hey guys so when i go down curbs or hit speed bumps at slow speeds i notice a clunk noise....i thought it was loose cradle bolts so i tightened them and its still there....i had my cradle dropped by a shop recently and i was wondering do you guys think this noise could be caused by loose motor/tranny mount bolts? i also have poly upper mounts but i dont see them causing this clunk noise and it sounds like its coming from under the motor...whats your insight on this?
