This unit comes equipped with a Posi Limited Slip Differential, providing enhanced traction, and features a 3.55 gear ratio with an 8.8-inch ring gear.\n\nInternal components, including ring and pinions, gears, and carriers, undergo rigorous inspection and testing. All bearings and seals are replaced as part of the remanufacturing process. The gears are meticulously inspected for optimal tooth contact patterns, and correct rolling torque is set using inch-pound measurements to ensure precise setup and longevity. Proper gear backlash is established to guarantee adequate gear lubrication and quiet operation, while axle tubes are verified to meet OEM standards for straightness.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This comprehensive approach sets a high standard for axle assembly remanufacturing, emphasizing precision and reliability. This particular axle assembly is designed for Truck\/SUV applications and is noted to have a 3.55 ratio with Posi Traction, an 8.8-inch ring gear, and importantly, no ABS sensor in the housing. It is compatible with various Ford and Mercury models including Eddie Bauer, Explorer, Limited, Mountaineer, Premier, and XLT trims from the 2007-2010 model years.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870906216760,"sku":"RAA440-121A-P","price":1799.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/8-8-inch-rear-axle-assembly-w-3-55-posi-limited-slip-diff","provider":"MOTORMIA","version":"1.0","type":"link"}
