Rear Axle, Dana Model 80 Full-Floating
Full-Floating Axle, Model 80
Section 05-02D: Axle, Rear, Dana | 1996 F-Super Duty Workshop Manual |
Model 80 rear axles (4001) are equipped with full-floating axle shafts (4234), meaning loads are supported by the axle housing. These rear axles have an integral-type axle housing, hypoid gear design with the centerline of the pinion set below the centerline of the ring gear. The axle shaft is retained by bolts attached to the rear hub (1109). The rear hub rides on two bearings at the outboard end. The axle housing consists of a cast center section with two steel tubes. A stamped axle housing cover (4033) uses silicone rubber or equivalent as a gasket. A metal tag, attached to axle housing by two cover bolts, is stamped with the gear ratio and part numbers.
