Dana 30 3.55 Ratio Axle Assembly

The Zumbrota Drivetrain RAA434-1928D is a remanufactured axle assembly specifically designed for the Dana 30 differential, featuring a 3.55 gear ratio and ABS compatibility. This unit is intended for left-hand drive applications. Zumbrota Drivetrain rebuilds these axle assemblies to stringent quality standards, ensuring precision and reliability. The process involves a comprehensive inspection of the differential's housing for straightness, cracks, and wear. Internally, all components such as ring and pinions, gears, and clutches undergo thorough testing. Crucially, all bearings and seals are replaced with new parts. The gears are meticulously inspected for optimal tooth contact patterns and set to the correct rolling torque with precise backlash adjustments to guarantee proper lubrication and quiet operation. Zumbrota utilizes an advanced cleaning procedure that includes hydro-blasting and sandblasting for both internal and external parts, followed by a proprietary shot-peening deep cleaning process. This ensures a superior finish and prepares the components for longevity. The axle tubes themselves are also inspected to meet OEM standards for straightness. This specific assembly is designed for Jeep Cherokee models from 2000-2001 and features a 7.12-inch ring gear diameter.
