Currently on my fourth relatively large TT And I do my own wheel service. Fortunately there is a store nearby that specalizes in bearings, seals and surrounding stuff.I was told last time I was in there that Timken bearings are now made in China. In any event, after seeing a bearing failure (somebody else) in a rest stop, I don't EVER want be in that situation. The inner bearing was fused to the axle stub. Bearings, races and good grease don't cost that much. I grease every year and just replace the whole shebang every three years. There is a video at Dexter axle's web page that lays out the whole procedure including bearing preload procedures.
