I am reassembling the axle and am up to the hub/ disc assembly. when i install the hub and disc and tighten down the nut and then spin the hub, itspins out of true. like the bearings arent seated properly. its not the disc warped and i tried my other hub assebly so its not that. it cant be a bent spindle, that wouldnt cause runout. i cant for the lifge of me figure it out. there is 1 seal i didnt use. it didnt state to in the manual, i thought it might be one for liek a ford??? i dont think that could cause this but who knows. its a red one if that helps. the way i have it now from inner c out is 1 seal, bearing, race, then on the outside of the hub, race, bearing, washer, nut. Hekp p.s its drw new rotors, bearings, seals. the races looked ok, but could the old races be causing the problem?
