Last week I finally got around to replacing the rear upper shock mount bushings. The thud/thumping when going over bumps was driving me nuts. Anyway, I installed them, everything went smooth, shocks were dry ( no obvious leaks ), I even looked at the sway bar end links to make sure they werent rotten and cracked. They were not, the underside of this car is REALLY clean! Got it all together and the car is much quieter, but still has a noticable thud/thumping on bumps. What else will cause it? Possibly sway bar bushings? Its driving me nuts and I was sure the shock bushing kit would fix it. Its the same noise just less of it. Ideas?????????
