It's been a long time. The bearing race seated okay after it got past the ridge. IIRC the ridge was just to the outside of the bearing race seating area. > I've had bearings seize and they removed metal & made the replacement > bearing race loose on the spindle, not the other way around.

It had a little too much play to be a quality bearing. Next time I grease the wheels I'll try a Mercedes bearing. It could have been that the U.S. mfg. bearings were a little tighter although that seems unlikely.
