I think I might need to rebuild mine. My truck came to a screeching halt yesterday in the middle of a trrip from NYC to Baltimore. It wouldn't go forward until I reversed, then it drov forward ok. As I got back on the highway it didn't seem right, very shaky, but the wind was blowing hard so I'm not quite sure how much was from the truck. It also seemed like it wanted to lock up again a few times but it didn;t happen. I also had to pump the brakes once before they would work after driving like this.
Are there any good sources for hub rebuild parts or a kit? I searched through the forum and it seems highly likely the hubs is the culprit.
