Remanufactured Complete Axle Assembly for Dana 70HD 3.73

The Zumbrota Drivetrain RAA435-1659B-P is a remanufactured complete axle assembly specifically designed for the Dana 70HD differential. This unit comes equipped with a 3.73 gear ratio, a robust 10.5-inch ring gear, and a 10-bolt cover, making it suitable for dual rear wheel applications and featuring a G80 Posi-Traction limited-slip differential. Zumbrota Drivetrain emphasizes precision and reliability in its remanufacturing process. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. Critical internal components, including the ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. Gears are evaluated for optimal tooth contact patterns and correct rolling torque, with backlash precisely set for proper lubrication and quiet operation. The remanufacturing process includes advanced cleaning techniques. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process for both internal and external parts. This ensures housings meet OEM standards for straightness and provides a finish comparable to new components. This assembly does not include hubs, brakes, backing plates, or axle shafts. This remanufactured axle assembly is specifically designed for 1990-1991 GM 3500 Pickup trucks equipped with the Dana 70HD differential and dual rear wheels.
