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 show you how to replace a front hub on this 2003 GMC Envoy XL. The items that you'll need for this is a new hub from 1AAuto.com, a 17mm, 18mm, 19mm and 35mm socket and ratchet, a piece of pipe for extra leverage, 18mm wrench, flat blade screwdriver, torque wrench, hammer, and jack and jack stands.
Start off by prying off your hub cap. Then just loosen up this 35mm nut. Now loosen the lug nuts in a crossing pattern. We'll just fast-forward as Mike does this. Once you've loosened them, just jack the vehicle up, and then remove the lug nuts the rest of the way. Now the wheel will pull off.
Now, you want to remove these two 17mm bolts, and you can see Mike's using an 18mm wrench to hold the nut on the inside. That'll just make it easier to remove that bolt. Now, using a flat blade screwdriver, just pry out on the caliper. Then you can just set that aside.
Now pry out your brake pads. Now, you want to remove these two 18mm bolts. We'll just fast-forward as Mike does that, and you can see he's using a piece of pipe for some extra leverage to help break those bolts free. Remove the bolts the rest of the way, and then the caliper bracket comes off. Now, you need to remove your rotor, and hopefully you can just use a hammer, tap on the rotor a little bit, and it will come off. Our vehicle has some corrosion, so we end up using the alternate method.
If you have trouble getting the rotor off, it actually has press holes. You would get a bolt that's the proper size, I believe this an M12 bolt, and you use two bolts, thread them into those holes, and as you tighten them up, they press against the hub and push the rotor off. Once you've removed the rotor, if you haven't already, remove the center hub nut the rest of the way. Give the axle a good firm hit with a hammer, and once you see it's moving, then you know it's free.
Next, you want to disconnect these clips along this harness. To do that, you just flip those open with a flat blade screwdriver, or you can just pry them out. First, pull the harness connection out from the car, and then push the tab and disconnect the harness. We'll just fast-forward as Mike pries out those clips. Just note, that we did just unclip the harness that is connected to the upper control arm and left it in place. Now, just remove these three 18mm bolts that hold in the hub.
First, we're just going to spray the other side with some penetrating oil to help remove them. We'll fast-forward as Mike removes these. It does help to turn the wheels so you have better access to whichever one you're working on at whatever time. Now, using a hammer, just hit the back of the hub to loosen it, and then just slide it off the axle, making sure your harness is pulled through. Then just hammer that backing plate off the hub and pull your harness up and out of the plate.
On the left is the old hub; on the right is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. Take your backing plate and feed the harness of your new hub through it. Then put the backing plate into place on the wheel knuckle. You want to make sure that the harness is going up through that top part of the plate. Once you have that lined up, push the hub back onto the axle and into place.
Once it's in place take a bolt and just twist in to hold the plate and hub to the wheel knuckle. Then just replace the other two bolts, and tighten all three of them up. Now, torque each of these to 90 foot-pounds. We left some clips in the body of the car, so you just remove the ones you don't need from your new harness, and the ones you do need just leave on there and push into place on the wheel knuckle. We'll just fast-forward as Mike re-clips the harness all the way along.
Then reconnect the harness. You want to make sure these holes line up in between the two holes that are on the hub, and then you just slide your rotor back into place, and replace a lug nut to hold it into place. You want to check these slides on your caliper bracket, and make sure they're greased up. If they're not, just apply some brake grease to them. Then fit the bracket into place and then just start twisting your bolts by hand and then tighten them up. Torque each of these to 110 foot-pounds. Then just replace your brake pads, and if there's no grease on the ends, just apply some brake grease.
Now, push your caliper back down into place and replace those two 17mm bolts. We'll fast-forward as Mike does that and tightens those up. Now torque each of those to 40 foot-pounds. Replace the hub nut. Remove the lug nut that you put on there to hold the rotor in place.
Put your wheel in place. Then replace each of the lug nuts and tighten them preliminarily. If you're working with air tools, you can tighten up the center nut preliminarily or you can wait and do this on the ground. Now torque each of these to 100 foot-pounds in a crossing pattern. Then torque the hub nut to 103 foot pounds. Then replace your hub cap.
After you've done any work on the brakes, you want to just pump the brake pedal until it firms up. Then you want to do a stopping test from five miles per hour and then 10 miles per hour.
