Ok, I know zero about hubs..well, actually I did learn a little taking one apart and screwing it up today. It all sorta came apart when I removed it. On a stock hub, are there 2 springs? I assume the gear needs to be attached to the rest of the lock/unlock mechanism, but mines not and I'm guessing that there is only one spring and it is broken (hence the 2 spring question). I tried to reassemble it, and I can get the mechanism to work, but the gear isn't attached so I can't see how it would disengage in the free position. I really can't see what would connect the gear to the rest of the mechanism to pull it back to "Free" Next step is CAREFULLY pull the other one off and take a look.
