Your last photo only shows the NDS, and it shows zero clearance, which may be correct, but we can't see the DS.

If I were there, I'd disassemble everything, and assemble each bearing on the bench, getting visual confirmation the spindle race is contacting the bearing correctly in the cup, and noting the clearances mentioned above.
