I have a problem with the drivers side door latch on my Challenger. There is a hard rubber bumper on the latch that has developed a flat spot. If the bumper is rotated such that the arm that strikes this bumper hits the flat spot, the latch does not work properly. I have to use the inside and outside handle to open the door. I have rotated the bumper so the flat spot is not contacted, but it always rotates back to the same spot. Has anyone else had this problem, if so how did you fix it? Or does anyone have a drivers side latch assembly that does not have a flat spot on the bumper?
