The \"*Check Tag*\" notation in its designation suggests verifying the vehicle's original axle tag for precise compatibility.\n\nZumbrota Drivetrain emphasizes precision and reliability in their remanufacturing process. Each axle assembly undergoes rigorous inspection for straightness, structural integrity (cracks), and surface wear. All internal components, including the ring and pinion gears, differential gears, clutches, and carrier, are meticulously inspected and tested. To ensure longevity and optimal performance, all bearings and seals are replaced with new ones. The gears are set for precise tooth contact patterns and rolling torque, with backlash adjusted correctly for proper lubrication and quiet operation. Axle tubes are checked against OEM standards for straightness.\n\nThe remanufacturing process includes an exclusive hydro-blast rinse and sandblasting procedure for internal and external parts, followed by a proprietary shot-peened deep cleaning. This comprehensive cleaning and inspection process aims to set a high standard for remanufactured axle assemblies. The assembly includes a differential cover but does not come pre-filled with fluid, and mounting hardware is not included.\n\nKey specifications include a 9.75-inch ring gear diameter, a 3.55 gear ratio, 14 MM wheel studs, and 2.533 OD wheel bearings. The axle type is semi-floating, and the differential is a Posi Limited Slip type. The fluid capacity is 3.5 quarts, but fluid is not included.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870822330680,"sku":"RAA435-2021D","price":2176.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/p-rear-axle-assembly-posi-limited-slip-3-55-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
