The Zumbrota Drivetrain RAA435-2181A is a remanufactured axle assembly specifically designed for the Ford 8.8-inch differential, featuring a 3.55 gear ratio and configured for rear drum brakes. This assembly is built to stringent quality standards, ensuring precision and reliability. The remanufacturing process for this axle assembly is extensive. It begins with a thorough inspection of all tubes, ensuring they are straightened to meet OEM specifications. Housings are rigorously tested for surface wear and cracks. Internally, every component, including the ring and pinion gears, internal gears, clutch assemblies, and carriers, undergoes a 100% inspection. Furthermore, all bearings, seals, crush sleeves, and pinion nuts are replaced with new parts. The assembly process concludes with establishing the correct rolling torque using precise inch-pound measurements, critical for setup and long-term durability. To ensure a clean and OEM-like finish, all housings are cleaned using an advanced hydro blasting and rinsing process. The tag numbers associated with this unit are V746E and V746F. A refundable core charge of $400 applies to this product, which is returned upon receipt of your old, salvageable part.
