🛠️ Pro Tips for Installation

  • Must Replace Fluid: Fresh, spec-approved differential gear oil MUST be used during the rebuild. Reusing old, contaminated oil will lead to premature bearing failure.
  • Professional Installation Recommended: Setting the correct pinion depth, backlash, and bearing preload is critical. Incorrect torque specs will destroy the new bearings instantly.
  • Housing Preparation: Thoroughly clean the internal differential housing of all metal shavings and sludge before installing the new KOYO/FAG bearings.
