Dana 50 Front Axle Assembly 3.73 Ratio SRW

The Zumbrota Drivetrain RAA434-1351B is a remanufactured Dana 50 front axle assembly, meticulously rebuilt to meet stringent quality, precision, and reliability standards. This assembly is designed for 1999-2001 Ford F250 and F350 models equipped with single rear wheels (SRW) and rear wheel ABS. Each axle assembly undergoes a thorough inspection for straightness, cracks, and surface wear. All 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 inspected for correct tooth contact patterns and proper rolling torque, with precise setup using inch-pound measurements. The gear backlash is set correctly to guarantee proper gear lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This comprehensive remanufacturing approach sets a high standard for axle assembly restoration. This specific unit features a 9-inch ring gear, a 3.73 ratio, and a 13mm thick hub flange, and is exclusively for single rear wheel applications with rear wheel ABS.
