My grandson’s 2004 250ex left rear axle spins loosely inside that hub. Something is stripped and I’m hoping it is the hub splines and not the axle splines. Visually, I can’t tell but since the hub is softer metal, cheaper and easier to replace than a steel axle, that’s what I’m going to try first.

Anybody got experience here one way or the other? What did you replace? Axle or hub?

Many thanks,

Rick
