  • What's this knocking sound?

    I have a knocking sound coming from the rear when I go off of bumbs. I thought it might be a hanger but I checked them all and they look fine. It seems the knocking noise occurs when the car has been running for a bit. I can not duplicate the sound when the car is cool. Any ideas?

    when you say knocking... is it a loud "clunk" when you hit the bump and done or is it, you hit the bump and there is a clunk, clunk, clunk, clunk sound?

      I get a loud "clunk" from the back right when hit a bump with weight in the back of my car. I've got new shocks on the way though so i hope that might fix it?

        2 possibilities one is the rear shock either loose or just bad other option is your exhaust hitting the frame or the heat shield on your muffler to gas tank.
