Zumbrota Drivetrain meticulously rebuilds each axle assembly to high standards, ensuring precision and reliability. This process involves thorough inspection of all components, including the ring and pinion gears, internal gears, clutches, and carriers, for any signs of wear or damage. All bearings and seals are replaced with new ones. The gears are carefully inspected for optimal tooth contact patterns, and correct rolling torque is set using inch-pound measurements. Proper gear backlash is established to guarantee adequate gear lubrication and quiet operation. The axle tubes are also inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process to prepare internal and external parts, setting a benchmark for axle assembly remanufacturing. This specific assembly features a 3.73 gear ratio, a 9.75-inch Ford-built ring gear, and is designed for rear drum brakes. It includes 12mm wheel studs and has wheel bearings with a 2.533-inch outer diameter. The axle assembly comes with a cover, but fluid is not included. The Hollander number for this unit is 435-232F-P. This remanufactured axle assembly is intended for the 1999-2000 Ford F-150 models.
