Post Need help with unknown sound

When I drive my car through some rough surface or small bumps on the road, there's a metal cling coming from, I think, the back of the car. Sounds like metal hitting metal. I tried to look under the car to see if I could find the source with no luck. Anybody know what it could be? It doesn't always sound, is just when I go by over some small bumps and rough surfaces. Thanks for any help.

I have a single 12 inch sub in the back and depends on some bumps my car hits itself pretty card and its always the rear. i think my shocks are blown......

I hear it at the rear, not sure if it's the right or left side. I don't race it a lot, and have the stock sound system. I don't have any BMR suspension stuff nor a LM. I do have a Flowmaster muffler but the noise was there before I installed it.

I have the same sound but it only started after my corsa. I need to get the *** up on ramps and check, but what I think it may be is a metal heat sheild about the rear axel (right side of car). And with a 3" pipe there isn't a whole lot of clearance. I have never heard of shocks rattling?

I have all stock suspension and nothing in the trunk. The rear end on these cars is just noisy. However, if you have an aftermarket exhaust, I would check to see if the over-axle pipe is banging.

Have you checked your spare tire yet?Sometimes they come loose and make a "cling" sound whenever you hit a bump.Good luck.

Thanks for the replies guys. I guess I'll check the spare/jack to see if that could be it.

I've noticed the same noise in my 2000 SS. A tiny, "clink-clink-clink" that seems directly related to over-road motion, coming from the rear. THE THING THAT I NOTICE IS THAT IT GOES AWAY AFTER I'VE DRIVEN A FEW MILES FROM A COLD START, AND DOESN'T RE-APPEAR UNTIL STARTING OFF ON NEXT DAY'S TRIP.
Do you guys have any ideas on what might be causing this?
