Remanufactured Axle Assembly

The Zumbrota Drivetrain RAA435-2033B-P is a remanufactured axle assembly specifically designed for 1997-1999 Ford F-150 vehicles equipped with the 9.75-inch ring gear and a 3.08 gear ratio. This assembly includes a Posi Limited Slip Differential and is intended for models with rear disc brakes. Zumbrota Drivetrain emphasizes precision and reliability in their remanufacturing process. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. Internal components, including ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. To ensure optimal performance and longevity, all bearings and seals are replaced, and gears are meticulously inspected for proper tooth contact patterns and rolling torque, with backlash set to ensure quiet operation and correct lubrication. The remanufacturing process includes an exclusive hydro-blast rinse and sandblasting procedure for internal and external parts, followed by a proprietary shot-enticed deep cleaning. This rigorous process sets a high standard for axle assembly remanufacturing. The unit features a 9.75-inch ring gear, is Ford-built, and comes with a Hollander number of 435-233B-P. It is equipped with 12 MM wheel studs and has 2.533 OD wheel bearings. The axle type is semi-floating, and a cover is included, though fluid is not. Note that the unit is listed as having a 3.8 ratio and also 'Without Posi Traction' in the specifications, which may require cross-referencing with the 'Check Tag' instruction on the product title.
