Remanufactured Axle Assembly, Dana 70, 4.56 Ratio

The Zumbrota Drivetrain RAA435-1553D-P is a remanufactured complete axle assembly specifically designed for Dana 70 axles. This unit is built to the highest quality standards for precision and reliability, ensuring optimal performance for your vehicle's drivetrain. This assembly features a 4.56 gear ratio, a 10.5-inch ring gear diameter, and a 10-bolt cover. During the remanufacturing process, all internal components, including ring and pinions, internal gears, clutches, and carriers, are thoroughly inspected and tested. To ensure longevity and proper function, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. Zumbrota Drivetrain employs a rigorous remanufacturing procedure. Axle tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks. The internal components undergo a 100% inspection. Gears are meticulously checked for optimal tooth contact patterns and correct rolling torque using inch-pound measurements, with backlash set precisely for proper gear lubrication and quiet operation. The housings are cleaned using an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, setting a high standard for axle assembly remanufacturing. This particular axle assembly is designed for 1989 Dodge D350 and W350 models with gas engines. It specifically includes the Posi Traction differential but does not include hubs, brakes, backing plates, or axle shafts.
