8.8-Inch 3.73 Ratio Axle Assembly

The Zumbrota RAA435-1556J is a remanufactured axle assembly, engineered for durability and precision. This unit features an 8.8-inch ring gear and a 3.73 gear ratio, specifically designed for 1991-1994 Mazda Explorer and Navajo models equipped with ABS. Zumbrota Drivetrain prioritizes the highest quality standards in rebuilding these axle assemblies. Each unit is subjected to rigorous inspection, checking for straightness, cracks, and surface wear. Internal components such as ring and pinions, gears, and carriers are fully inspected and tested. To guarantee optimal performance and longevity, all bearings and seals are replaced, and gears are meticulously examined for correct tooth contact patterns and rolling torque, with backlash set precisely for proper lubrication and quiet operation. Axle tubes are inspected to meet OEM standards for straightness. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process. This comprehensive remanufacturing process sets a high standard for axle assembly quality. Key specifications include an 8.8-inch Ford-built ring gear, a 3.73 ratio, and compatibility with ABS. This axle assembly is of the semi-floating type, comes with a cover, but does not include differential fluid. It is built without Posi Traction.
