This assembly is built to high standards of precision and reliability. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. Internal components, including ring and pinions, gears, clutches, and carriers, are fully inspected and tested. All bearings and seals are replaced, and gears are inspected for optimal tooth contact patterns and correct rolling torque for precise setup and longevity. Gear backlash is set to ensure proper lubrication and quiet operation, while axle tubes are inspected for OEM straightness. Zumbrota utilizes a hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process for its axle assemblies.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870871843128,"sku":"RAA435-2119A","price":1564.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-42-ratio-posi-limited-slip-differential-1","provider":"MOTORMIA","version":"1.0","type":"link"}
