I have no clue what this could be my only guess is something to do with the wheels. Whenever I'm on a bumpy road i hear a rattling outside, underneath my car. my boyfriend thinks that my shock might be loose, or just that something is loose. any information would help. thanks guys.

Also... The heat shields on the exhaust pipe forward of the cat converter are a perennial source of 240 rattles. The tack welds eventually rust through. Fix using clamps, screws or cut them off.

Amanda -- it could be a lot of different things. Muffler/tailpipes loose? Rear suspension bushings shot? Loose/bad shock? What might be useful is to put a piece of cardboard down on the ground, crawl underneath a little bit, and have your boyfriend stand on the rear bumper and bounce the car. Better yet, have *him* lie underneath while *you* bounce the bumper. Make sure there's adequate clearance -- avoid obvious low spots. While he/you are underneath, check all the suspension nuts and bolts with your fingers to make certain that there isn't something obviously loose. Grab the suspension bars and give them a shake and twist. Obvious movement indicates bad bushings. Grab the exhaust components and shake them around. Any banging or rattling?

This shouldn't be too hard to track down.
