Remanufactured Axle Assembly 3.73 Ratio Ford 10.5 Inch SRW

The Zumbrota Drivetrain RAA435-159A is a remanufactured complete axle assembly, meticulously rebuilt to meet high standards of precision and reliability. This unit is designed for the Ford 10.5-inch ring gear, featuring a 3.73 gear ratio suitable for single rear wheel (SRW) applications. It is specifically manufactured without posi-traction. During the remanufacturing process, each axle assembly undergoes 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 longevity and optimal performance, all bearings and seals are replaced, and gears are inspected for proper tooth contact patterns and correct rolling torque. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process. This ensures internal and external parts are cleaned to OEM standards, setting a benchmark for axle assembly remanufacturing. Gears are set to precise backlash specifications for proper lubrication and quiet operation, and axle tubes are inspected to ensure they meet OEM standards of straightness. This specific axle assembly is intended for 2008-2010 Ford F-250 and F-350 models with the 5.4L engine. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately.
