Installed new pinion gear and bearings. spins freely. I can se the front edge of the pinion retainer ring through the locking bolt holes. Placed the J-4050 spacer tool in, still no issues. Thread the bolts in to touch, bottom bolt first and still spins. As per Deves, remove the J-4050 tool. begin to put ANY pressure on the retainer bolts and it binds the pinion gear as well as drawing it in so that the J-4050 no longer slips between the rear pinion bearing and the gear. The retainer ring looks to be seated evenly when looking through all 3 bolt holes. Any one have an opinion or experience? First time attempting this, Been at it a few hours and patience has gotten thin. Any help is greatly appreciated.
