Ford 8.8" 3.08 Posi Limited Slip Axle Assembly with ABS

The Zumbrota Drivetrain RAA435-1556B-P is a remanufactured axle assembly precision-built for 1991-1994 Ford Explorer, Mazda Navajo, and Mercury Mountaineer models. This unit is engineered with a robust Ford 8.8-inch ring gear and a 3.08 gear ratio, incorporating a Posi Limited Slip Differential for enhanced traction and is equipped to work with ABS systems. Every Zumbrota Drivetrain axle assembly is remanufactured to exacting quality standards, ensuring both precision and reliability. The process involves a comprehensive inspection of each unit for structural integrity, checking for straightness, cracks, and surface wear. All internal components, from the ring and pinions to the clutches and carriers, are meticulously inspected and tested. To guarantee longevity and optimal performance, all bearings and seals are replaced, and gears are carefully examined for ideal tooth contact patterns and set with precise rolling torque measurements. Furthermore, correct gear backlash is established to ensure proper gear lubrication and quiet operation, while axle tubes are verified to meet OEM straightness standards. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure for internal and external parts, followed by a proprietary shot-peening deep cleaning process. This rigorous cleaning and preparation method sets a high standard for axle assembly remanufacturing, ensuring a like-new component. This axle assembly includes the differential cover but does not include fluid. It is a semi-floating axle type and is Ford-built.
