{"product_id":"dana-30-7-12-inch-3-21-ratio-rear-axle-assembly","title":"Dana 30 7.12-Inch 3.21 Ratio Rear Axle Assembly","description":"The Zumbrota Drivetrain RAA434-114A is a remanufactured complete rear axle assembly, specifically designed for the Dana 30 differential found in the 2007-2008 and 2011-2015 Jeep Wrangler models. This assembly includes the main housing and all internal components, such as ring and pinions, internal gears, clutches, and carriers. Crucially, it does *not* include axles, ball joints, spindles, steering components, or brakes, which must be sourced separately.\n\nZumbrota Drivetrain rebuilds these axle assemblies to rigorous standards, ensuring precision and reliability. Each unit undergoes thorough inspection for straightness, cracks, and surface wear. All internal components are meticulously checked, and all bearings and seals are replaced. The gears are inspected for optimal tooth contact patterns and precisely set rolling torque and backlash to ensure proper lubrication, quiet operation, and longevity. Axle tubes are checked for OEM straightness standards. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process, setting a high standard for remanufactured axle assemblies.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870717505848,"sku":"RAA434-114A","price":6205.09,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/dana-30-7-12-inch-3-21-ratio-rear-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
