This unit is designed for 1990-1991 GM 3500 Pickup trucks equipped with dual rear wheels (DRW) and features a 4.56 gear ratio with a G80 Posi Traction limited-slip differential.\n\nZumbrota Drivetrain rebuilds these axle assemblies to exacting standards, ensuring precision and reliability. The remanufacturing process includes a thorough inspection of all components for straightness, cracks, and wear. Critical internal parts like ring and pinions, internal gears, clutches, and carriers are fully inspected and tested. All new bearings, seals, crush sleeves, pinion nuts, and shims are replaced. Gears are meticulously set for optimal tooth contact patterns and correct rolling torque, using inch-pound measurements for setup accuracy and longevity. Backlash is precisely set for proper gear lubrication and quiet operation.\n\nThe housing and tubes are also inspected and straightened to OEM specifications. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, which prepares the internal and external parts to an OEM finish. Please note that this assembly does not include hubs, brakes, backing plates, or axle shafts.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870762430776,"sku":"RAA435-1659D-P","price":2699.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-axle-assembly-dana-70hd-4-56-ratio-g80-posi-drw","provider":"MOTORMIA","version":"1.0","type":"link"}
