I am trying to identify a rattle that comes from the rear of an 83 300D. The car has 171K miles and recently moved from a southern climate to Minnesota. The "rattle" is pronounced when going over bumps and making turns, more so to the right than to the left.

It sounds as though something is loose or maybe the muffler is hitting something under the car. I've crawled under and the muffler looks good, no missing donuts and it has the right amount of play. I checked the sway bar and that seems OK too. I don't see any loose components such as shocks or springs which would be making this noise. When a rock the car when parked, I can't get it to make the sound it makes when on the highway. Any ideas or recommendations would be appreciated. Thanks!
