Loud Knock!!
Hey guys im new to the site. I have a 99 lariat and its been running like a dream since I bought it 6 years ago. All of a sudden I go to work and its running fine when I got off made a right out the parking lot I heard a loud knock from my rear like I ran something over and it had a slight pull to it. It continued to do it only when I turned so I parked it. Does anyone have any answers to why?
