The Zumbrota Drivetrain RAA440-146 is a remanufactured rear axle assembly designed for specific applications. Each unit undergoes rigorous inspection, including checks for straightness, cracks, and surface wear, with internal components like gears, clutches, and carriers meticulously tested for optimal performance.

This rear axle assembly features correct gear backlash for optimal lubrication and quiet operation, and the axle tubes are verified against OEM standards for straightness.
