The teeth look all uniform, albeit highly corroded. I dont know if they are worn down or not, since i dont have a spare to compare it to. If this issue is caused by an excessive spacing gap, is my only option to get a new hub, and hope the teeth close that gap, or is there something I can "rig" or machine to close the gap.
