Chevrolet GMC Differential - Rear

Zumbrota Drivetrain Axle Assemblies are rebuilt to the highest quality standards. Each axle assembly is inspected for straightness, cracks, and surface wear. All internal components are fully inspected and tested, including ring & pinions, internal gears, clutches, and carriers. All bearings & seals are replaced. Gears are inspected for optimal tooth contact patterns and correct rolling torque. Correct gear backlash is set for proper 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.
