Agreed the bearings are very generously sized and should last forever. Monstrous by modern standards.
The outer ring of the inner race shoud not only be a very snug fit in the housing but should be lightly pinched when all is assembled. If the gasket is too thick and/or the concave steel seal washer omitted the race will not be gripped and work loose. I dont know if hubs vary much but all can be checked with a vernier calliper depth gauge. Ideally should be tight in both hub halves but if well clamped one will do. Some resort to Loctite but many hubs have been distorted even without that complication. Perhaps just treat one half.
Many attempt to assess bearings by tilt but this can vary markedly. Radial clearance is the real factor, not easy to assess.
Normally races are only considered failed when tracks or balls are pitted.
