Remanufactured Axle Assembly 4.10 Posi Traction Limited-Slip Differential

The Zumbrota Drivetrain RAA435-2210-P is a remanufactured complete axle assembly built to high standards of precision and reliability. This unit is designed for Ford 10.25-inch differentials, featuring a 4.10 gear ratio and a Posi Traction limited-slip differential for enhanced traction. It is specifically intended for 2004-2008 Ford F150 models equipped with 7-lug axles and disc brakes. During the remanufacturing process, every axle assembly is thoroughly inspected for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. To ensure optimal performance and longevity, Zumbrota replaces 100% of bearings, seals, crush sleeves, pinion nuts, and shims. The gears are carefully inspected for proper tooth contact patterns, and their rolling torque is precisely set using inch-pound measurements. Gear backlash is also set to ensure correct lubrication and quiet operation. Zumbrota employs a proprietary cleaning process that includes an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts. This is followed by a deep cleaning process that sets a high standard for remanufactured axle assemblies, returning housings to an OEM finish. All axle tubes are inspected to ensure they meet OEM specifications for straightness, and housings are tested for any surface wear or cracks. This comprehensive approach ensures a reliable and durable product. This assembly does not include hubs, brakes, or axle shafts, and requires a core charge for the remanufactured unit.
