Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to replace an upper control arm and ball joint assembly on this 2011 Chevy Silverado. This is a 1500 4-Wheel Drive; this procedure is the same for any 2007 to 2013 Silverado and Sierra 1500. The passenger side is basically the same as the driver's side.
You'll need a new control arm from 1A Auto.com, jack and jackstands, 10 to 22mm sockets with a ratchet and extension, an 18mm wrench, and an additional wrench for some extra leverage, breaker bar or pipe for extra leverage, penetrating oil, hammer, pry bar, and a torque wrench.
From the top, there are three 18mm nuts that hold the top of the strut in place: you see one there; one has a wire loom on it there that I'm going to reach down and grab, and just pull off. Apologies for the camera shot, but you just grab the wire clip and pull it up off the stud. Okay, so you have your other one there, and your third one, there. Now, use an 18mm socket with a long extension, and remove those three nuts. Remove the center cap just by prying with a screwdriver, and if you don't have the benefit of air tools, loosen the lug nuts with the vehicle on the ground, then raise and secure the vehicle, and then remove the lug nuts the rest of the way ... remove the wheel and tire, and they are 22mm lug nuts. Turn the wheel using hands, or use the steering wheel, and then you need to remove the stabilizer link; make sure you put some penetrating oil on the top end of it there, then use a wrench on the top side, and a socket wrench on the bottom side, and remove it all the way. I'm going to speed up here a little bit; we "cheat" a little bit by just using an impact wrench to take that off. That just speeds things up for us. Then, we'll remove the bolt the rest of the way: push down on the suspension, and pull the link out of there.
Up underneath, there are two 15mm bolts; hold the bottom of the shock strut in place. I was just using a 15mm socket and ratchet; you might want a breaker bar to break them loose, but they come apart pretty easy on this truck, and we'll fast forward as we just take those out. Take those bolts out, press down on the suspension some, and bring the strut down, and then up and out.
Now with some penetrating oil, spray down the ends of the two bolts that hold the control arm to the frame. There are little tabs that come out of the frame and go through these washers; and I'm using a paint marker to mark on the washers where those tabs are, so that when we re-assemble this, we can give it a good preliminary alignment. You will want to re-align your truck after you do this repair, but this at least gets it somewhere close to where it was originally. An 18mm nut holds the ball joint to the steering knuckle; put an 18mm wrench on there, and then hook another wrench onto it for extra leverage. Loosen it up. Here, you can see we still have the nut on the ball joint; we're going to put a big pry bar in there; pry between the steering knuckle and the ball joint, and hit the steering knuckle with a hammer until it pops apart.
There's a 10mm bolt on top of the control arm that holds the clip that holds the wire harness: remove that. Now, we're going to support the suspension with a jack. Remove the nuts that are on the end of the bolts that go into the frame; it's a 21mm socket with a ratchet, and we use a pipe for some extra leverage to get the bolts going and once we have them going, they come off easier than just with the ratchet, and I'll fast forward as we finish that up, and do the other side. As you see, here, use a hammer to start driving those bolts out, and then you can work them out by hand. You may have to use a punch and drive them further through. Now, remove the nut the rest of the way off of the top ball joint there, and then you should be able to pull the control arm up and then pull it out; you might need to use a crowbar or a large screwdriver to help pry it out.
The ball joint in our new control arm comes with a grease-able fitting, so we'll install that. Put the new control arm up in place, and you just kind of wiggle it up and down, I guess, to get the bolts to line up preliminarily with the frame. Now, put the bolts back in, get one bolt started in as much as you can, and then actually, if you start the other bolt in on the other side, this kind of lines things up; you should be able to get that bolt most of the way in. Use a hammer to tap it in if you need to, and then go back, and again, if you just move the control arm around a little bit, you should be able to push it in. I'm just going to fast forward as we start the nuts on ... And now, we're putting a wrench on the bolt end, and you can see we just pull it up, and re-align that mark with the tab on the frame, and just preliminarily tighten the nuts up just to hold it in place well. Here, we're just going to let the jack down some. This just relieves a little pressure so that we can then lift the upper control arm up, and get the ball joint lined up and then back into place, and then once it's all set, we'll actually jack the suspension back up until it's basically in the position it should be when the vehicle is riding on the ground.
You put the ball joint nut on, and start tightening it; most likely, it's going to start making the stud on the ball joint spin, and if that happens, you'll see here in a second, you can put a 6mm Allen wrench into the ball joint stud. Hold it; you need to be careful: sometimes as you pull the ball joint stud through, it can interfere with the axle, and you might need to undo the axle nut and push the axle through a little bit in order to get the wrench back out. Make sure you put the wrench on there, and put the second wrench on for some extra leverage, and tighten that nut right up.
Now again, we have the suspension up in the about the same position it's going to be when it rides on the ground; you want to make sure you have it up there, and then torque the bolts for the control arm to 100 foot-pounds, and just make sure that the marks on your washers and everything still line up. Now you can let your jack back down, reinstall the 10mm bolt that holds the wiring harness clip, and use a grease gun to put some grease into the ball joint, and we generally do it until we see the boot between the ball joint and the steering knuckle start to expand. Bring this strut back in: if you look on the top of the strut where the coil spring ends, that goes to the outside, and you put the strut back in, and then lift it up into place, and then you can just start the nuts onto the top. Install all of the lower bolts, and the strut, and tighten them up; you want to tighten them up between 70 and 75 foot-pounds. We speed up as we put the stabilizer link back in place; use a pry bar to lift up on the sway bar a little bit; put the link back in place, put the bolt up through, and then tighten the nut down on top.
The,n put our wheel back on, put the lug nuts back by hand first, then tighten them preliminarily, and with the vehicle back down on the ground and secure, torque the lug nuts to 110 foot-pounds using a crossing pattern. Tighten up and torque the top three nuts to 75 to 80 foot-pounds, and put that wire clip back in place, and you should be all set.

One of the first things you want to do is safely raise and support your vehicle by the frame, so your suspension can hang. Once you've done that, take a small pry bar, and we're going to take off this center cap. If you were to spin it, you're going to see a little notch in the cap. Just carefully slide this off of here. That exposes our 22-millimeter lug nuts. Remove all six. Remove your wheel. Now, to remove our 21-millimeter nut. Let's just put that nut on just a couple threads. Now, we're going to take a hammer, and we're going to hit right here on the knuckle. You want to be very careful for your brake rotor.
Now, that the wheel is off, we have a clear view of where we're going to start working. We're going to disconnect the electrical. This is the ABS right here, and it's very delicate. I'm just going to come right up along here, and you're going to see where it's...well, where it's supposed to be mounted to the frame. Should be pretty secure. This is missing about half of its clip, so I'll make sure I secure it in afterward. This purple right here is a little lock. It's holding it from becoming separated. I like to just come right in between here. Pop that up. Now, we'll separate this. Just take a peek. Make sure you don't see any funny colors. If you were to come right down along here, we're going to get this clip off of here as well. Just give it a little twist. Lift it up. Grab that ABS wire. Carefully set it aside.
The next thing we're going to do is remove this 10-millimeter headed bolt. So, just make sure everything is nice and clear from your upper control arm. We're going to go ahead and take out this nut right here. Let's just go ahead and take that upper ball joint nut, and just start it on there just a couple threads. The next thing we're going to do is come right up here with our pickle fork, which is this tool right here, right up along the top. And then I'm going to use my hammer, and I'm going to separate the ball joint from the knuckle. Just be careful because it will want to pull away, and it could put a tug on your axle. I'm just going to carefully rest this away. If you wanted to, you can secure it with something such as a bungee cord. Okay. Just make sure we have the ABS wire, so it's not getting a tug. It's not putting a tug on the axle in any way. The next thing we're going to do is remove the bolts that go from right here through to the other side. I like to use a 21-millimeter on the inside area, and then you'd use a 21-millimeter on the outer portion as well to remove the nut. Leave that one in like that for now. Do the same to the other side. Let's go ahead and take the bolts out.
Outer. Go ahead grab onto that control arm. There it is, friends. Now, it's a good idea to just make sure that this area of your cam bolts are nice and clean, and then we're just going to hit it with some copper Never-Seez here, and that's going to help the alignment professional down the line.
Now, it's going to be time to install your brand new control arm. One of the first things that you want to do with that control arm is make sure that you have the same shape. As you'll notice, this isn't a perfect V. If you were to see that the slanted end on this side was slanted on the other side for some reason, that means you have the wrong side of the vehicle. Once you know you have the right side, go ahead and put it up in here. Might require a couple light bonks just to kind of get it in there. I like to use a rubber mallet for that. Just get it so it's at least lined up enough to be able to line up the bolt and get it started. Let's go ahead and see if we can get this bolt started in here. Feels like it's starting to want to go in. Just have to try to get the right angle with the control arm. Okay. Before you go ahead and push it in all the way, you need to make sure that you have your adjuster so it's facing up and inside of the groove. We have a little piton that comes out. And usually, when I put these in, I'll get them both started, and then I'll kind of put these back to exactly where I got them from. And then the alignment professional can, of course, align it from there.
Let's go ahead and get this back on there. As you can tell, the originals came with this little plastic in there. You can go ahead and pop that out of there if you want to. I'm going to leave it in though because that's going to tell me exactly where this needs to be when it comes to lining it up. Just turn the bolt side until it lines up where it needs to be. Go ahead and start it on there. We'll do the same to the other side.
Now, before we go ahead and tighten these up, it's important to remember that you don't want your control arm sitting down like this when you tighten it up. Essentially, the way that you want the control arm to be, when it's tight, is as if the vehicle was sitting on the ground right now. With all the weight of the vehicle on this wheel, it would of course be having this sitting almost parallel to the ground, so that's where we're going to go. I'm just going to slide this in there, and now I'll realign everything here, and then we'll snug it up. Okay, that bottomed out. We'll torque it to manufacturer's specifications in one minute. Now, that both of those are snug, we can take this out, and we'll torque these to 140 foot-pounds. So, now we'll just get this, so we can get the upper ball joint stud in here. You're going to want a pry bar, so you can pry down on this. So, I'll grab that real quick. Let's go ahead and pry this down, so we can start the nut in there.
Let's go ahead and bottom this out. Now, the torque for this should be 37 foot-pounds. Obviously, as you can tell by the limited amount of space in between the axle and the nut, we're not going to be able to get a torque wrench in there. Thirty-seven foot-pounds isn't very much just to say. Take a nice long wrench. Put it on there. Give it a couple nice tugs. Once you're sure that it's tight, now you're going to want to take a peek at that stud for the ball joint, and the nut itself, to see if you have a slot lined up with the hole. If you don't, you need to continue tightening, not loosening, until you get to the next hole.
Go ahead and peen over that cotter pin, so it locks in the nut. There's no way that it can loosen up on its own. Let's go ahead and get this little grease fitting in there. Let's go ahead and pump some grease into this. I'm just going to put a little splash of Never-Seez in here. I've got my mounting bolt. Let's use our 10-millimeter and snug it up. Make sure it's fully secured. Make sure there's nothing binding your flex hose for your breaks are not twisted in any way.
Now, it's time to get our ABS wire resecured. Let's go ahead and put it in right here. Make sure it cannot come loose. If this can hang around and move around, it could potentially get damaged. Go ahead and connect this in now. Listen for a click. Give it a tug. Go ahead and slide in your lock. Now, we're going to take our mounting hardware here and just slide it right down in it. It's just a little push clip. Give it a nice tug. Make sure it's definitely secured.
So, of course, next, you'd want to go ahead and torque down this nut right here, and that's going to be torqued to 177 foot-pounds. You can do that several ways. If you were to just do it like this, what you're going to notice is it just keeps spinning. If that was the case, what you would do is you can use a pry bar coming straight through these lug studs like this down to the ground. And so, it holds it from spinning on you, and then you would torque it. If you didn't want to go through the process doing that, you can go ahead and throw the wheel up on there, and then go through the center hole, which is the way that I'm going to do it.
We'll grab those lug nuts. Start them all on there. Let's bottom these out. Now, we'll bring it down to the ground, and we'll make it so the wheel is just barely touching enough, so the wheel can't spin. It's time to torque down this axle nut 177 foot-pounds like I said. Torqued. Now, let's do the lug nuts 140 foot-pounds. Go crisscross. Torqued.
Now, it's going to be time to get the center cover on. Before you go ahead and pound it on there, just take a look at the back. You're going to see something that looks a lot like a valve stem. Line it up. It's going to go pretty much just like this. Light bonk and then, of course, clean up your wheel, make it look nice and pretty, and take it for a road test.
