10.5" Axle Assembly [4.30 Ratio, SRW]

The Zumbrota Drivetrain RAA435-1976C is a remanufactured complete axle assembly designed for the Ford 10.5" axle. This unit is specifically configured for 1999 Ford F-250 and F-350 models with a 4.30 gear ratio and Single Rear Wheel (SRW) setup. A Posi Limited Slip Differential (LSD) is included, but it is important to 'Check Tag' for specific compatibility. Each Zumbrota Drivetrain axle assembly undergoes rigorous rebuilding processes. This includes thorough inspection of the housing for straightness, cracks, and surface wear. All internal components, such as ring and pinions, gears, clutches, and carriers, are fully inspected and tested. To ensure longevity and reliability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are meticulously inspected for optimal tooth contact patterns, and correct rolling torque is established using inch-pound measurements for precise setup. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process for both internal and external parts. This cleaning method returns cases to their OEM finish, setting a high standard for remanufactured axle assemblies. The gear backlash is precisely set to guarantee proper gear lubrication and quiet operation, while axle tubes are inspected to ensure they meet OEM specifications for straightness. This remanufactured axle assembly comes with a 2-year limited warranty. Please note the 'Check Tag' instruction for compatibility, as variations may exist even within the specified vehicle models and years.
