Guys, I'm trying to get the old axle off the 250r, how do you get the disk break HUB off of the axle?

 

The rear axle locknuts are left handed threads so go clockwise to loosen both locknuts. Loosen the outer locknut and screw it IN toward the brake disc until the snap ring is visible. Once you remove the snap ring from the axle, you can slide the brake hub off.
