The Zumbrota Drivetrain RAA440-1387 is a professionally remanufactured complete rear axle assembly, built to high standards of precision and reliability. Each assembly undergoes thorough inspection for straightness, cracks, and surface wear, ensuring OEM quality. The remanufacturing process includes 100% inspection of internal parts such as ring and pinions, internal gears, clutches, and carriers. Bearings, seals, crush sleeves, pinion nuts, and shims are completely replaced. Gear patterns are checked for optimum tooth contact, and correct rolling torque and backlash clearance are set for proper setup, longevity, and noise reduction. Axle tubes are inspected and straightened to OEM specifications, and all housings are tested for surface wear and cracks. A hydro blasting and rinsing process restores cases to an OEM finish. Zumbrota Drivetrain, based in Zumbrota, Minnesota, has over 30 years of experience providing remanufactured drivetrain components for domestic and foreign passenger cars, SUVs, and light-duty trucks.
