Each assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. Crucially, all bearings and seals are replaced.\n\nGears are examined for optimal tooth contact patterns and precise rolling torque measurements for longevity. Backlash is set correctly to ensure proper gear lubrication and quiet operation, while axle tubes are verified to meet OEM standards for straightness. Zumbrota employs a unique hydro-blast rinse and sandblasting procedure on all parts, followed by a proprietary shot-peened deep cleaning process, establishing a high standard for remanufactured axle assemblies.\n\nThis axle assembly is engineered with a 4.30:1 gear ratio and a Posi-traction (limited-slip) differential, utilizing a 10.5-inch axle diameter. It is a direct-fit component for specific vehicle applications.\n\nFitment is confirmed for the following:\n- 1999-2000 Ford Excursion\n- 1999-2000 Ford F-350 SUPER DUTY\n- 2005.5-2018 Dodge Ram models equipped with a 5.9L or 6.7L Cummins engine and a 6-speed transmission (specifically those with 400HP and 900 Ft-lbs. ratings).","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870810992952,"sku":"RAA435-1978C-P","price":2136.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-axle-assembly-4-30-1-posi-traction","provider":"MOTORMIA","version":"1.0","type":"link"}
