hi every time i go over a bump or un even pavement i get a loose clunking sound under wheel wells on front both sides. its gettin to the point where i feel it a bit under my feet. and guy in back seat said the same. the truck has definatly been used.
your problem in the clunking is MOST likely worn sway bar links. BUT the left right movement when you jerk the tires is MOST likely tie rods outer. The movement on up down jerks could most likely be the lower ball joints. Either way your truck sounds like it needs the entire front end rebuilt.
