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 Tailgate hinge on this 2002 GMC Sierra 2500HD. It's the same process on most 1999 to 2006 GMC Sierras and the Chevy Silverados. The tools you'll need are 13 millimeter socket and ratchet, penetrating oil, anti-seize and it's helpful to have two people as you'll see in this video.

You want to start by just putting the tailgate down. As you can see, the hinge on this truck is in pretty bad shape. You want to just push the cable up and then it should pull off. Depending on the condition, this could be a little difficult, but just keep moving it around, and it should pop off. Now, while he tries to get that cable off, this is where it's helpful to have a second person. So, the other person can hold the other side when it comes free, and the two of you can move it aside.

Here's a closer look at the condition the hinge was in. As you can see, it's in pretty bad shape. We just want to spray these bolts with some penetrating oil. This is going to help to remove them. Now, you just want to use a 13 millimeter socket and a ratchet to just remove these two bolts. We'll fast-forward as he removes these. Now, what you want to do is you just want to pull this bracket off. This one just comes right off. Just move it around a little bit. Then, we'll fast-forward as he removes the two 13 millimeter bolts on the opposite side. This hinge is a little bit harder to get off. He's having to use a flat blade screwdriver to kind of pry it from the truck. There it is.

Now, what you need to do is you need to remove the two 13-millimeter bolts on the tailgate itself. We'll fast-forward as he removes these two. The clip should just come right off. We'll just fast-forward as he removes the other two bolts and the clip on this side.

Here are, obviously, the new hinges on the bottom and the old hinges on the top. The hinges from 1A Auto are going to be an exact replacement, and they're going to bolt-in just like the original and work a whole lot better.

So you can see here, he's just pointing out that they're marked "left" and "right." The left side is going to go on your driver's side, and you're going to want to take the shim off the old hinge there and just put that on to the new one. What he is doing right here is he's just putting some anti-sieze onto those bolts. You just want to put that shim and hinge into place and put the bolts into place. We'll just fast-forward here as he tightens up those 13 millimeter bolts. Now, you want to follow the same process on the other side, just putting the anti-sieze on the bolts, putting the hinge into place and tightening those bolts.

Again, you follow the same process, this time, for the hinges on the actual tailgate itself. You're going to want to put the round, the full-circle end on to the driver's side of the tailgate and the half one on the opposite side. We'll just fast-forward through this process.

Now, you're going to want the second person again, and you're going to put the driver's side end on first and angle the other side up and on to the hinge, and then connect those cables on either side of the truck. As you can see, everything looks a lot better now.
