Am I interpreting the markings correctly that my outer wheel bearing
has been seizing occasionally and that the inner race has been
spinning on the spindle?

I am planning to replace the outer bearing now, though the new bearing
is still a little loose on the spindle.  Is there anything I can do
today to help prevent the problem?  Is the only permanent fix a new
spindle/upright?

I'm planning to do new LBJs, pads, bearings, and rotors next year, but
It would be great if I can make it 'til then on this spindle.

Any advice I can get in the next few hours would be awesome.

(I got here after noticing a funny sound at ~30mph on rough roads, and
some bearing play.)

Thanks all,

Alex
