4.10 Ratio Rear Axle Assembly

The Zumbrota Drivetrain RAA440-1288D is a remanufactured Dana 35IFS axle assembly specifically for the 1991-1997 Ford Explorer. This unit comes with a 4.10 gear ratio and a 7.562-inch ring gear, making it a standard replacement for your vehicle's drivetrain. Each axle assembly is rebuilt to high standards of precision and reliability. Zumbrota Drivetrain performs comprehensive inspections on all internal components, including ring and pinions, internal gears, clutches, and carriers, to ensure optimal performance. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced as part of the remanufacturing process. The gears are meticulously inspected for proper tooth contact patterns and correct rolling torque, using inch-pound measurements for precise setup and longevity. Backlash is set to ensure adequate gear lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-peening deep cleaning process. This rigorous cleaning ensures the housing is restored to an OEM finish. The axle tubes are also inspected for straightness to meet OEM standards. Units are shipped in high-density plastic totes to minimize in-transit damage. This axle assembly has a fluid capacity of 1.75 quarts and requires 80w-90 non-synthetic fluid, which is not included.
