Help with weird noise from read suspension...

I'm a fairly new Celica owner, and I have had my '92 GT for about 6 months now. I have just started hearing a thumping noise coming from the rear-passenger side strut tower area. The sound is just one solid thump when I go over a bump with that wheel. I thought the top nuts that hold the strut in place could have been loose, but they were tight, so I was wondering if there is a bushing that could be worn or if it could be the sway-bar? Any ideas? :uhoh:

could be the shock...i had one go out on me during an autocross in the dirver side and made a clunking noise when i drove around with it...only way to know for sure is to pull it out and check

Cool. I'll pull it out this weekend, then. Thanks.

yea, same thing happen to me when i used to drive a 91 celica, the shocks were bad.
