Here are the items you'll need for this repair: 10mm socket, ratchet, T30 Torx socket, flat blade screwdriver

You have eight pieces of hardware securing the cover and the backplate onto the tailgate. Ours have clearly been replaced a few times and are various styles and sizes of hardware. Use the appropriate tool and ratchet to remove whatever hardware is securing your plastic back cover. If you don't have this plastic cover the hardware should be the same and in the same locations to remove the steel backing. Remove the plastic backing if you have it. Once you remove your plastic cover, if you have one, you'll have two T-30 Torx bolts you need to remove. I'm pretty sure this is the original hardware that should have been holding the plastic piece of the tailgate onto, so you probably already have this tool out. Remove the metal backing.

Use a small flat blade screwdriver to pry up the tabs and release the lock rods from the tailgate.

Using a 10 millimeter socket and ratchet, you can remove the two nuts securing the tailgate handle to the tailgate. You can then pull down and fold the bottom out to remove the handle from the vehicle. Use a small flat blade screwdriver to pry out this snap clip and wiggle the lock mechanism out of the handle.

So our old lock is fine, but if you need a new one, it'll install the same way. Just drop it into the opening. Reinstall your snap ring, and you're ready to reinstall your tailgate handle into your truck.

Reinstall the tailgate handle. You'll then have to set the mechanism back on there. There's some plastic clips on the bottom of the mechanism to lock it into place. Once it's in there, you can reinstall your two 10 millimeter nuts. Tighten them down with the socket and ratchet.

Now, when reinstalling the latch rods, you'll want to pull the slack out of them without actually moving the latch and lock them back into their tabs. Now before we reinstall our back cover, we'll open and close the tailgate a few times to make sure our latch rod adjustment works.

Now, if the tailgate won't close fully on one side, you'll need to back off the adjustment a little bit and give the rod some more slack. Or if it's difficult to open with having this off, you can reach in there and pull it manually to release, and then you'll want to pull a little more slack out of the latch rods.

Reinstall the metal cover. Now, if you have the plastic cover, start by installing the two T30 Torx bolts. If you don't have the plastic cover, reinstall all 10 of your T30 Torx bolts at this point and tighten them down. Now, if you have the plastic cover like we do, reinstall it. You should have eight T30 Torx bolts to reinstall. We have miscellaneous hardware that we'll be putting back in. Close your tailgate and you're good to go.
