Wheel Hubs and Bearings
Wheel hubs and bearings consist of:
-
removable rotor from hub on Single Rear Wheel (SRW) vehicles.
-
unitized rotor and hub on Dual Rear Wheels (DRW) vehicles.
-
cartridge-type hub seal.
-
two opposed taper roller bearings supporting the hub.
-
ratcheting nut tabbed to a slot on the spindle.
The full-floating rear axle features disc brakes. The disc brake calipers must be removed to remove the rotors and hubs. The rotor on the SRW design
can be removed without removing the hub. DRW axles require that the hub and rotor be removed as a unit.
Both DRW and SRW hubs feature a cartridge-type seal that must be installed new any time the hub is removed.
The rear hub is supported or floats on the axle spindle on 2 opposed tapered roller bearings. It is retained on the spindle by a ratcheting nut that is tabbed
to a slot on the spindle.
