Im new to these forums, Any advice would be great! Thanks in a advance . Ive had a clunk in the Pass rear of my car when hitting big bumps. I did the obvious and replaced both rear knucklesAnd the clunk still remained. I did an entire inspection of my rear suspension and could not find and obvious problems. I read somewhere of a person having to change out the rear door actuator because it may cause the rear door to slam while going over bumps. Has anybody else had this problem in the past?
