Section 05-02B: Wheel Hubs and Bearings, Rear, Ford Full-Floating Axle | 1996 F-250 HD and F-350 Vehicles Workshop Manual |
The full-floating rear axle features brake drums that are mounted outboard of the rear hub (1109). Therefore, when brake inspection or replacement is required the rear hub need not be 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.
NOTE: If, for any reason, the rear hub is removed from the spindle, the old hub seal must be removed and a new hub seal installed.
