ive read that it could be the steering box needs to be tightened. I have also read that the ball joints could be the problem. I have the same issue and havent figured out whats wrong. But I havent started shaking things down yet either.
Hey all I just traded my 04 Silverado SS for a 03 Superduty. Its a a 7.3 4x4 CC SB with 65 k on it and need a lil tlc . It was tough to see my SS go but i think the SD will suit my needs more. Anyway ill be asking tons of questions :D
