Rattle under dash

[mbeach]

god knows you're right about rattles driving you nuts.

I've had one in the back right quarter panel that to this day I've been unable to track down. Very fustrating problem.
Its definitely driving me bonkers though, so I feel your pain.

I have this same clunk/rattle in my rear quarter. I actually gave up on trying to find it myself and took it to the stealership -wouldn't you know it, the truck was perfectly silent when we were driving it around. Mine rattles less when I have a full tank of gas, I'm starting to think that it's a loose gas tank strap or something.

I'll have to get my hands on a trunk monkey for some on-road diagnostics.

Mine doesn't rattle when its cold, only when it warms up. I haven't been able to work on it all winter because it wont happen when its like 20 degrees outside. Now that its warming up, I'm determined to find the problem even if I have to rip apart the whole rear end (I already have once unsuccessfully)
