The SEALED CARTRIDGE bearings used sometimes are held against a shoulder on the axle, by a nut that is sometimes NOT jammed with a jam nut... those things are a pain to deal with, then toss in some bunged up threads on the axle for SERIOUS hassles....... and the freehubs readily fail on that type also.

the truly sad part is that the BMX people that insist on the 9 tooth freehub setup usually have no idea WHY they want that 9 tooth, except so that they can ride a bike capable of tricks, yet rarely can they DO those tricks... or they saw it on a hero's bike, so it's gotta be great for them...... they then over-tighten the chain tension after it first needs adjustment... the rest of the process is waiting for the hub to grenade.... the BB takes quite a beating too...

there are a few riders that took time to learn about frictional losses, proper chain tensions, and correct bearing adjustment.... a few..... their hubs last much longer!

a 9 tooth freehub hub sells for $80 and up... mostly UP.

look up the word "bearing".
