Dana 70 Rear Axle Assembly 3.55 Posi

The Zumbrota Drivetrain RAA435-1778A is a remanufactured Dana 70 rear axle assembly, specifically designed for 1994-1999 Dodge Ram 2500 4x4 models equipped with staggered shocks and a Posi Limited Slip Differential. This assembly features a 3.55 gear ratio, ensuring appropriate torque transfer for 4-wheel drive applications. Each axle assembly undergoes a rigorous remanufacturing process to meet high standards of precision and reliability. Zumbrota Drivetrain meticulously inspects all internal components, including ring and pinions, internal gears, clutches, and carriers. Critical wear items such as all bearings and seals are replaced with new parts. The gear setup involves inspecting for optimal tooth contact patterns, setting correct rolling torque using inch-pound measurements for precision and longevity, and ensuring proper gear backlash for quiet operation and lubrication. Furthermore, the axle tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, setting a high standard for remanufactured axle assemblies. This comprehensive approach ensures that the final product is built to last and perform reliably.
