Even though I have new bike wheels on the way, I figure I should try and make the old ones work as good as possible for spare / winter use. Part of this involved disassembling the rear hub, cleaning it, and just generally being sure it’s okay. It was a bit sticky and wasn’t turning very smoothly, so I figured that maybe it had a bearing and/or race problem like the front wheel did.
After opening up the rear bearings I found that there was nearly a tablespoon of grease around the balls and sitting lumpily on the axel, with lots of it in places where it just wouldn’t do much beyond compacting and gumming up the works. Tomorrow (or maybe Sunday) after I get a properly sized cone wrench I’ll put the wheel back together and see how it works. The freewheel itself currently seems fine so I don’t need to touch that, but the wheel bearings themselves were definitely needing some work.
