Thanks, Jur!

I'll be working on the hub this weekend. I'm afraid I won't be able to re-use all the parts, especially this one, which I found when I took the left cone off a couple days ago:
It was mixed with filthy grease, so at first I thought it was just dirt... but after cleaning it up a bit I decided it was a ball retainer (but am willing to listen to other theories). Did I mention the bearings were running rough?
