im doing a disc brake conversion and one spindle had needles out of the race. ok going to get a kit for that one, problem is that they both have the seals in behind the needle bearings. i figured thats how they went but it seems that the seal goes on after, the needle bearings are pressed in just enough to accept the little seal, ofcourse than if you ever took the spindle off the seal would pop off because of nothing holding it on . i have three spindles out here and they all have the seal on first then the needle bearing. are they all wrong.
