Dana 30 3.73 Gear Ratio Rear Axle Assembly

The Zumbrota Drivetrain RAA434-1810C is a remanufactured complete axle assembly engineered to meet high standards of precision and reliability. This Dana 30 axle assembly comes with a 3.73 gear ratio and is designed for specific Jeep Grand Cherokee models. This unit is built for 1993-1998 Jeep Grand Cherokee vehicles, specifically those equipped with the NP249 transfer case. It features a U-joint style pinion yoke and U-joint style axles, ensuring compatibility with the original equipment. The assembly undergoes a rigorous remanufacturing process, including thorough inspection of housing for straightness, cracks, and surface wear. All internal components, such as ring and pinions, gears, clutches, and carriers, are inspected and tested. Zumbrota replaces all bearings, seals, crush sleeves, pinion nuts, and shims. Gears are meticulously inspected for optimal tooth contact patterns and set to correct rolling torque using inch-pound measurements for precise setup and longevity. Correct gear backlash is also set to ensure proper lubrication and quiet operation.
