Remanufactured Rear Axle Assembly 3.31 Ratio

The Zumbrota Drivetrain RAA435-2036D-P is a remanufactured rear axle assembly meticulously rebuilt to exacting standards for 1999 and 2000 Ford F-150 trucks. This unit features a 3.31 gear ratio, a robust Ford 8.8-inch ring gear, and is configured for rear disc brake systems. It comes equipped with Posi Traction for enhanced performance, but buyers should note that hubs, brakes, backing plates, and axle shafts are not included and must be sourced separately. Zumbrota Drivetrain emphasizes quality in their remanufacturing process. Each axle assembly is subjected to a comprehensive inspection, including checks for straightness, cracks, and surface wear on housings. Internally, all components such as ring and pinions, gears, clutches, and carriers are thoroughly inspected and tested. To ensure longevity and reliable operation, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are precisely set to ensure optimal tooth contact patterns, correct backlash for lubrication and quiet operation, and proper rolling torque measured in inch-pounds. The remanufacturing process includes a proprietary hydro-blast rinse and sandblasting procedure for both internal and external parts, followed by a deep cleaning process that restores the housing to an OEM finish. All tubes are inspected and straightened to meet OEM specifications. This attention to detail ensures that each remanufactured axle assembly meets high standards of precision and reliability. This axle assembly is specifically designed for the 1999-2000 Ford F-150, including Base, Lariat, Lightning, XL, XLT, and Harley-Davidson Edition sub-models, across various engine options (4.2L, 4.6L, 5.4L). It is compatible with vehicles featuring rear disc brakes and the S826A tag number. It is crucial to verify that this specific axle assembly meets the requirements for your vehicle's configuration, as it does not include essential components like hubs, brakes, backing plates, or axle shafts.
