Ok i had loud clunking so bought subframe collars, bam the loud clunking is gone, BUT now i notice only when i let off the gas at mid-rpm to high rpms, i hear some rattling noise behind the rear passenger side panel. Not sure what it is. From the outside it would be behind the rear fender. Common problem? Any1 thanks

 

not quite sure, but one of the most annoying rattles i had was my exhaust was loose on the cat. this probably isnt the case but maybe it'll lead you somewhere.

 

loose harness, loose bolt/screw, loose panel, broken panel fastener, etc. could be a lot of things. Try takin g the interior panel off and seeing what's going on behind it.

 

k thanks ill take a look and ill let u know what i find.
