Remanufactured Axle Assembly 4.11 Rear Drum Brakes

The Zumbrota Drivetrain RAA435-2028A is a remanufactured axle assembly specifically designed for the 8.8" Ford F-150 model year 2000. This unit features a 4.11 gear ratio and is configured for rear drum brakes, excluding Posi Traction. Each axle assembly undergoes a thorough inspection process. This includes checking for straightness, cracks, and surface wear on the axle tubes. Internally, all components such as ring and pinions, internal gears, and clutches are meticulously inspected and tested. Zumbrota replaces all bearings and seals, and ensures gears are set for optimal tooth contact patterns and correct rolling torque, utilizing inch-pound measurements for precise setup and longevity. Proper gear backlash is established to guarantee adequate gear lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This method sets a high standard for the remanufacturing of axle assemblies. The assembly includes the axle cover and features an 8.8-inch ring gear, with components being Ford-built. The Hollander Number for this unit is 435-228A.
