Back Glass

[tx07tahoe]

So for the past couple of weeks I've heard this sound in the back of my truck. It sounds like the back glass is loose. Everytime I go over a bump it rattles. Its driving me nuts any suggestions on what may be loose.

x2!!! But im not sure if mine is the glass. Its hard to track down when your driving.... Drives me crazy though.

I had someone sit in the back.

Yeah I had an issue like that, ite ended up being the rear d-pillar caps that sit right beside the rear lift glass, the mounting tabs broke on them so they started rattling and needed to be replace with a whole new d-pillar cap, warranty fixed the issue.
Check your caps in the rear both left and right (they are right ontop of your taillights), mine was the left one that went bad.

Those appliques on the d-pillar is what was causing my rattle too. It drove me nuts for 6 months until I finally figured it out. My rear lift glass was out of position though from when I swapped out my 3rd brake light.

I have the same problem, those are great points Modded as usual. I will have to check that out too. Its strange though, sometimes it just drives me crazy, and other times I dont hear it.

I had a rattle that I also thought was somewhere on the liftgate, turned out to be the rear domelight housing, pulled the housing and placed a piece of memory foam between the housing and the roof, no more rattle...

There was a TSB out for this exact issue.
