If the vehicle develops an annoying, clunking sound when driving over bumps it is usually the struts and strut bearing plates. These may need replacing at 100,000-125,000 miles or sooner. If the noise is a more of a squeak or groan, it can be usually be eliminated by spraying a light lubricant on the suspension bushings 1-2 times per year.Google+

Toyota Celica Sound When Driving Over Bumps May be Struts/Bearing Plates
Toyota Celica Problem
Visitor, 1993 Toyota Celica, 230,000 mi
I was not experiencing any problems of significance for a vehicle of this age and mileage. However, our temperatures went from ~60 degrees to lows of -15 degrees in under 48 hours. When I had last driven the car, it was 57 degrees outside; all was well. Then, two days later, I needed to make a trip to the store while trying to get out before a lot of snow had fallen. The temperature was down to -7 degrees, and I didn't make it 200 yards before pulling over to see if something was obviously wrong. The slamming knock in the passenger rear side was so bad that I thought something had completely broken. Over the past 96 hours, I've driven in a range of temperatures from -7 degrees to 35 degrees. At the latter, the problem is almost unnoticeable. However, when driven again at a temperature of 2 degrees, the problem returned. I plan on seeking resolution as soon as financially possible.
