Remanufactured Axle Assembly Dana 60 3.73 Gear Ratio

The Zumbrota Drivetrain RAA435-181A-P is a remanufactured axle assembly engineered for the Dana 60 differential, offering a 3.73 gear ratio and semi-floating axles. Each axle assembly is meticulously rebuilt to exacting quality standards. Zumbrota Drivetrain subjects every unit to a comprehensive inspection process, verifying straightness, detecting cracks, and assessing surface wear. Internally, all components, including ring and pinions, gears, clutches, and carriers, are thoroughly inspected and tested. To ensure optimal performance and durability, all bearings and seals are replaced. Gears are examined for perfect tooth contact patterns and precise rolling torque is set using inch-pound measurements, crucial for longevity and quiet operation. To guarantee proper function and a quiet ride, correct gear backlash is precisely set, ensuring adequate gear lubrication. The axle tubes are inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts, followed by a proprietary deep cleaning process, establishing a benchmark for remanufactured axle assemblies. This assembly includes the axle cover but does not include differential fluid. It features a 9.75-inch ring gear size and is identified by Hollander Number 435-181A-P.
