Remanufacturing Process

Every differential and axle assembly we sell is fully remanufactured to meet or exceed OEM specifications. Our remanufacturing process:

  • Deep Clean – To start the remanufacturing process, each unit is fully disassembled and cleaned.
  • Inspection – The ring and pinion, internal gears, clutches and carriers are carefully inspected. Gears are checked for proper tooth contact, and axle tubes are inspected for straightness.
  • New Components – All seals and bearings are replaced, and gears are reset for correct rolling torque for maximum efficiency and performance. Backlash is reset carefully for maximum longevity and quiet operation.
  • Validation – After reassembly, each unit is spin tested as part of a detailed checklist validation process.

Because of our rigorous remanufacturing process, we can offer the industry’s best warranty on remanufactured differentials and axle assemblies. Each one comes with up to 7 years and 1 million miles of warranty, which can be upgraded to include Pure Care™ no-fault protection. No other differential and axle assembly manufacturer comes close.
