1979 f250 - my toe is off and my camber is really off (inside of my tires cuppin bad) get a shimmy and shake like elvis friggin presly at highway speeds (round 45 and 55). truck pulls hard to the left steerin wheel is extremely unaligned also due to the alignment. when i make left turns i hear "POP!" and when i hear bumps and sometimes drive straight i hear "clunk rattle pop clunk clunk rattle" is this failin ball joints or am i crazy... because when i jack it up my tire has no play!!!! my mechanic keeps tellin me to get centric ball joints or somethin i dont really know what they are. if it is the ball joints would replacein them alone fix my alignment problums?
