Wheel Hubs and Bearings

Wheel Hubs and Bearings
The full-floating rear axle features disc brakes. The disc brake calipers must be removed to remove rotors and hubs. The rotor on the single rear wheel design can be removed without removing the hub. Dual rear wheel axles require that the hub and rotor be removed as a unit.
Both DRW and SRW hubs feature a cartridge Ape seal that must be replaced anytime the hub is removed.

The rear hub is supported or floats on the axle spindle on two opposed tapered roller bearings. It is retained on the spindle by a ratcheting nut that is tabbed to a slot on the spindle.
