Remanufactured Axle Assembly, 4.10 Ratio, Posi Limited Slip

The Zumbrota Drivetrain RAA435-2211B-P is a remanufactured axle assembly designed for Ford 8.8" differentials, specifically for 2003-2005 Ford Explorer models. This assembly features a 4.10 gear ratio and a Posi Limited Slip Differential (LSD) for enhanced traction. It is a Semi Floating axle type and comes with a cover, though fluid is not included. Each Zumbrota axle assembly is rebuilt to high standards, with thorough inspection of all components. This includes checking for straightness, cracks, and surface wear on housings and tubes, ensuring they meet OEM specifications. Internal components such as ring and pinions, internal gears, clutches, and carriers are 100% inspected. Crucially, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The assembly process includes setting correct gear backlash for proper lubrication and quiet operation, and establishing correct rolling torque using inch-pound measurements for precise setup and longevity. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning, to prepare internal and external parts, restoring housings to an OEM finish. This remanufacturing process aims for precision and reliability. Note: The Zumbrota RAA435-2211B-P is specifically designed for the 2003-2005 Ford Explorer. Fitment exclusions may apply to other Ford models, such as the 4 Door Sport Trac. Please verify compatibility before purchase.
