Ford 8.8" 4.10 Posi Traction Disc Rear Axle Assembly

The Zumbrota Drivetrain Reman Axle Assy is a fully remanufactured axle assembly specifically built for the 1997-1999 Ford F-150. This assembly features a robust Ford 8.8-inch ring gear with a 4.10 ratio, designed for optimal performance with Posi traction and rear disc brake systems. It is identified by tag numbers S871A and S871B. This remanufactured axle undergoes a rigorous inspection and rebuilding process to ensure reliability and longevity. Zumbrota Drivetrain inspects all tubes to ensure they are straightened to OEM specifications and tests all housings for surface wear and cracks. A thorough 100% inspection of all internal parts, including the ring and pinion, gears, clutch, and carrier, is performed. During the remanufacturing, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housing is then cleaned using a state-of-the-art hydro blasting and rinsing process, restoring it to an OEM finish. Precision setup and longevity are further ensured by establishing the correct rolling torque using inch-pound measurements. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts. Buyers should confirm fitment with their specific vehicle's tag numbers.
