Alright, I'm convinced not to seal it up yet, but what next? Drive looks good, but I can't find any reference material on what to do with the diagonal coast pattern.

I retorqued the caps to 80 and the ring gear bolts to 110 and ran it again with no change. Rotation is smooth all the way around, and has proper pinion and carrier preloads dragging. I'm using a strap wrench around the spool wedged against the case. It takes about 30 - 40 ft-lb to turn the pinion and slip past the wrench. Pattern is slightly wider, but same position and shape.

Moving the pinion deeper seems to move the drive towards the heel and the coast towards the toe. I don't know if I want to do that...
