Hey everyone, I've been snooping around here for a few months and finally decided to post. I have a clunking sound coming from the drivers side rear. It happens when the vehicle shifts its weight, around turns or bumps. i can't get the truck to make the noise by jumping up and down on the bumpers, and i've been to lazy to crawl in back while someone else is driving in order to pinpoint the noise. Has anyone else had this problem or any idea what it is. Thanks for any help.
