On my 235 I was unable to prevent the inner race of the wheel bearings from
rotating on the axle, even with what seemed to be an extreme amount of
preload. This occurred on both the mains and the nose wheel, and caused deep
wear in the GM31 spacers.

The solution which has worked well for nearly ten years, was to make a
spacer from a piece of tubing which fits over the axle and bears against the
inside surface of the inner race of the wheel bearings. My recollection is
that the spacer is about an 1.5" long. Now when the axle nut is tightened,
it squeezes the bearing inner races against this spacer rather than loading
the bearing. It took a bit of "test and file" to make the spacer the right
length to take the play out of the bearings without adding too much preload.
