AAM 11.5" AXLE ASSY 2012 CHY RAM 25

This is a remanufactured AAM 11.5" Axle Assembly from Zumbrota Drivetrain, designed for 2012 Ram 2500 and 3500 Single Rear Wheel (SRW) 4WD vehicles with a 3.42 gear ratio and a posi-traction differential. Zumbrota Drivetrain Axle Assemblies are rebuilt to exacting quality standards. Each assembly undergoes a thorough inspection for straightness, cracks, and surface wear. All internal components, including ring & pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. Crucially, all bearings and seals are replaced with new components. The gears are carefully inspected for optimal tooth contact patterns and are set with correct rolling torque using inch-pound measurements to ensure precise setup and longevity. Proper gear backlash is established for adequate lubrication and quiet operation. Additionally, axle tubes are inspected to meet OEM specifications for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting process for internal and external parts, followed by a proprietary shot-enticed deep cleaning, setting a high standard for remanufactured axle assemblies.
