Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and, please, next time you need parts for your vehicle, think of 1AAuto.com.
In this video, we're going to show you how to replace the air compressor on this 2002 Chevy Suburban with the air ride system. It's the same part and similar process on these Suburbans from 2000 to 2013. The items you'll need are a new air compressor from 1AAuto.com, 8 millimeter and 12 millimeter socket and ratchet with an extension, T25 Torx bit, Philips screwdriver, pliers, vise, hammer, wire cutters and wire strippers.
Now, your air compressor is right here and you should probably start off by removing your spare wheel. Okay, as you can see, the compressor on our vehicle is in really poor shape and this video is basically going to show you how to replace just the compressor motor, the electronic part. You're going to reuse the other compressor parts. On this vehicle we find that it just doesn't work because of the poor shape of the rest of the compressor. If your vehicle is rusty, you may want to consider, and I'd highly recommend, spending the extra money on the entire assembly that 1AAuto sells. Then, what you want to do is just pull out the clip on this hose and pull it from the compressor. Then, you want to just reset that clip by just pushing it back in. You want to loosen these two 12 millimeter nuts and the one in through this hole, and we'll just fast forward as Mike does that. Now, lift the air compressor up and then pull it forward. You want to just push the tab on this harness and pull it free and then twist this hose free from up here.
Now, you want to just pull out these clips holding this cover into place, just using a pair of pliers. You just want to hold on to the clip and just pry it out. Do the same to the other two. Then, you want to remove these three T25 Torx bolts. We'll just fast forward as Mike does this. These are some of the parts that if they break . two of mine broke off. So, they were unusable. If I wanted to just use the motor, like I said we ended up going with the whole assembly that 1AAuto sells.
Now, on the left, is the old motor; on the right, is the new one from 1A Auto. You can see they're identical and they're going to fit exactly the same. You do have to transfer a couple of things over from the new motor though as we'll show you right now. First, you want to just pull hose free. Ours is in pretty bad shape and ended up taking half the motor with it. Just empty it out and push it into place in your new motor. Then, just pull up on the tab and disconnect this harness and then pry this connection from here. It helps to use the screwdriver to just kind of pry it out. Then, you just want to just remove this Philips screw right here. It's pretty rusty, but we do the best we can with it. Now, remove the wire ties using some wire cutters. Now, you just want to pull back this cover and pull back this cover. There's a clip right here and then clip right here. Now, you can pull your wires free. Again, just pull back that cover off of each of these wires. Now, you just want to line up your wires and then clip the wire and then use your wire strippers to strip the end of the wires. Now, you're going to want to twist the ends of those wires that you just stripped and then push the matching colors into the splices: the red wire with red wire, white wire with white wire, blue wire with blue, black with black. You can now use your crimping pliers to crimp the splices. We'll fast forward as we repeat that for all four wires.
Now we have the assembly in a vice and we're going to twist the drier free. You're supposed to be able to take these T25 bolts off and remove this bracket and transfer it. Let's see how we can transfer. Transfer it onto there and then you would wrap these wires around and clip them to that bracket. As you can see, from our old motor, there is just no way where you're going to be able to get those things apart. Now, take this air filter and just put it into a vice and twist the top off and you want to do it carefully because there is a spring inside of there. Now the new air compressor comes with a kit to rebuild this so just pull the spring out, pull the gasket off, pull this screen out and this pad. You want to dump out these pebbles and then pull out the pad on the bottom and the screen that's on the bottom as well. Put the filter back into place and put the new screen down in and the pad, then the new beads, then the pad and then another screen. Now, you can take your new spring and push that into place and then take your lid, put the new gasket around the lid and twist that down into place. Now, take the new O-ring and put it on to this end here and then just twist this into your new air compressor. Then you want to just remove this front screw using your 8 millimeter socket and ratchet and just pull that free and you can put your wire from your old compressor on to it and then put the bolt back down into place.
Reconnect this harness and then you can push these pads into their proper holes and we'll show you one of them and you just push it up into place and then repeat the process with the other two and because of the condition of our old bracket, we can't really show you putting the compressor back into the bracket but you would just put it back into place and then replace those three T25 Torx bolts and then just push that harness back into the bracket. You take your harness and connect it to your new compressor. As you can tell, the whole assembly that I'm holding is a brand new unit. Like I said, the compressor in our vehicle was so bad that this was the way we had to go, and I would recommend that, if your compressor is as rusty as ours was or even close, spend the extra money and get the whole assembly. It's a matter of just three bolts and a couple of connections to remove and replace. Push this hose up into place, and then push this hose back into place as well and then you're all set

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
Raise and support the vehicle. The air pump for the air suspension is behind the driver's side rear tire, located on the frame. These two bolts here, you actually don't loosen them. There are little studs that will slide off. There is a bolt up here. You're going to have to go through the frame. It's 13 millimeters. Unbolt it. Once that's unbolted, we'll knock this free. It'll come backwards. We'll pull it down. Unclip from the connectors. But before we do that, we're going to follow this line up and there's actually a little pick up, probably where it picks ups air. It's up here on the filler neck with a clip. I'm going to take a prying tool and pry off the barbed clip that it's on. There it is. There it is. Slink through a couple of other things here. Fish it out of here.
Now I'm going to remove the 13 millimeter bolt that's up and through the frame, and we'll get this pump loose. Bring it down and unhook the connectors on top. Spray some rust penetrant as best I can. It's a hole through the frame. I can feel the nut. I can't see it. Spray some rust penetrant in there. I know it's on a stud, so I'm going to use a 13 millimeter deep socket and an extension in a ratchet. So it actually wasn't that tight. These are studs that go through the frame and hold onto it. I shouldn't really have to loosen them, but maybe to relieve a little bit of pressure with this rust, I'm going to spray some rust penetrant on them. Spray back here, too, to help them slide. Just give them a little loosen. They're 13 millimeter. It's coming loose. I'll grab it with both hands. Try to work it back and forth. There it is up. And up and out their slots that come right out.
It's still connected to the top, so I'm not going to let go of it. This line's actually already been disconnected. Disconnect the electrical connector. Disconnect this line here. This plastic tab off. Get this off. Pull the air pump out.
Here's our old air suspension pump we pulled from the vehicle and our brand new one from 1AAuto.com. As you can see, it doesn't come with a bracket, so we'll have to swap the bracket to our new pump. But, other than that, it is pretty much identical. It's got the same style electrical connector. Adjust it just like that. This electrical connector is the same. It will connect to the sensor up here. It comes with a sensor we will install up here.
We'll swap over this airline. Reconnect the airline that's over here in the back side of the pump. So if your air suspension isn't working, this will fix you up and get you on the road. Let's spray some rust penetrant on the backside of these bolts here. Torque bolt here and then another one in here. Get a better look at them. Have to remove this rubber protector. I'll take a trim prying tool and just pry these Christmas tree clips out of here. Pry them out. Bend the cover back. That should be enough.
So there's actually a bolt here, here, and here. Going to remove those. These are T25 Torx. Remove this first one. Stuck in there with rust. This is the side, it came out with a little bushing part. That's okay.
This airline is attached, so I'm going to slide it out of the clip. And this airline is attached here. Spread the spring clip out that's holding on. Should slide off. The spring clip is removed. The spring clip back where it was so it doesn't get lost. Pump out of here. There's our brackets separated. I need to swap this air hose for the little filter where it sucks in air. This hose here on the new pump goes through this little block right into the pump.
On this original one, it's capped off and then they used a Y fitting so that it ends up being connected from here to here. Basically, the same exact thing except I'm going to remove it from here. Actually, if it's too hard to remove from here, you can cut this off here and then just place it on the new pump. I'm going to use some hose cutters. Just cut this. Place that on the new pump. Take this elastic band off. We don't need it anymore. Place our new pump back into the original bracket. Feed this hose down like this. Fiddle with the bracket a little bit. Put this hose back into the clip. Take this other piece off.
Reinstall this screw. T25 Torx. Just going to get one started. And then line up the other one, so the way the pump is not holding on the screw. This is a rubber bushing, so I'm just going until I feel it get tight and then I will stop. The last one at the bottom. Little trickier with the rubber piece here, which I get started by hand first. Going to pull out this other clip that's in here. Give me a little more space. That's easier. Push our clips back in, our rubber protector. Go ahead and clip on this airline. Put this clamp down over it. These go into the car. Need to add this pressure sensor. It has a lock in washer, just like original, and an O-ring on there. Doesn't matter what direction you install that washer. Get it threaded by hand to get it started.
I installed the pump into the bracket first so it would be easier to hold it while I tighten it. You can use an adjustable wrench or this is 24 millimeter. I'm just going to tighten it down. Don't over tighten it because it is just going into plastic. That O-ring will seal, so as you feel it start to get tight, be able to turn more with the wrench a little bit. That feels good. Install the electrical connector into it. It connectors here. It sits like this in the car.
Now it's ready to go back up into the car. Slide these two studs back in the holes in the frame while lining this one up. I'll reach in from the back side of the frame and put in this 13 millimeter nut and we'll reconnect the lines. Going to be all set. Slides up here. Slide forward to lock it in. Using a 13 millimeter deep socket and extension, reach up into the frame. And tighten it.
Feel like it's tight. I'll stop. Place our air inlet tube back up onto the filler neck where it came from. Clip it back into place. Reconnect the airlines and the electrical connection on top. And the pump is replaced.

Good enough for what I do. Easy to install. Instructional video walked me through step-by-step to complete the job.
Compressor was a good fit! Video helped tremendously!
I purchased and installed the compressor along with new rear shocks in September 2025 and the compressor has already stopped working. It looks like I'll have to get a new one.
Yes I would recommend this but don't buy the struts they are so stiff I regret buying them.
Super easy install!!
Love 1A Auto. Fourth time I've used them and have been spot on every time. The video to repair/replace the parts have been very helpful and made the job seamless. I'm am not a mechanic but fairly handy and the video really helped with the job.
Riding high in the sky again and putting it on was easy just watch the video and get to working . I been dealing with A-1 for years and they are the next distributor close to having parts like the dealership thanks.
Part installed easy!!
The part worked well. Fit was correct. Some wiring on the unit was routed not quite right for the application. Best left to a proffesional tech I if you aren't comfortable with repairing vehicles
Perfect fit and quick repair to the suspension , thanks for the very fast delivery
It's the complete deal. Install as 1 unit. I made the same mistake ordering the air compressor but not the whole thing and it was a bit more complex than I wanted to deal with so I sent it back and got this. They posted the wrong video for this unit. They do have another video if you look on YouTube that shows this one being removed and installed it's super simple. Three bolts to remove, unplug the electrical connection and disconnect the airlines lift up housing and remove whole unit. Take new unit install with the 3 bolts, plug in electrical connector and reconnect air hoses and boom good to go
Thank you for the inquiry. This will come as a new compressor unit, it will not come with additional parts other than what is included for the complete assembly.
