Thumping sound
Hello all. I just bought a used 2010 f150 xlt. Four door. V8. 80k mi. It runs great. One problem that bugs me. It makes a thumping sound when i take off from a stop sigb or when i stop. It came with these aftermarket riear air bags for ride height when a load is present. Could that be the problem?
