Description

This remanufactured axle assembly undergoes rigorous rebuilding to ensure precision and reliability. The process includes thorough inspection for straightness, cracks, and surface wear, and full inspection and testing of all internal components (ring & pinions, gears, clutches, carriers). All bearings and seals are replaced with new parts. The assembly undergoes meticulous gear inspection for optimal tooth contact patterns and correct rolling torque, with precise setup using inch-pound measurements. Proper gear backlash is established for lubrication and quiet operation. Axle tube inspection ensures compliance with OEM straightness standards, followed by proprietary hydro-blast rinse, sandblasting, and shot-enticed deep cleaning of all parts.
