Remanufactured Axle Assembly Dana 70 3.55 Ratio 2WD

The Zumbrota Drivetrain RAA435-1764A is a remanufactured axle assembly engineered for the Dana 70 rear axle, specifically built for 1994-1999 Dodge Ram 2500 2WD models equipped with staggered shocks and a 3.55 gear ratio. Each Zumbrota axle assembly undergoes a rigorous remanufacturing process to ensure precision and reliability. The housing is inspected for straightness, cracks, and surface wear, while all internal components—including ring and pinions, internal gears, clutches, and carriers—are thoroughly inspected and tested. To guarantee optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are meticulously inspected for proper tooth contact patterns and correct rolling torque, with backlash set precisely for quiet operation and adequate lubrication. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This advanced cleaning method sets a high standard for axle assembly remanufacturing, restoring cases to an OEM finish. This assembly is built to order and ships when ready, backed by a 2-year limited warranty.
