Ok, I know this is a longshot here, but maybe someone else has had this problem ...

Few months ago I started noticing a squeaking noise coming from my car ... it sounds like its coming from the rear passenger side but I can't be 100% sure..

It only happens when the car has been running for awhile ... On my normal 10-15 minute trip to and from work I don't hear it at all... And when it does happen the sound is kindof random, it doesn't happen when I hit bumps (so its not the shocks I don't think), and it doesn't happen as I'm turning... It really is kindof random. Its very noticeable when I'm going slow and idling forward ... but that might just be because of the speed.

Not sure how to describe the noise, but its a squeaking noise and its pretty damn loud ... With the windows down its very noticeable.

I already had the dealership lube up the swaybar bushings in the front and rear and that didn't help ...

I was thinking maybe something with the headers/exhaust because those pipes probably expand as the car heats up, but I couldn't find anything that the exhaust was rubbing up against.

If anyone has any ideas or suggestions please let me know!

 

check the rear brakes, Parking brakes and body kit if you have any.

 

maybe its a RAT?

 

Hmm, I don't think its the brakes since the noise doesn't happen when I hit the brakes??? Or could it be something rubbing up against the brakes somewhere else? ...

No body kit, so nothing to check there.

And CL- by RAT I'm assuming you mean the rodent kind and not some acronym for some car part, right? :P

 

check springs to make sure rubber slip on the last coil is on. Also check the rear shelf to make sure all clips are attached.
