Each unit undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are inspected and tested. Crucially, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. Gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, set using precise inch-pound measurements for longevity and proper function. The gear backlash is set to ensure optimal lubrication and quiet operation. Axle tubes are inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, setting a benchmark for remanufactured axle assemblies. The housing is cleaned using a state-of-the-art hydro blasting and rinsing process, restoring it to an OEM finish. This axle assembly does not include hubs, brakes, backing plates, or axle shafts. It is built to order and has a 2-year limited warranty.
