Description

The Zumbrota Drivetrain RAA435-1997A-P is a remanufactured axle assembly designed for Chrysler 8.25-inch differentials. This unit comes equipped with a 3.55 gear ratio and a Posi Traction limited-slip differential, specifically for 4x4 vehicles. Each axle assembly is rebuilt to rigorous quality standards, ensuring precision and reliability. Zumbrota Drivetrain meticulously inspects all internal parts, including ring and pinions, gears, clutches, and carriers, for any signs of wear or damage. As part of the remanufacturing process, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new components. Gears are carefully inspected for optimal tooth contact patterns and correct rolling torque, established using inch-pound measurements to guarantee precise setup and longevity. The correct gear backlash is also set to ensure proper lubrication and quiet operation. Axle tubes are inspected and straightened to meet OEM specifications. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process, to prepare all internal and external parts, setting a high standard for remanufactured axle assemblies.
