Complete Axle Assembly Dana 30 3.73 Ratio

The Zumbrota Drivetrain RAA434-1894H is a remanufactured complete axle assembly designed for the Dana 30 differential. This unit is specifically built for the 1998 Jeep Grand Cherokee, featuring a 3.73 gear ratio and compatible with the 242 transfer case. It includes the main housing and all internal components, but excludes axles, ball joints, spindles, steering components, and brakes. Zumbrota Drivetrain emphasizes quality and reliability in their remanufacturing process. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal parts, including ring and pinions, gears, clutches, and carriers, are inspected and tested. To ensure longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. Gears are meticulously checked for tooth contact patterns and rolling torque, with precise backlash settings for proper lubrication and quiet operation. The remanufacturing process includes a rigorous cleaning regimen. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This ensures that all housings are restored to OEM specifications for straightness and are tested for surface wear and cracks, setting a high standard for remanufactured axle assemblies.
