Check your ball joints!

Old test for shocks, push down on the hood near the tires, the truck should only bounce once or so. If shocks are bad that side will seem to float , (hard to describe) Need large person or several to do on heavy duty truck. (thinky?)

But ball joints will bang if hitting bumps, jack the truck up so the tire is off the ground,(safely) and try shaking the tire/wheel up and down
