So recently when I am driving my car it sounds like a I have a can of spray paint in my back right C pillar... My girlfriend was driving behind me and she said it was audible from in her car to with her windows down.. It only happens when I go over bumbs and uneven pavement. But its loud.. car handles fine.. took the tire off tomake sure all the suspension components were tight and they were.. mods listed in sig

neuspeed rear sway, with rs4 endlinks, bilstein adjustables with neuspeed race springs.. I am worried.. my springs have a rubber guard on them..So I dont believe its coil slap...

please help

I had a weird problem, don't know if it's related but anyways... One of my rear brake pads wasn't seated correctly, so it wasn't being held in properly and was able to slide around. The noise was most audible going over bumps, but there was no noise when the brakes or e-brake were applied.

hmm I checked the rotors and they seemed tight.. this is so weird.. I crawled under the car to see if the sub frame was cracked or anything.. from what I saw everything is intact/tight. I am running my sway bar on the stiffest setting...

Did you see if any body parts were loose. Maybe when you hit a bump some plastic smacks some stuff. If it was a shock or suspension component it should make the noise cornering.

The rear is like unibody. It sounds like metal on metal knocking back and forth. very similar to the noise of a spray paint can w/ the marble in it.. it doesnt make any noise while im cornering.. only when driving and going over bumps..

Did you peek u der and see in anything is hanging off or such. If it was suspension it would pro ally do it while the suspension is being stressed in cornering

what type of rear suspension did you have. i might be wrong but i thought there was a spit in the 97 98 area when they changed the rear suspension from the old style with the adjustable upper control arm. that old style has the control arms as a common problem along with the bushing for the lower control arm towards the front. to feel play it the upper control arm you have to jack in up and try and wiggle the tire from top to bottom VERY hard and you can feel play in it. the lower bushing have 2 big washers that contain the bushing if the bushings are bad you will notice the inside edge of the washer will be hammered/polished from hitting the bracket.

hmmm.... I will investigate and report back.

thank you!

Look at your subframe again - if you don't have the triangulating subframe braces in there, you're not supposed to run the stiffest setting - it's known to crack subframe.

check the rear muffler
