I bought a pinion bearing at tha local parts store and was given tha wrong one. The one i installed had the yoke sticking out enough for the rearend to leak fluid. Thinking i hadnt torqued tha yoke nut down enough, i ended up crushing the bearing. Sooo, after getting another yoke, seal, and correct bearing, i have a "roaring" vibration at a steady cruise. A buddy told me i may of messed up tha race. Are there any sites that would give me step by step instructions on changing it? Or could one of you Malibu Gods help me? How hard can it be? Its a 10 bolt 7.5 with a Auburn posi and Richmond 3.55 gear/moser axles. Thanks!!!
