Q: Anyone have any
suggestions for resolving a loud thunk from the right rear wheel of my 2002 T/A
WS6? It occurs whenever going over a significant bump or pothole in the road - a
resounding thump that can be very loud, depending on speed, and sounds an awful
lot like bottoming out.
I’ve had the rear shocks and coil springs replaced,
and both of them improved the ride quite a bit, but only reduced, didn’t
eliminate the thump. Still occurs at anything over 25 MPH.
Neither my regular mechanic nor a suspension
specialty shop have been able to identify the source, much less fix it.
Have your heard of similar experiences of the
problem and how it was managed to be solved?

A; My Trans Am and many
others have the rear bump stops replaced. Since the GM part is hard to find and
very expensive I used stops from a Jeep that are widely available. You only need
to trim off a small section to make it fit- very east with a cut off wheel. The
stops wear out on these cars and were probably defective.
Also check to see if your spare tire is secured
properly. I had that problem once. Made a clunking noise.
