I know there are several people who have experienced this issue. The rear swing door has an extremely loud and annoying squeak which you constantly hear after every little bump while driving. I finally got around to checking out what the deal was. I took off the inside trim and the soft sound barrier and looked inside my door. I was actually surprised by the lack of moving parts in there. It's just the two latches for the door and window which are connected electrically. Every time I knocked on the spare tire the entire door would squeak to hell.

I finally tracked down the cause of the squeak which was basically the entire door itself. Somehow the bottom of the structure loosened up a bit on itself. If I pull in on the outside of the door while facing out the sound ceases to exist. The only way to fix that would be a new weld or something, at least from what I saw. For now I took off the entire spare tire and threw it up top which eliminated the noise since there isn't a load causing a back and forth motion on the lower part of the door. Maybe I'll start checking a junk yard for a new door.

My rear door loosened up and rattled quite a bit- don't remember a squeak, but my fix might work for that too. The door latch attaches to a hook on the body, and that hook is easily adjustable. I think it is two large torques (star bit) bolts that need to be loosened, then slide the hook forward a bit and tighten them down. I have to slam my gate pretty hard to get it latched now, but it's snug as can be.

If that doesn't work, get yourself some mud tires, a magna flow muffler, and crank up the tunes. That oughta drown out any squeaks you may hear!

It wasn't a rattle, just the loudest most annoying squeak ever. I should have recorded some audio. I'll check my door latch though.

I also noticed a crack developing near the mount for the spare tire assembly on the inside structure. Guess my tire was pretty heavy.

I was having the problems too. Using whit lithium grease.....

I greased the seats latches. That took care of a little.

I adjusted the door latch and greased. That took care of a little.

I greased up the window latch AND put a piece of the fabric side of velcro against the "pusher." No more sqeaking at all.

That rear window was acting like a sounding board.
