This includes thorough inspection for straightness, cracks, and surface wear. All internal components, such as ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. To ensure longevity and performance, all bearings and seals are replaced. The gears are precisely set for optimal tooth contact patterns, correct rolling torque (measured in inch-pounds), and proper backlash to ensure quiet operation and adequate gear lubrication.\n\nZumbrota Drivetrain ensures the integrity of the axle tubes meet OEM standards for straightness. Their remanufacturing process includes an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts, followed by a proprietary shot-enticed deep cleaning, setting a high standard for axle assembly remanufacturing.\n\nKey specifications include a 9.75-inch ring gear, a Ford-built component, and a 3.31 ratio with Posi Traction. The assembly also carries the Hollander number 44-1383A-P.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870909395256,"sku":"RAA440-1383A","price":1257.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/9-75-inch-posi-limited-slip-differential-rear-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
