hey i need help from u guys i was riding 2night and my right side on my axle where the hub goes on the axle wore all the teeth off of it why

 

more than likley you dont have the axle nut tight and it just wore it off from the tourqe when you hammer the gas!! its a common mistake so get a new hub thats my answer

 

yep, usually when splines on axles or hubs wear out it's because something wasn't tight enough, which allows some slop in the splines, which eventually turns into a lot of slop, and eventually it strips out completely. If the teeth on the axle are bad you'll probably have to replace the axle and the hub, but usually you can get away with just replacing the hub, and torque it down like a **** this time.
