Zumbrota Drivetrain Axle Assemblies are rebuilt to the highest quality standards of precision and reliability. Each Axle assembly is thoroughly inspected for straightness, cracks and surface wear. All internal components are fully inspected and tested including ring and pinions, internal gears, clutches and carriers. All bearings and seals are replaced. Gears are fully inspected for optimal tooth contact patterns and correct rolling torque using inch pound measurements for precise setup and longevity. Correct gear backlash is set to ensure proper gear lubrication and quiet operation. Axle tubes are inspected to ensure OEM standards of straightness. Zumbrota uses an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-enticed deep cleaning, setting the standard for Axle assembly remanufacturing.
