Reman Rear Axle Assy 3.45 Ratio 230mm Ring Gear

The Zumbrota Drivetrain Reman Rear Axle Assy (RAA440-1461) is a meticulously rebuilt rear axle assembly, engineered as a direct-fit replacement for 2011-20 Dodge Durango and Jeep Grand Cherokee models. This unit is specified for vehicles equipped with an Independent Rear Suspension (IRS) and lacking an electric locking differential, featuring a 3.45 gear ratio and a 230mm ring gear. Each axle assembly undergoes a rigorous remanufacturing process to meet high standards of precision and reliability. This includes thorough inspection of housings for straightness, cracks, and surface wear. All internal components, such as ring and pinions, gears, clutches, and carriers, are fully inspected and tested. To ensure optimal performance and longevity, all bearings and seals are replaced, and gears are inspected for correct tooth contact patterns and rolling torque, with backlash precisely set for proper lubrication and quiet operation. The housings are subjected to a comprehensive cleaning process involving hydro-blasting and sandblasting, returning them to an OEM finish. Units are shipped in high-density plastic totes to minimize in-transit damage. This remanufactured axle assembly comes with a 2-year limited warranty, underscoring Zumbrota Drivetrain's commitment to quality and durability.
