8.8-inch Rear End 3.31 Ratio 31 Spline Semi-Float Axle Assembly

The Zumbrota Drivetrain RAA435-1692D is a remanufactured axle assembly specifically built for Ford 8.8-inch rear ends. This unit comes with a 3.31 gear ratio and 31 spline semi-float axles, designed for enhanced performance and durability. It's important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, requiring these components to be sourced separately. Each Zumbrota axle assembly is remanufactured with meticulous attention to detail. The process begins with a comprehensive inspection of all tubes to ensure they meet OEM specifications for straightness. Housings are rigorously tested for surface wear and cracks to guarantee structural integrity. Internals, including ring and pinion gears, clutch assemblies, and carriers, undergo a 100% inspection. During the remanufacturing process, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new components to ensure optimal performance and longevity. The housings are expertly cleaned using a state-of-the-art hydro blasting and rinsing process, restoring them to an OEM finish. Finally, the correct rolling torque is precisely established using inch-pound measurements, critical for setup accuracy and extended service life.
