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 the front hub on this 2011 Chevy Silverado. It's a 1500, four-wheel drive. We're going to replace the right-hand or passenger side, the same procedure of the left-hand driver's side. This is the same for a 2007 through 2013 Silverado 1500 as well as GMC Sierra 1500 with four-wheel drive.

Items you'll need are a new hub or hubs from 1AAuto.com, jack and jack stands, 15 to 22mm sockets with ratchet. You'll need a breaker bar, and/or a pipe for some extra leverage, T-30 torx bit with driver, 36mm socket for the center hub nuts, some penetrating oil, wire brush, small pry bar, hammer, grease and a torque wrench.

Take your flat-blade screw driver and pry off the center cap. I apologize. I'm going a little bit out of order here. You can see we already have the wheel off. If you don't have the benefit of air tools, you're going to want to remove this cap by using a screw driver or a coal chisel and hammer or a large set of pliers, and remove that cap to expose that center nut. The center hub nut is 36mm. If you have an impact wrench do it that way. If not, you'll need a large breaker bar or a pipe for some extra leverage, 36mm socket, hold the brakes and remove the center hub nut. Once the nut is off, just make sure that your axle is free. After you get that nut off, then you can loosen your lug nuts and raise and secure the vehicle and remove your wheel and tire.

By hand, or using the steering wheel, turn so you can access the back of the caliper. Check for any abnormal wear. Make sure that the inside and outside pads are worn about the same amount. Also, on the rotor, make sure there's no deep grooves or uneven wear. This can indicate other problems with your brake system. There are two 19mm bolts that hold the caliper on up there and there. We'll fast-forward as we use a 19mm socket and a ratchet to remove those bolts. Once you have the bolts off, just put the caliper up and out of the way. Use a screwdriver and pry the brake pads out. You can see the outer one comes out pretty easily. We had a little trouble with the inner one. We actually switched to a larger screwdriver. You can see, after a little more force it comes out. This brake pad sticking in there like that indicates there's a problem, and you want to do some clean-up and some lubrication to prevent this. There are two 18mm bolts that hold the caliper bracket to the steering knuckle there and there. You can see here, we give it a try with just the socket and ratchet, but then we use a pipe for some extra leverage and loosen up that bottom one. Then, we'll loosen up the top one, and remove the bolts and remove that caliper bracket.

There's a T-30 Torx screw that holds the rotor to the hub. We're just using a T-30 torx bit with a ratchet to remove that. Then, on this truck, the rotor actually pulls off quite easily. If your rotors don't come off easy, douse the back side and around the studs with penetrating oil. Then, use two M-10 bolts. There's two threaded holes in the rotor. You put the bolts in, and tighten them up, and they press the rotor off.

Three 15mm bolts hold the hub in. You see them there and there Another one on here. You want to spray down the back side with penetrating oil. When I say the back side, I mean here where you can see the arrows are pointing. You want to douse the back side of the bolts where they come through the hub flange. The arrows are pointing at two of them. There's obviously one more for the third bolt that's morphed with the front. Here, we're using a 15mm socket with a ratchet and a small extension. You can see, you need a little bit of extra leverage with the pipe and the bolts come off. With some extra leverage they come out fairly easily. We'll fast-forward as he does the other two. Note here, as we work on the last one, don't take this bolt all the way out yet. You'll want to use a hammer. You might have to use a lot of force to get the hub to break free. Do that before you take that last bolt all the way out. That way the hub doesn't go flying.

Secure your brake caliper. Now, you can disconnect your ABS harness. Pull the connection out of the clip to the frame. There's a little button that you press to disconnect. Then, pull the rest of the clips from the control arm and steering knuckle. Now that we've got the thing free and disconnected, we're just taking that last bolt out the rest of the way. Then pull the hub off. Then, that last clip is easier to get to what the hub and backing plate out of the way. Just use a pair of pliers, squeeze the pins on the back and release the clip.

Here, you can see the worn-out part on the left, the new part from 1A Auto. Same connector, everything is going to bolt in exactly the same. Wire brush the steering knuckle to clean it up some, and grease the hub flange. Make sure you put the hub through the backing plate, then onto the axle and steering knuckle. Press it on there as you start the bolts in from the back side. Just a few notes as we speed up: Make sure you start all three bolts in first. You don't want to tighten any one of them up until you get them all started. Then, tighten them up evenly and you will want to torque them. Torque the three bolts to 133 foot-pounds. Now, route the ABS harness back in place and reconnect it.

Free your caliper. Then, reinstall your rotor. We're just going to put a lug nut on there to hold it in place, and start putting our brakes back together. We'll continue to fast-forward as we put the caliper bracket in place, and start the two bolts that hold it in place, and then tighten them up preliminarily. Use a torque wrench to tighten those up to 100 foot pounds.

Use brake grease or white lithium grease, and grease the ends of the pads where they'll sit in the caliper brackets. You can use mineral spirits or brake cleaner, even gasoline, anything that evaporates quickly, and clean off your brakes before putting the rest of it back together.

Put the rear pad in first. Put one side in first, and then press the other side in. It should go in fairly easily The same thing for the front pad.Now, you need to reset the caliper piston. We've put the old inner brake pad back in there. Then, just use a large sea clamp. As we tighten it up, you'll see the pistons go back into the caliper. Now, put the caliper back in place. Sometimes, those slide bolts will get stuck a little bit, so you have to push them in a little bit to get the caliper to slide down in correctly. Put the caliper in place and start the two bolts on that hold it. We're going to torque these two bolts to 50 foot pounds.

Fast-forward as we remove that lug nut, and then put our wheel back on. Put the lug nuts back on by hand first, then tighten them up preliminarily. Put that center bolt back on and tighten it to 156 foot pounds. Torque the lug nuts to 100 to 110 foot pounds each using a crossing pattern. Then, that center cap does have a little tongue that goes into a groove on the wheel. Put that in place. Them, most important pump your brakes a few times. Make sure that the brakes are working good before road-testing your vehicle.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.

Start off by loosening up these 22mm lug nut covers. We'll fast forward as Don does this. Once those are all loosened up, you can pull the hub cap 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 want to remove these two T55 Torx bolts. We'll fast forward as Don does this. Using a large C-clamp, just put it back behind the caliper here, and the other part right here on the brake pad, and just twist this in, and this going to push your caliper piston in and make it easier to pull the caliper off. Then, just remove the C-clamp, and lift your caliper up and off. Set it aside.

Now, using a flat blade screwdriver, just pry out your brake pad, and sometimes the pad is going to be stuck in there, you can use a flat blade screwdriver and hammer to pry it free. Now you want to remove these two 18mm bolts on your caliper bracket, and you can see, we use a piece of pipe for some extra leverage here. We'll just fast forward as he breaks the other one free and removes both of these bolts. Now, slide the rotor off. We'll fast-forward here as we just remove the clips that hold the ABS harness to the frame and steering spindle, and then there's a clip that holds the harness together, so just pull the clip back and disconnect it. Now, using a flat blade screwdriver and a hammer, just pry off your hub cap. You'll need to remove the center hub nut.

A few ways to do this: you can loosen this before you take your brakes apart, have somebody hold the brakes and do it that way, or you could use a large bar and put it between the lug studs to hold it, and then you could break the bar. If you have the benefit of air tools like we do you need an impact wrench to remove it. Then remove these tree 15mm bolts. You want to just use a 15mm wrench and another wrench for some extra leverage.

You just pry out, and once you've broken it free, you can just turn it out the rest of the way with the one wrench. We'll fast forward as Don does this to other two bolts and removes all three of them. Twist the hub nut back into place just a quarter of the way, and then hammer from the back of the hub to break it free. Then remove the hub nut and pull your hub out. 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.

Put your backing plate on to your new hub, and then push the hub back into place. Then just put those bolts back in. You may need to hammer the first one to get started. We'll just fast-forward as Don replaces the other two and tightens up all three of those. Then you want to torque those three bolts to 75 foot-pounds each. Now, remove this clip if you left your old one in, and then feed your ABS harness back into place, putting the clips back where they belong and into those brackets. Then reconnect your harness and clip it back up into place.

Replace that washer and your hub nut, and just tighten it back up into place. Push your rotor back into place, and then twist on the lug nut, and this will just hold the rotor in place. Turn the wheel and put the caliper bracket back into place, and replace those two 18mm bolts. We'll fast-forward as Don does this and tightens both of those out. Now torque both of these to 75 foot-pounds.

Now replace your brake pads and use a hammer if necessary to lightly tap that into place. Grease up your caliper bolts. Put the caliper back into place, and slide those slide bolts back in. We'll just fast-forward as Don tightens those up. You want to tighten these to about 30 foot-pounds. Replace your wheel, replace those lug nuts, and tighten them preliminarily. Lower the vehicle and tighten them the rest of the way. Torque the lug nuts in a crossing pattern to 100 foot-pounds, and torque this hub nut to 125 foot-pounds. Put the cap back in place and put it back in. Take your hub cap and just tighten up those bolt caps. After doing work on your brakes, you want to pump the brake pedal until it firms out, and then try a stop test from 5 miles per hour and ten miles per hour. Then you're all set.
