Rear Axle Assembly 3.55 Ratio

The Zumbrota Drivetrain Reman Axle Assembly is a remanufactured rear axle assembly specifically designed for the 2000 Ford F-150. This unit comes with a 3.55 gear ratio and is built for the Ford 8.8-inch axle with rear drum brakes and Posi Traction differential. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, and requires checking the specific tag numbers (S862D, S869D) for exact compatibility. During the remanufacturing process, Zumbrota Drivetrain meticulously inspects all components. Tubes are straightened to OEM specifications, and housings are tested for surface wear and cracks. A comprehensive 100% inspection is performed on all internal parts, including the ring and pinion gears, internal gears, clutches, and carriers. To ensure optimal performance and durability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housings undergo a state-of-the-art hydro blasting and rinsing process to achieve an OEM finish, and precise rolling torque is established using inch-pound measurements for accuracy and extended lifespan. This axle assembly is built to order, with a lead time for production. A refundable core charge of $400 is applied at checkout and is returned upon receipt of your old, salvageable part. Zumbrota Drivetrain offers a 2-year warranty on this differential. Please consult the technical notes for specific details regarding the Ford 8.8-inch ring gear, rear drum brakes, and Posi Traction. Fitment should always be confirmed with the vehicle tag numbers.
