Hi, I'm Don 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 the rear axle bearing on this 2002 Chevy Suburban. It's the same part and similar process on these Suburbans from 2000 to 2013. The items you'll need are a new axle bearing from 1AAuto.com and this assortment of tools.

Start off by loosening up these lug nut covers. We'll fast forward as Don does this. Once those are all loosened up, you can pull the hub cab free. Now, you want to loosen the lug nuts preliminarily, raise the vehicle and remove them the rest of the way unless you have air powered tools you can do it while it's on the ground. Now, remove these two 12mm bolts. We'll fast forward as Don does that. Now, to loosen up your rotor, either use a C-clamp to squeeze it or a screwdriver through the middle of it and pry between the caliper and the brake disc and that loosens up the caliper so it comes off easier. Now, pry out the brake pads.

Now, remove these two 18mm bolts. Just use a piece of pipe to help break it free. We'll just fast forward as Don removes those two bolts. Now, pull your caliper bracket off. Pull the rotor off.

Now, on the differential cover, there are 10 to 12 bolts and our are pretty rusty so we use a cold chisel to knock the rust off of each side. These should be 13mm bolts if they're in good shape, we actually end up using a half inch socket because the rust has actually reduced their size a little bit. You'll see later we pound a half inch socket on there and are able to get them all off. We'll just fast forward here as Mike removes that bolt the rest of the way. Then, he's just going to repeat the procedure on each of those other bolts, all the way around the differential cover. For the higher ones, it does get a little more difficult and you will need an extension for your socket and ratchet to actually remove those bolts. Make sure you have a drip pan below the differential cover before you remove the last of the bottom bolts. You just want to remove those. Now, using your chisel, just hammer out on the bottom of the differential cover. Then replace the bolt at the top of the differential cover. Then use your chisel and hammer again on the other side and just let the fluid drain out.

After it's drained for a while, just pry out on the bottom and then remove that bolt and then pull the cover down and out. Now, if any debris falls down inside of here, as you can see right there, you just want to vacuum all of it out. Then take a rag, make sure it's somewhat clean and just wipe everything down and just stick this rag back in there. Then using a razor blade just cut off that old gasket along the outside. Then just use a wire brush to get any leftover residue of the gasket.

At this point, you'll probably want to have your vehicle in neutral, and rotate the chuck around, so you can see that 8mm bolt, right there, and remove the 8mm bolt. Then this pin will come down and out. Now, push your axle in, and then, again, you're going to want to have your vehicle in neutral so you can use the drive shaft and rotate the chuck around so you can see into where the C-clamps are. You can see that there's a clip on either side that holds either axle in. What you want to do is just use a stick magnet to pull the clip out on the axle you want to replace. There it is. Then the axle will just pull free.

The only way to pull a bearing is with the proper tool. You can see this one's actually too big because it doesn't even fit in the opening. This one could work but it's small and it'll end up possibly pulling the bearings right out. This one will be just right and basically, you just back this nut off, stick that in there, make sure it catches, and tighten that up. You actually don't even have to pull the seal out; you can do it all with bearing puller. So, just pull it out, tighten this nut up, this helps so stuff just doesn't go flying.

Take your new bearing, angle it right in and you'll want a good size tool. Go right flush on it and drive it straight in. There's a little line right here; it means it's all the way in. You should be able to see that. We just use a little bit of gear oil to somewhat prime the bearings, just make sure you work it all the way around. Then, carefully put the bearing seal back in, tap it straight in.

Then, slide your axle into place. You want to lift it up, careful not to drag it on the seal too much, you don't want to prematurely wear out the seal. Then once it gets in, into the machined area then grab the axle and I'm actually lifting up the inside of the axle where it goes into the carrier bearings on the inside. You just got to find the right spot. Once you do, it goes right in and then just make sure you push it all the way in so you can get the C-clamp on the other side. Now, put the C-clip back in place, you'll have to make sure the axle is pushed in further than it should go and then once you have it in place, you'll want to pull the axle back out and the C-clamp goes into place.

Now, we're using a new differential cover. So, we have a separate gasket, but if you're using your old differential cover, you want to make sure the RTV goes all the way around and that there's no gaps in it and you can see ours does have a gap but because of the other gasket that won't matter. Make sure you circle each bolt hole. Make sure there's no fluid on the outside here. Then take your differential cover and feed it up into place. You just want to replace the top bolt to hold it in. Then we'll just fast forward as he replaces the rest of the bolts. Make sure for this top bolt that you put this harness back into place then let the gasket sit for a minute if you used RTV and then tighten each of those bolts up. Then you just want to torque each of these to 15 foot-pounds in a crossing pattern.

Now, remove this filler plug, using your 3/8 ratchet and ours is in rough condition so we're just going to hammer the ratchet into place and then just remove that plug. Now, replace the differential fluid and you want to just do this until it starts to pour over the side. When it starts to pour over the side, you can just put your pinky in there and make sure that the fluid is right to the top of the filler hole. If it is then you are all set. It's all the way up there. You can replace your cap. Now, jut tighten it up with your ratchet and you're all set.
Slide your new rotor into place and then twist on a lug nut to just hold the rotor in place while you put the caliper bracket back on. Then put your caliper back into place and replace those two 18mm bolts. We'll fast forward as Don tightens those up. You want to torque these to about 85 foot-pounds.

Push your brake pads back into place. Then, put your caliper back down into place and replace those two 12mm bolts. We'll just fast forward as Don does this and tightens them up. You want to tighten these to about 30 foot-pounds.

Put your wheel back into place and then replace your lug nuts and tighten them preliminarily. We'll fast forward as Don does this. Then, torque each of the lug nuts to 100 foot pounds in a crossing pattern. Then replace that hub cap and tighten up each of your lug nut covers.

Before taking the vehicle out on the road, you want to just pump the brake pedal until it firms up and then do a stopping test from five miles per hour and then 10 miles per hour and you're all set.
