Dana 44 IFS Front Axle Assembly

The Zumbrota Drivetrain RAA440-1282D is a remanufactured complete axle assembly designed for the Dana 44 IFS front axle, specifically for 1983-1991 Ford F150 models with a 4.09 gear ratio and 8.5-inch ring gear. Each axle assembly is rebuilt to the highest quality standards for precision and reliability. The process involves a thorough inspection of the housing for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, undergo a comprehensive inspection and testing. To ensure longevity and performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are meticulously inspected for optimal tooth contact patterns and set to correct rolling torque using inch-pound measurements, with proper backlash established for adequate gear lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process for all internal and external parts. Units are shipped in high-density plastic totes to minimize the risk of in-transit damage. This remanufactured axle assembly comes with a 2-year limited warranty.
