Each unit undergoes thorough inspection for straightness, cracks, and surface wear. Internal components, including ring and pinions, internal gears, clutches, and carriers, are inspected and tested. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced. Gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precise setup and longevity. The gear backlash is set to ensure proper lubrication and quiet operation.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This rigorous cleaning process sets a high standard for axle assembly remanufacturing and brings the housings back to their OEM finish. The axle tubes are inspected and straightened to OEM specifications, and all housings are tested for surface wear and cracks.\n\nThis specific assembly is for differentials without Posi Traction and features a 12-bolt hexagon cover. It is important to note that this RAA435-138A assembly does not include hubs, brakes, backing plates, or axle shafts.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870739525944,"sku":"RAA435-138A","price":3205.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/chrysler-9-25-inch-3-55-gear-ratio-12-bolt-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
