Remanufactured Axle Assembly 3.55 Ratio 8.8-Inch

The Zumbrota Drivetrain RAA435-2037E-P is a remanufactured complete axle assembly designed for 1999 and 2000 Ford F150 trucks. This unit features an 8.8-inch ring gear, a 3.55 gear ratio, and is configured for rear drum brakes. It also includes a Posi-Traction limited-slip differential. Zumbrota Drivetrain rebuilds these axle assemblies to exacting standards, ensuring precision and reliability. Each assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are inspected and tested. To guarantee optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are meticulously inspected for proper tooth contact patterns and set to the correct rolling torque using inch-pound measurements, with backlash adjusted for lubrication and quiet operation. Before reassembly, axle tubes are inspected and straightened to OEM specifications. Zumbrota employs a proprietary cleaning process that includes hydro-blasting, rinsing, and sandblasting, followed by a deep cleaning treatment, to ensure the housing is returned to an OEM finish. This comprehensive remanufacturing process sets a high standard for axle assembly rebuilds. Note that this assembly is for the axle assembly only and does not include hubs, brakes, backing plates, or axle shafts.
