I recently purchased a 2007 LT3 Tahoe. I am having an issue with rattling noise inside by the back buckets. My girlfriend jumped back there while we were going down a bumpy road and discovered it is the forking light. Now it is driving up the feeking wall. Has anyone had this issue. I am bringing it in to the dealer so he can replace my grill since I have hard water damadge to it. The hard water damade was from the dealer he purchased the truck from. What can he do with this. It like a kid is shaking a rattle.

Thanks Hugh

 

I HAD RECENTLY BOUGHT A NEW 07 TAHOE LT3 ALSO AND I HAD THE SAME RATTLING BUT MINE IS COMING FROM THE DRIVERS REAR DOOR PANEL. WHILE ON DRIVE ABOUT 30 MPH I HEAR CONSTANT BUT IF PUSH AGAINST IT, IT GOES AWAY. I NEED TO TAKE IT IN TO THE DEALER TO GET IT CHECK.

 

i have lt3 too and i also have rattling coming from back i just dont have time to take in but seems like coming from one of the rear vents~

 

A couple of people have had an issue wit this. A quick search revealed this thread...

Basically the headliner around the rear light area comes loose. Takeit to dealer and have them look at it. the tape or clips will be replaced.
