I know it's not possible to know what to hear the voice via the forum but I was hoping that there might be some common issues generating the noise from the rear of my 01 turbo.

When I go over certain bumps any speed it can hear this low soft thump or da da - da da like noise from the rear.

From my car experience it almost sounds like the strut missing the little plastic ring, or a mis-installed spring, or some plastic part hitting the body panel

Any ideas or solutions?

Thanks

 

maybe loose exhaust??

 

I should add that everything this happened when everything was stock in my car, exhaust & suspension. Now w/ the aftermarket exhaust still makes the same noise.

 

check your wheel caps, on a car of mine I had same noise and it was a loose wheel cap

 

check how secure your sway bar link is. If its loose you may hear a rattling type noice over bumps.

 

Engine fan.

 

do you mean the one on the rear deck, because when i hit it the fan it's self does make noises the blade seems a bit loose w/ the body...

 

muffler bearings.

 

what is a muffler bearing and how can you tell if it needs fixing? thanks

 

I think I heard something like that (thumping noise when going over bumps) when my stock suspensions were about to go - changed to JIC and it went away. The rubbing on hard accel went away too ..

 

Yes. My fan housing used to make a terrible thumping when driving over freeway expansion slots.
