Got an older formula rear wheel. At high speed it was making a growling sound. Opened it up and found imperfections (pitts) on the inner bearing race (the one used to preload the bearings). Does anyone know any way to fill those pitts reliably or am I stuck with buying a new hub?

well if you are daring you could try to fill it up with JB Weld and sand smooth. I think you might be in for getting either a new race or a new hub.

I filled the pits in with a steel and glass repair epoxy. Similar to JB weld but it has a much harder surface when dry. JB tends to be somewhat porus. I'll be filing it down tonight. Hopefully it works.

Keep posting about this. I've never heard of somebody trying to repair a bearing race.

New ball bearings might be in order, though I am cautious of recommending you spend any more money on that hub. Hate to be a negative nancy, but it's probably toast.
