During the remanufacturing process, all internal components are meticulously inspected and tested, including ring and pinions, internal gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced. Gears are set to exact backlash specifications to ensure proper lubrication and quiet operation, with rolling torque confirmed using inch-pound measurements for extended longevity. Axle tubes are also inspected and straightened to meet OEM standards.\n\nZumbrota Drivetrain employs an exclusive cleaning process that includes hydro-blast rinsing and sandblasting, followed by a proprietary shot-peened deep cleaning. This process restores housings to an OEM finish and ensures a clean foundation for the remanufactured components. The Posi Limited Slip Differential (LSD) provides enhanced traction for 4WD applications.\n\nFitment for this axle assembly is specific: it is designed for 2003 Dodge Ram 2500 and 3500 SRW 4WD vehicles with a 3.73 ratio. Some sources indicate broader fitment for 2005.5-2018 Dodge Ram models with specific Cummins engines and transmissions, but verification for your exact vehicle is recommended.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870879150392,"sku":"RAA435-2159A","price":4900.49,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/aam-11-5-axle-assembly-3-73-posi-lsd","provider":"MOTORMIA","version":"1.0","type":"link"}
