3.31 Ratio Remanufactured Axle Assembly

The Zumbrota RAA440-1350E is a remanufactured axle assembly built to stringent quality standards for precision and reliability. Designed specifically for the Ford 8.8-inch IFS (Independent Front Suspension) system, this assembly is suitable for 1997-2002 Ford Expedition models with a 3.31 gear ratio and without a vacuum disc. Each unit undergoes a comprehensive inspection process, checking for housing straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, and carriers, are thoroughly inspected and tested. To ensure longevity and optimal performance, all bearings and seals are replaced, and gears are meticulously set for correct backlash, tooth contact patterns, and rolling torque measured in inch-pounds. The housing is cleaned using a state-of-the-art hydro-blast and rinsing process to restore it to OEM finish standards. This axle assembly has a fluid capacity of 2.2 quarts and requires non-synthetic 80w-90 gear oil. It is classified as a standard replacement grade type. Zumbrota Drivetrain utilizes high-density plastic totes for shipping to minimize the risk of in-transit damage. The remanufacturing process ensures that critical components are checked and replaced as needed, setting a high standard for quality and durability.
