I was hoping someone could help me with a problem I have had with my 2003 lightning for a while. When backing up and turning at the same time the front end makes a very loud popping sound. The sound comes from the left side if I'm turning right and right side if turning left. I dropped off the truck at the dealer to get it checked and they could not find anything wrong with it, yet the sound is very loud and I know there has to be something wrong. Please reply or email me if you have any info on the matter. Any help will be truly appreciated.
