Can anyone recommend some good online tutorials for repairing/maintaining a flip-flop hub? I just got a bike on craigslist (Raliegh One-way) and it's starting to make a rattling or knocking type of noise while pedaling, regardless of how lightly I pedal. The noise seems to be coming from the freewheel, but may be the hub. I'm not experienced with this type of maintenance, but I'd like to learn.
I tried to take a look last night, but got stuck. After getting the outer nuts off, I saw it was a 4-notch freewheel, which I don't have a removal tool for. I'm assuming that once I get that, I can just use the removal tool and chain whip to get the freewheel off. What then? Is there a way to service the freewheel, or is that something I'll need to replace?
Also, if the problem is the hub, can that be serviced, or does it need to be replaced? I'm not sure if I have a cartridge-type of hub or not. Once I get the freewheel off, is removing the axle and inspecting easy to do?
