This unit is built to stringent quality standards, ensuring precision and reliability. Each axle 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.\n\nKey components such as bearings and seals are replaced with new parts. The ring and pinion gears are inspected for optimal tooth contact patterns and correct rolling torque, with measurements taken in inch-pounds for precise setup and longevity. Gear backlash is set to ensure proper lubrication and quiet operation, while axle tubes are checked to meet OEM standards for straightness.\n\nZumbrota Drivetrain employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-peened deep cleaning process. This method sets a high standard for remanufactured axle assemblies. The unit is shipped in high-density plastic totes to minimize in-transit damage. This axle assembly is designed for the 2015-2017 Ford Expedition and Lincoln Navigator models and features a 3.73 gear ratio with Posi Traction and a 9.75-inch ring gear.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870911197496,"sku":"RAA440-1534C-P","price":2499.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-irs-rear-axle-assembly-3-73-posi-traction","provider":"MOTORMIA","version":"1.0","type":"link"}
