Axle Shaft Assembly: Description and Operation

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 can be removed without removing the hub.

NOTE: The hub uses a cartridge-type seal that must be installed new 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.
