Remanufactured Axle Assembly 3.08 Ratio Rear Disc

The Zumbrota Drivetrain RAA435-2033B is a remanufactured axle assembly specifically designed for 1997-1999 Ford F-150 models equipped with a 9.75-inch ring gear, a 3.08 gear ratio, and rear disc brakes. This unit undergoes a comprehensive rebuilding process to ensure precision and reliability. Each axle assembly is meticulously inspected for straightness, cracks, and surface wear. Internal components, including the ring and pinions, internal gears, clutches, and carriers, are thoroughly examined and tested. Zumbrota replaces all bearings and seals, and inspects gears for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precise setup and longevity. Proper gear backlash is set to ensure adequate lubrication and quiet operation. The axle tubes are also inspected to meet OEM standards for straightness. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process, to prepare parts for remanufacturing. Key specifications include a 9.75-inch ring gear, Ford-built components, a 3.08 gear ratio, rear disc brake compatibility, 12 MM wheel studs, 2.533 OD wheel bearings, and an open differential (without Posi Traction). The axle type is semi-floating, and the cover is included. Note that fluid is not included with this assembly. This specific model is designated as Hollander No. 435-233B. It is crucial to check the tag on your existing differential to ensure compatibility, as indicated by the '*Check Tag*' notation in the product title.
