Remanufactured Complete Axle Assembly 3.73 Ratio

The Zumbrota Drivetrain RAA435-1931H is a remanufactured complete axle assembly for the Ford 8.8" differential, specifically designed for the 1999-2005 Ford Ranger. This unit comes equipped with a 3.73 gear ratio and is configured for vehicles utilizing 10" drum brakes. Each Zumbrota Drivetrain axle assembly is rebuilt to exacting standards of precision and reliability. The remanufacturing process involves a thorough inspection of the entire assembly for straightness, cracks, and surface wear. All internal components, including the ring and pinion, internal gears, clutches, and carrier, undergo a comprehensive inspection and testing phase. Crucially, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts to ensure optimal performance and durability. Gears are meticulously inspected to guarantee optimal tooth contact patterns and the correct rolling torque, measured in inch-pounds for precise setup and extended service life. Proper gear backlash is carefully set to ensure adequate gear lubrication and quiet operation. Furthermore, the axle tubes are inspected to confirm they meet OEM standards for straightness. Zumbrota Drivetrain utilizes an exclusive hydro-blast rinse and sandblasting procedure on both internal and external components, followed by a proprietary shot-peening deep cleaning process. This multi-stage cleaning and preparation method sets a high standard for axle assembly remanufacturing, ensuring a like-new finish and condition for all parts. The assembly is built to order and comes with a 2-year limited warranty.
