Remanufactured Dana 70 Rear Axle w/ 3.42 Posi Limited Slip

The Zumbrota Drivetrain Reman Axle Assy is a comprehensively remanufactured Dana 70 rear axle assembly, built to restore reliable performance to your heavy-duty truck. This unit comes equipped with a 3.42 Posi Limited Slip Differential (LSD), enhancing traction and capability for towing and hauling. Each axle assembly undergoes a rigorous remanufacturing process. All tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks. Internals, including the ring and pinion, gears, clutches, and carrier, are 100% inspected. Critical wear components such as bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housings are then cleaned using a state-of-the-art hydro blasting and rinsing process to achieve an OEM finish. Precision setup is ensured through correct rolling torque establishment using inch-pound measurements for longevity and setup accuracy. This specific assembly is designed for 1990-1991 Chevrolet/GMC 3500 Pickup models equipped with dual rear wheels (DRW) and featuring specific VIN codes R and V, indicating the presence of the Dana 70 axle.
