Remanufactured Axle Assembly, 4.11:1 Ratio

The Zumbrota Drivetrain RAA440-1369C is a remanufactured axle assembly designed for the Dana 30 differential. This unit features a 4.11:1 gear ratio and an open differential carrier type, specifically engineered for 2002-2005 Jeep Liberty models with the 2.4L engine. Zumbrota Drivetrain emphasizes precision and reliability in their remanufacturing process. Each axle assembly undergoes a rigorous inspection for structural integrity, including checks for straightness, cracks, and surface wear. Internally, all components such as ring and pinions, gears, clutches, and carriers are meticulously inspected and tested. To ensure optimal performance and longevity, all bearings and seals are replaced, and the gears are checked for proper tooth contact patterns and rolling torque, with backlash set for quiet operation and adequate lubrication. Zumbrota employs a proprietary cleaning process that includes hydro-blasting, sandblasting, and a deep cleaning procedure. This state-of-the-art method restores housings to OEM finish and prepares internal and external parts for remanufacturing. All housings are tested for wear and cracks, and 100% of internal parts are inspected. Bearings, seals, crush sleeves, pinion nuts, and shims are all replaced as part of the remanufacturing process. The correct rolling torque is established using inch-pound measurements for precise setup and extended durability.
