Dana 30 3.55 Remanufactured Axle Assembly

The Zumbrota Drivetrain RAA440-1376A is a remanufactured axle assembly specifically designed for the Dana 30 differential with a 3.55 gear ratio, intended for 2002-2005 Ford Explorer models. Each axle assembly is meticulously rebuilt to high standards of precision and reliability. Zumbrota Drivetrain ensures the highest quality through a comprehensive process that includes thorough inspection of the housing for straightness, cracks, and surface wear. Internally, all components such as ring & pinions, internal gears, clutches, and carriers are fully inspected and tested. Furthermore, all bearings, seals, crush sleeves, pinion nuts, and shims are 100% replaced to guarantee optimal performance and durability. The remanufacturing process includes a specialized cleaning regimen, utilizing an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process. This extensive cleaning restores cases to an OEM finish. Critical setup procedures, such as establishing correct rolling torque using inch-pound measurements, are performed to ensure precision setup and longevity. Proper gear backlash is also set to guarantee adequate gear lubrication and quiet operation. This axle assembly is noted as 'Assembly only; axles not included', indicating that the axles themselves are not part of this specific remanufactured unit. Units are shipped in high-density plastic totes to minimize in-transit damage.
