Section 05-02A: Axle, 10.25-Inch Ring Gear | 1996 F-250 Light Duty (Semi-Float), F-250 HD and F-350 (Full-Float) Workshop Manual |
F-250 and F-350 vehicles use the rear anti-lock braking system. The system is designed to automatically reduce brake pressure when brake lockup is detected during braking. The system features an anti-lock speed sensor ring that is pressed on the differential case (4204) behind the ring gear. If the anti-lock speed sensor ring is removed, it must be discarded and replaced with a new one. The anti-lock speed sensor ring works in conjunction with the rear brake anti-lock sensor retained in a bore at the top of the carrier and fastened by one bolt. There is a space provided between the ring gear and anti-lock speed sensor ring for measuring the ring gear backface runout. For more information on the Rear Anti-Lock Brake System, refer to Section 06-09A.
