Zumbrota Bearing & Gear Differential 434-121B

Zumbrota Reman Axle Assemblies undergo the industry's most comprehensive cleaning and inspection process. Cases and housings are thoroughly inspected for cracks and straightness, all internal components are inspected for wear and every bearing and seal is replaced. Gear pattern is checked for optimal tooth contact, proper pinion bearing preload is established and correct backlash is set to ensure years of quiet operation.
