This assembly features a robust Chrysler 8.25-inch ring gear with a 3.21 gear ratio and a semi-floating axle type. The unit includes a differential cover, but note that fluid is not supplied.\n\nZumbrota Drivetrain emphasizes quality and reliability in their remanufacturing process. Each axle assembly undergoes a comprehensive inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are carefully inspected for tooth contact patterns, and precise setup is achieved by establishing correct rolling torque using inch-pound measurements. Gear backlash is also precisely set to guarantee proper lubrication and quiet operation. Furthermore, axle tubes are inspected to meet OEM specifications for straightness, and housings are cleaned using an advanced hydro-blast and sandblasting procedure to restore an OEM finish.\n\nThis remanufactured axle assembly is specifically designed for the 1989-1990 Dodge Dakota 2WD models with a 2.5L engine and disc\/drum brakes.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870753812792,"sku":"RAA435-1614B","price":1808.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/chrysler-8-25-inch-3-21-ratio-rear-differential-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
