Dana 60 Front Axle Assembly 3.73 Ratio

The Zumbrota Drivetrain RAA434-1352A is a remanufactured Dana 60 front axle assembly engineered for the 1999 Ford F350 Dual Rear Wheel (DRW) model with a 3.73 gear ratio. This axle assembly is rebuilt to stringent quality standards, ensuring precision and reliability. Each unit is meticulously inspected for straightness, cracks, and surface wear. Internal components, including ring and pinions, clutches, and carriers, are fully examined and tested. As part of the remanufacturing process, all bearings and seals are replaced. The gears are inspected for optimal tooth contact patterns and set for correct rolling torque using inch-pound measurements, ensuring precise setup and extended longevity. Gear backlash is carefully adjusted to promote proper lubrication and quiet operation. Axle tubes are also inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts. This is followed by a proprietary shot-enticed deep cleaning process, establishing a high standard for axle assembly remanufacturing. Key specifications include a 9.75-inch ring gear size, Dana 60 housing, 3.73 ratio, and a 1MM thick hub flange. This specific assembly is designed for the 1999 Ford F350 DRW, with some sources indicating fitment through March 14, 1999.
