Trying to rule out causes of noise: Rear end clunk

STS Scott

Recommended Posts

After getting the STS back from a general service and oil change, I am seeking the help of the board here, for the cause of a clunking noise coming from the rear end, when going over choppy roads. The exhaust banging against the underbody does not seem likely, for it has oodles of clearence, nor do the suspension bushings, which is what I had them check out during the service - and they said they were fine.

So what else is left back there that could be rattleing around? Struts?The trunk is perfectly clean, so I can rule out things banging around in there, too.

Any Ideas?

We recently had someone that described the same problem. Jack the rear wheel up and grasp it at 12 and 6, and 3 and 9 o' clock and see if you have any play. If I can find the post I will refer you to the link.
