Are those the under panels by the rocker? If so mine are off and sounds still remain. Took them off for running board install and did not want to cut them
Have the same over any bumps , dips , driveway, and this weird clicking if you go down hill hit the brakes while turning, it makes a clicking sound. I live on a hill side with narrow streets, and twice while going down hill I had to hit the brakes around a blind turn as a neighbor was coming up...
