Show original supplier description
The Zumbrota Drivetrain RAA435-2164A is a remanufactured rear differential assembly, precision-built for Ford 8.8" axles. This unit features a 2.73 gear ratio and is equipped to work with ABS systems, providing a standard replacement grade for enhanced reliability. Each axle assembly undergoes a rigorous inspection process, ensuring straightness, and checking for cracks and surface wear. Internal components, including ring and pinions, gears, clutches, and carriers, are thoroughly inspected and tested. Zumbrota replaces all bearings and seals, and meticulously sets gears for optimal tooth contact patterns, correct rolling torque measured in inch-pounds, and precise backlash to ensure proper lubrication and quiet operation. The axle tubes are inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This comprehensive remanufacturing process sets a high standard for axle assembly quality and longevity. The assembly includes a cover and has a fluid capacity of 3 quarts, though fluid is not included. It features 31 spline axles and is designed without Posi-Traction. Note that if the original vehicle had 28 spline axles, an upgrade to 31 spline axles will be necessary.
