95 Camaro. Got the most annoying rattle rear passenger side.
Still there when spare wheel is removed.
Antennae support solid.
Not shock mount loose top or bottom end.
Nothing loose on suspension.
Nothing loose behind carpet on rear. Hatch secure.
WDF !!
Any clues out there ?

 

Check exhaust system,hangers might be toast. Grab the pipes and push up and down on them.

 

Looked at that and packed hangers, bent hangers....no dice but thanks.
At $50 a pair, I sit and wonder each time it rattles !!

 

Heat shield between muffler and gas tank?

 

when does it rattle, all the time, throttle up, hitting bumps, etc

 

I hate rattles. I have had to ride under hoods and in trunks to track them down on brand new cars. Once you track down the area maybe a Camera mounted in the area? I saw on online guy go crazy with a noise under acceleration he thought it was something rubbing. Turned out the camera picked up the axel tube turning under acieration. Had to weld up the axle.
