I understand that the spacer locks the inner races of the bearings and stub
shaft together to prevent and slipping of races on the stub shaft. The
minor play is up and down and appears to be the outer bearing. The inner
race and the outer bearing seem to line up perfectly. Not sure if under the
360# of torque + a little heat from running the bearing may slightly swell
the inner race to take up the minor wiggle? I know the Germans have some
kind of magical engineering formulations that at first seem questionable
but end up right on the money 😉

That spacer being less than 42.8mm in my experience has shown to

lbs. All new spacers are all 42.8 mm long, maybe they made them that way
for a reason. I certainly have a pile of used ones that are less than 42.8
mm. So….something wore them down and after installing new bearings and new
spacers I get no rock from the wheel when trying to move it back and forth
using the 12 and 6 o’clock hand positions on the wheel.
