them on the back side. Now, snug these up. Torque to 74 foot-pounds. And take the castle nut, install that there, tighten it up and torque this to 46 foot-pounds.

If the hole didn't line up, you can just tighten it up a little bit more so you can put the cotter pin in. Slide the cotter pin in, and just bend one of the tabs over and trim the excess. Take this shield, install it bolts, put the back in, and tighten these up.

You wanna keep in mind, when you're doing this job, after you're done, you're gonna wanna go to a local garage and have the vehicle aligned so you don't have premature tire wear.

Disconnect the battery. Disconnect the negative terminal. Use an 8-millimeter wrench. Disconnect that, just slide it out of the way.

You wanna make sure the steering wheel is centered, and you want to lock the steering wheel somehow. What you can do is take the seat belt and just go through the steering wheel and then buckle the seat belt. That way, it'll keep the steering wheel from turning.

All right, take the wheel off. We wanna remove the hubcap. Use a straight-blade screwdriver, slide that off. Use a 22-millimeter socket, take the lug nuts off. Remove the wheel.

I'm gonna take this panel off, use a 15-millimeter socket, take these bolts out. There's four bolts. Slide that down.

Take this cotter pin off. Just use some side cutters. Now, remove this nut. Use a 21-millimeter socket. So, now you can try to use different types of tools to separate this. I'm just gonna use a puller. You can try something like this or you can try something like a pickle fork to try to get it in there.

I'm gonna try to use a pickle fork now. Here we go. We're gonna pull this power steering hose off the steering box right here. You may have a clamp that's holding it on, this one happens to have a worm clamp. Use a 7-millimeter socket. If you have the regular style clamp, just use some pliers. You might wanna put a drain bucket underneath because you're gonna lose some fluid. Take that off.

Now I wanna take this steering line off, use an 18-millimeter wrench. It's not easy to get in there with a wrench. If you have a crows foot, that would work a little better. But just do the best you can.

So, our line is rusted at the top of the steering box and it's not breaking free. In our situation, I'm gonna have to take it off the brake booster. I'm gonna use a 16-millimeter wrench and loosen this up. But, ideally, if you can get it off the top of the box, steering box, then that would be ideal. And I can slide this line out from here. Now I'll just take this line out with the steering box. Just like that. And then, on the top of the steering box, we need to take the linkage that connects this to the lower steering column. There's an 11-millimeter bolt, take that out. Pull that bolt out. It's a good idea to replace this bolt whenever you take it out.

Let's just take a pry bar, get in between the lower steering shaft and your steering box and just pry it up to try to separate the two.

So, I'm gonna try to get this off the rest of the way from underneath. Take your pry bar, try to get in between that groove right there. Just try to hammer it up. All right, that's popped off. It's good.

Now we need to take these three bolts out. There's one behind the shields right there. Use a 21-millimeter socket. Take these out. All right, I'm gonna take the last one out. Just loosen those so they're loose like that.

[inaudible 00:04:53] steering box, just lift it up because you gotta pull that pitman arm out. Twist it sideways so we still have that line connected. And here we go.

Now I'm gonna use a 34-millimeter socket to take this nut off. Take that off. Now this is a dust seal right here. Just get a straight-blade screwdriver and just push it up. Just get that out of the way so we can put our tool on and put the pitman-arm remover on. Here we go.

Now there is four key ways for this to line up. So, install this the same way that the old one came off. Put the lock washer on, put the nut on, and tighten this up. And then do the best you can, put this in a vise and then torque this nut to 180 foot-pounds.

And then slide this dust boot back down. Just like that. Looks good.

Now I'm gonna send the hose up first. You know, if you were able to not have to have the hose connected, then you don't have to do this part. And slide the box in position. You wanna get the pitman arm through that steering bar...just like that. Make sure that's lined up first. Move this around a little bit and get one of these bolts started. And you can try to get the other one started as well. I'm gonna have to rotate this a little bit.

Now I'm gonna torque these bolts to 110 foot-pounds. Now put this nut on. And we're gonna torque this nut to 46 foot-pounds.

Now if the hole's not lined up for the cotter pin, you can tighten the nut a little bit more. It's better to tighten it than loosen it. And that looks good. A little more. Put the cotter pin in. Take some side cutters and just bend it...just like this. And trim the excess.

So, you just wanna make sure that the steering box, the wheels are straight just like it was when you took this shaft off. And just get this lined up. You can get it started while you're underneath. Or you can try to do it from up top.

All right, let's slide the steering shaft onto the box, or the gear. That's lined up. Now you put that bolt in. And do the best you can with torquing this, it might be a little bit better to torque this from underneath. You could get directly on it. You wanna torque that bolt to 37 foot-pounds. Okay, good.

Now I'm gonna run this hose back the way it came, up to the booster. And if you didn't take it off here, connect that hose down below.

All right, now snug this up. Now, if you have the ability to use a torque wrench, you can torque this nut, or the lower nut, on the steering box, to 20 foot-pounds. That's good.

Now install this hose. It goes to the cooler. And tighten this up, if you have a worm clamp, or use the hose clamp pliers. And just snug it up. And this cover, bolt's in. And tighten thee bolts down.

Now let's reconnect the battery. Give it a wiggle, make sure it's tight, and you're good to go.

Now we're gonna top off the fluid, take the cap off of the power steering pump. And then use a funnel, and check your owners manual, put in the appropriate fluid.

All right, so, I over filled this a little bit, which is okay. Now, with the front wheels off the ground and the cap off, you might still wanna put a bucket underneath. I'm gonna turn the wheel back and forth about 20 times. Slowly.

All right, we're gonna double check our fluid level. I haven't started the vehicle yet. And the fluid level's right there. Before I just suck some of the fluid out of there, I'm actually gonna start the vehicle, turn the wheel back and forth a couple times, and then recheck it and adjust accordingly.

Install the tire. Put the lug nuts on. All right, tighten these lug nuts down. I'm going to tighten them in a star pattern, or a cross pattern, to 140 foot-pounds to tighten the wheel down evenly. I'm just go around again, double-check. Take the center cap.

Normally, there is a shield right here, you wanna take that shield off. There'll be four or five 15-millimeter bolts. Take that off, get it out of your way. Now, we're gonna take this nut off. On this vehicle, there's a cotter pin. So, I'll just use some side cutters, take this cotter pin off. Just bend it back a little bit and just pry it out. And sometimes they break. There we go. Now, I'm gonna take a 22-millimeter socket, take this nut off. Now, I wanna remove that stud from the steering linkage that goes through the idler arm. I'm gonna use a tool like this, it's gonna press it out. You can use a couple other methods. You could use a pickle fork, try to get it out this way...that way. Just gonna put the nut on to stabilize the tool so it doesn't fall off. All right. While that's on there tight, I'm just gonna give it a tap with the air hammer, see if the vibrations loosen it up. So, that didn't work out. So, I'm gonna try a pickle fork. Sometimes these are tricky to get to separate. There we go.

Now, I'm gonna take these two bolts out. I'm gonna use a 21-millimeter wrench. On the backside, there's a nut and then a 21-millimeter socket on the front. Get that nut off. Take the bolt out. And just grab the idler arm and the housing and just slide it up. If you were gonna replace one of these pieces or the other, you can separate that nut. Just gonna put the housing in the vise, make it easier to install. Take the nut off. All right. Take the idler arm, put the nut on, take a 24-millimeter socket and snug it up. Now, I'm gonna take this castle nut off. And get this in position. As you slide the housing in the bracket, you wanna make sure the idler arm goes through the steering linkage. Get the bolts lined up. And put the nuts on the backside. Now, I'll tighten these down. Then torque both of those bolts to 73 foot-pounds. Now, install the castle nut and tighten that up. And then torque this to 46 foot-pounds. And find the hole through the stud and you can use the cotter pin, slide it through. If it doesn't fit or if you can't get it to line up, you can tighten the nut up a little more so it does line up. There we go. And use some side cutters and just bend this like this. And then you can trim the excess. Now, if you have that shield right here, reinstall that shield.

You wanna keep in mind when you're doing this job, after you're done, you're gonna wanna go to a local garage and have the vehicle aligned so you don't have premature tire wear.

Just take this cover off. Use a 15-millimeter socket. There's two bolts on the bottom, two on top, sometimes there'll be a third. Slide it off. Take this cotter pin out. Just use some side cutters. And pull that out. Just gonna use a little rust penetrant, it's a little rusty. Take a 21-millimeter socket, take this nut off. Now I wanna separate the idler arm from the steering bar. I'm just gonna use a front-end [SP] tool. There's many different tools you could use to get this off. Just tighten this up. Put the nut on just so my tool doesn't slip off the stud. Just gonna use it as a guide. Another way you could try do this is use the pickle fork. There we go. Slide that out.

Gonna take these two bolts out. I'm gonna use a wrench, a 21-millimeter wrench backside to hold the nut. Use a 21-millimeter socket on the bolt. Take both of those out. Pull the bolts out. Just grab the whole idler arm assembly and just slide it out.

If you're gonna replace just the arm or just the assembly, you're gonna have to separate it. So use a 24-millimeter socket. It helps to put it in a vise. And then you can use a puller and separate these two. Just like that. And take the arm, put the new nut on. Just snug that up tight.

All right, just line this up. Gonna have to tap this in place. It's good.

Before you put the bolts through up top, just make sure it's going through this bar right here. We'll put the bolts in. Take the two nuts, get them on the backside. Now snug these up. Torque these bolts to 74-foot-pounds. And take the castle nut, install that there. Tighten it up. Then torque this to 46-foot-pounds. If the hole didn't line up you can just tighten it up a little bit more so you can put the cotter pin in. Slide the cotter pin in. And just bend one of the tabs over. And trim the excess. Take the shield, install it. Put the bolts back in. And tighten these up.

You can replace the idler arm bracket by itself. To find the idler arm on your truck, in this case it's on the passenger side, but another easy way is to start at the tie rod end and just follow the arm all the way to your inner tie rod, and then up to your idler arm.

The first step to removing the idler is to remove the cotter pin that holds the castle nut in place. I like to use a pair of cutters to grab it with. It's usually the easiest thing to do, although I may prove myself wrong. There we go. And then you can also use a pair of locking pliers to pull it from the other side. Then you'll take your 21mm socket with an extension, and I'm using a 1/2" ratchet, because it's going to be pretty tight, and we'll crack it loose.

Luckily it's greasy, so once you crack it loose, it usually spins right off. So, ideally you want to have a puller, which you can get from your local hardware store or auto part store. You can usually rent them. And you'll want to put it on like this. We're using a two jaw puller. It wraps up on both sides of the steering arm, and then the center bolt pushes right on the idler arm. Then, in our case, it's a 16mm right here, but depending on the puller, it could be a different size. And at that point, you want to just tighten up your puller until the idler arm breaks free. We're going to be pulling off the idler arm with the idler arm bracket, so we need to take out the lower nut right here, and then the upper one right up here.

In New England we like to spray everything with rust penetrant before we take it off, because it just makes life a lot easier. On the front side of the bracket, there's the actual heads of the bolt that we're going to put a socket on. Right here's the lower one, and then up here's the upper one. So, we're going to use a 21mm with an extension, and a little wobble adapter so that we can get on there. It's not the easiest thing to reach, but once you're on there, it should stay there. And then on the back side, we put a wrench to hold the nut in place, and hopefully turn it.

Now we're heading for the top bolt on the idler arm bracket. We have our 21mm wrench on the back side, and then 21mm socket and extension on the front. At this point, we'll be able to just pull the whole idler arm, and its bracket, right out of the truck.

We've cleaned up our idler arm and idler arm bracket. Both are well used. But we're going to show you how to separate the idler arm from the bracket itself. In our case, there's a 24mm nut on here. That may differ depending on if your car has a original OEM part or if it's been replaced before. In our case, it's 24mm. So we're going to throw it in the vise, and put our 24mm socket on with a 1/2" ratchet -- because you want plenty of torque -- and hopefully we can crack this loose. With the nut off, now we have to pull the idler arm off the idler arm bracket.

So once again, I'm going to reposition this in the vise. Get a puller, which you can rent from a local hardware store, or an auto parts store, or they're actually not too expensive if you just buy them and you think you might be doing this more than once. It might be worth buying a kit to do this. And then you'll tighten down the center bolt. In our case, we have a 16mm on the top of the puller, which we will, once again, use our 1/2" ratchet to tighten up. So, you always want to wear your safety glasses when you're doing these things, safety gloves, because things tend to spring off when you're least expecting it. Kind of like that. So now that it's broken loose, you can pull it right off.

Here you can see the old idler arm bracket and the new idler arm bracket. You can see, the old one is really easy to turn. That's how you know it's worn out, because the insides of it are actually worn out. My guess is that somebody didn't grease this appropriately on a regular basis, and that's something that you need to do if you want to keep these things to lasting a long time. The new one is nice and tight like it should be, and we'll obviously grease this when we install it on the car, and then keep up with the greasing.

You know, probably every oil change we'll put some grease in this and make sure it stays in good shape for a long time. You can see that the mounting brackets are exactly the same. You can line them up, they fit the same. It comes with a new seal on the end, and of course, a new nut. In our case, we're going to be replacing the idler arm bracket and the idler arm. And this is the same process, whether you're replacing one or the other, but we always recommend doing them both at the same time since you have them both out of the vehicle. It's just a really easy thing, and it doesn't cost a whole lot more money to swap them both at the same time.

So to do this, we'll put the idler arm bracket into the vise, and we'll slide the idler arm right onto the bracket. Put the nut on there. This happens to be a 24mm. Depending on what kind of part you have in your car, it may vary. The size may vary a little bit. And at this point, we can tighten this up. So we started tightening the nut, and we found that the whole thing was spinning, like you can see here. So that's why they put a hex on top of this, so that you can put a wrench here and a wrench on the bottom, and then you can tighten down the nut much easier.

While the idler arm bracket and idler arm are out of the vehicle, we're going to put the grease in them, that way it's a little bit easier on us once they're installed. Now we can slide the whole assembly right back in. There's one bolt in place. Now we'll do the lower bolt, which is a little trickier. All right. With the top ... or, with the idler arm bracket bolts in place, then you can push the idler arm into the steering, and tighten up the castle nut, or hand tighten the castle nut. Now we're going to take our 21mm socket and extension and place it on the upper bolt. Put a wrench on the back side. Of course, we want to turn the ratchet in the proper direction, then we'll start tightening up that bolt. And then we'll go for the lower one, which again, 21mm with a ratchet and extension, and a 21mm on the back. And now we have the 21mm idler arm nut that we are going to use a ratchet and extension and socket on.

We want to get it tight enough so that it is held in place, but we also want to line up the castle nut with the hole in the idler arm, so that we can get the cotter pin through. And now you can slide the cotter pin through the hole, and bend it over so that it stays in place.
