geras are a matched set. i wouldnt advise replacing one without the other!!! if you repllace both, grind the old bearing as you described without installing the crush sleeve till you have it right. then tear down and re assemble for the last time as you should!!!
I understand that. New gears are tested and run by the vendor and they need to match. I need to take out a brand new 3.73 set and put in 3.08 or 3.42. The rest of the parts in the axle are supposed to be new, so I want to save them. I don't have an H stand press, much less a slide hammer. I don't have an old bearing. Should I buy a new one and grind the inside to sacrifice for the project?
