Alright Audi Lovers, need some help....

I've got a 2001 Audi A6 2.7T... and every time I hit bumps (even the smallest ones) at low speeds, it sounds like my back seat/seatbelt is squeaking and creaking... any advice as to what I should try to alleviate this issue? I really would like a quiet ride...

Please help!

 

Guess I got to anxious to solve the issue... did a search on the forums... found some answers.. will try to check the folding seats and possibly do some Lubing!
