Hi Everyone, its been quite some time since I have visited this board.

I was driving down the Highway and i hit a pretty decent size pot hole with my 2001 C320. Ever since, if I hit a bump just right, i will hear a noise that sounds like a spring, it just goes "boing" it sounds like it is coming from the right rear of the vehicle. Does this sound like anything familiar to anyone? What do you think it is, and what can be done to correct this?
