Before you jack up the vehicle, you want to crack all of these lug nuts loose because that way the wheel won't spin when you're trying to turn the lug nuts. You can use the 22-millimeter socket to do this or if you want to use the lug nut wrench that comes with the car and the spare tire kit, you can use that as well. You can use a jack and jack stands to lift the vehicle in a driveway situation or a garage, but we have a lift to make the video shooting a little bit easier. So we're going to go ahead and raise it up on the lift. Now the vehicle's off the ground, we can remove the rest of the lug nuts. It's easy to use a 22-millimeter deep socket to reach in there and spin them out. Now we can pull the wheel off of the vehicle just like this.
Right on the back side of the knuckle is the ABS sensor, so we're going to put a 10-millimeter socket on it to crack that loose. You can pull the bolt right out just like that. Then with the bolt out, you should be able to just pull the sensor right out of the knuckle just like that.
Now we're going to unclip the ABS sensor wires with a pick. You should be able to just the pick in here and open it up. Same thing with this one and then this one, and we'll pop them out of the little clips. All right, and now we can come up here in the back and we can get the 10-millimeter nut off to remove the bracket. I'll use a 10-millimeter socket, and I like extensions but you don't have to use an extension on this. Then just pull the nut right off, and at that point, the bracket will come loose and so will the ABS wire. Right behind the splash shield is the connector for this, and if you just push down the tab, you can pull the connector right out and free your ABS sensor. At this point, you can pull the ABS sensor right out of the vehicle like that.
Installing the ABS sensor is very similar. You can come over here and slide the ABS sensor into the hole in the knuckle and then on the other side you can slide the rubber grommets into the little brackets that they live in like that and here's the third one. Then you can just push them closed. We have the ABS bracket, which goes on just like that. We'll spin the nut on by hand, and then we can tighten it up with a 10-millimeter socket and a ratchet. I'm using a quarter drive ratchet. That way we don't put too much force on it. Right behind the splash shields is the connector that you'll connect it into, so all you do is push it right up into the connector and you'll hear it snap into place.
On the ABS sensor itself, there is a 10-millimeter screw that needs to be put back in, so we'll put it in by hand first. That way we don't cross-thread anything, and then you can use your quarter drive ratchet and your 10-millimeter to tighten it down. There we are. Now we can put the wheel back on. Just line up the lug nuts, and then you can hand-tighten the lug nuts. With all of the lug nuts hand tight then you can put your ratchet on it and we're just going to snug them up as best we can with the vehicle in the air, and then we'll get it on the ground and tighten it up. Now we'll lower the vehicle right back down to the ground. Now we're going to torque the lug nuts to 125 foot-pounds. Then we'll do it in a cross pattern.
