Brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the Internet. Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my twenty-plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts installed correctly, that's going to save you time and money. Thank you and enjoy the video.

In this video we're going to show you how to access and replace the wiper transmissions on this 99 Suburban. Help you with that squeaking noise from your wipers. Same as this generation Suburban, Tahoe, Yukon, as well as the trucks. Tools you'll need are pretty simple: flat blade screwdriver, a Phillips screwdriver, and an 11mm socket and ratchet. To remove the windshield wiper arms it's pretty easy. You flip the arm up and there's a little tab right here. That pulls up and then you can just work your hands under there and pull it up and off. The same thing for the other side. After you have removed the wiper arms, you're going to remove six Phillips screws. One there, one in that round hole there (you probably can't see, but it's in there), one in there, one in there, and then finally one right there. So, I'll remove those six. So, on these corner ones, once you pull it up, there's this little grill here. You just pull that back up and off. The screw comes out with it. After you've pulled those covers back on the sides there's two more screws underneath on the edges. There are two more screws right here along the edge to remove. Once those screws are out, pull it up over the wiper mechanisms, and don't forget to disconnect your windshield washer hose right here. Just for orientation, there is the steering wheel. Here is your linkage where it hooks to the wiper motor.

Right here is your wiper arm transmission and then over here is your other transmission. We're going to start out by putting some penetrating oil on those bolts. Now that I've let my penetrating oil sit on there for a little bit, loosen it up. The driver's side linkage will come off. Now the passenger side linkage comes off. Here is our transmission. These are 11mm bolts, going to press on there. Once you have it unbolted, just press it down through, then right up and out. There is your linkage out of the vehicle. Also, the passenger side, the same thing. Remove these three bolts. From the other side, going to pull it right out. And there is your passenger side linkage out of the car. On these wiper transmissions you can see the new 1A Auto part versus the old. It's all the same, but everything is a whole lot tighter on the new ones. It has new bushings down here with some grease in them. That's really going to help tighten it up and stop the squeaking. Same thing with the driver's side. Squeeze a bolt right in and fit just perfect. As you can see, I've cleaned up the stud on the wiper motor. Before I put my transmissions back on, I'm going to put some regular old bearing grease right on here. I'm going to place my passenger side in here first. The arms do go up towards the top of the vehicle. I'll put it up in and I'm just going to put one bolt in for right now. Just start it. Same thing over here, lay my other side in.

Speed up through me kind of fumbling around trying to get this routed right. Get it roughly in place, put one bolt in. You'll need to re-use your original bolts because they are self-threading. You want this one to go right on that inside ball on this truck. We'll just tighten them up a little bit because we're actually going to align them first. You want it popped right on there. Tighten it up a little bit. It is okay if they are sliding a little bit. I've got my wiper arms back on and I can take them back off to put the grill on, but you can see without those transmissions tightened you can move your arms back and forth a little bit. You're just getting them right where you want them as far as their parked position. Then you can tighten them up. Then, after you have them tightened up, it's a good idea to run them a couple times just to see if they go down back where you want them. I'm actually going to adjust this one down just a little bit more. Once you have your wiper arms where you want them, you want to tighten up the transmissions. Then, I'm kind of fast-forwarding through putting the grill back on just because of the YouTube ten minutes. You want to put the two screws in that you can reach underneath the hood. Put those on, then lower the hood. Put your corner screws that are underneath on first, then put the corner bezels or trim back on, and tighten up all the rest of the screws. You should be good to go with some nice, quiet, new wipers that are working correctly. Obviously, once the grill is back on, then you put the wiper arms back on as well.
