Remanufactured Axle Assembly 4.10 Ratio, 10.5" Ring Gear

The Zumbrota Drivetrain RAA435-1553C is a remanufactured complete axle assembly designed for the robust Dana 70 differential. This unit features a 4.10 gear ratio, a substantial 10.5-inch ring gear, and a 10-bolt cover, making it suitable for demanding applications. Specifically engineered for 1989 Dodge D350 and W350 pickup trucks with dual rear wheels (DRW) and Posi-Traction, this axle assembly provides enhanced traction. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which may need to be sourced separately. The remanufacturing process at Zumbrota Drivetrain adheres to high standards of precision and reliability. Each axle assembly undergoes a rigorous 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 meticulously inspected for tooth contact patterns and correct rolling torque using precise inch-pound measurements. The correct gear backlash is set to ensure proper gear lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, to prepare both internal and external parts. This thorough cleaning ensures that all housings are returned to an OEM finish and meet OEM standards for straightness. This comprehensive remanufacturing approach aims to deliver a dependable and durable axle assembly.
