Have this rattle from the rear. Does the trim under the rear window just pull straight off? Any tricks?

 

check the rear seats, if the seat back is loose it will squeak / rattle.

 

trim removal is a pain but doable in a few hours. Lots of hidden screws to yank it off, and the rear panels come off a specific way so as not to break tabs. Ive been deep in there and not much that could cause a rattle except the seat belt mechanism.

Some 2007 cars has an advisory for fixing a weld (from memory) in the rear, did your car have this performed? It would cause a rattle.

 

Thanks for the tips guys!

Will go over the car and see what I can find. The only advisory on the car was to grease the turbo's.

 

If you are hell bent on getting in there let me know, I can take some pics and show you how its done. Pretty much everything needs to come out to do it right. My rear drivers side seat belt makes a tiny rattle, but its the mechanism itself, decided I'd live with the noise vs. replace. Oddly it did go away!
