I have a 'clunk', anyone else have one?
 

I have kind of a klunk which sounds like it behind me and only on certain kinds of bumps. Shock, exhuast, not sure. Anyone have anything similar? TIA.

Sounds like your out of radiator grease.............................. I just kid, Seriously, does your clunk sound like a metal chatter over bumps under 40 mph or slower?
if so, could be rear control arm (track arm).

Could you discribe the noise in better detail?

that sounds like it
 

can't describe it any better than you have. Glad mine's certified - any reason to rush in to get it looked at?

Yeah i'd take it into the dealer for repair is its covered under warranty, that control arm takes about 1.5 hr to replace but cost about 300+ bucks each.
