Dana 70 Posi Traction Differential Assembly

The Zumbrota Drivetrain RAA435-1777A-P is a remanufactured complete axle assembly. This unit is built around a Dana 70 differential, featuring a 10.5-inch ring gear and a 10-bolt cover pattern. It is specifically designed for 4x4 drivetrain configurations and comes equipped with Posi Traction for enhanced performance. Each axle assembly undergoes a comprehensive remanufacturing process by Zumbrota Drivetrain to meet high standards of precision and reliability. This includes thorough inspection of all internal components such as ring and pinions, internal gears, clutches, and carriers. To ensure optimal performance and longevity, all bearings and seals are replaced, and gears are meticulously inspected for proper tooth contact patterns and correct rolling torque, set using inch-pound measurements. The axle tubes are also inspected and straightened to OEM specifications. Zumbrota Drivetrain utilizes an exclusive cleaning procedure, involving hydro-blast rinsing and sandblasting, followed by a proprietary shot-enticed deep cleaning process. This ensures that all internal and external parts are thoroughly cleaned, bringing housings back to their OEM finish and setting a high standard for remanufactured axle assemblies. This specific assembly is manufactured through 9/23/93. It is important to note that this product is sold as an assembly only and does not include hubs, brakes, backing plates, or axle shafts.
