When ever i start my car "cold" and im backing out of the driveway, or out of a parking lot i get this weird clunk noise that sounds like its coming from the rear. i also get a similar noise when i get out of my car. The thing is, if i push on the front or rear of my car to make it bounce up and down, it does not make any noise at all? i know this isnt a very thorough \description of whats going on but any help would be appreciated.


Its a 1992 bonneville se with about 140,000 miles on it

I dunno if its the same problem but when the donut at the top on my exhaust by the manifold went bad my car would clunk going into reverse.

Well, if it'* coming from the rear you've eliminated about 50% of the possibilities on where this noise is coming from. Here'* my laundry list of targets to shoot for. The exhaust, rear brakes, rear suspension, that long lost soda bottle in the trunk. Good Luck.

thanks guys. i know this is a little off topic but should i be able to burn out in my car stock? it used to be my dads car and i could have sworn i was burning out in it 3 years ago, but now i cant even come close to making the tires squeal.

GM has a bulletin on this condition. My SE does it too sometimes.
Its coming from the pressure in the Gas tank.
Nothing to be concerned about ......so the dealer said.
