Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Ensure the vehicle is on a level surface and securely lifted with jack stands.
  • Disconnect the negative battery terminal for safety.
2. Drain Differential Fluid
  • Place a drain pan under the differential.
  • Remove the differential drain plug using a socket set.
  • Allow the fluid to completely drain into the pan.
  • Inspect the fluid for metal shavings or debris, indicating wear.
3. Inspect and Replace Differential Components
  • Remove the differential cover by loosening the bolts with a socket set.
  • Inspect the ring and pinion gears for wear or damage.
  • If damaged, replace the gears with OEM parts, ensuring proper alignment during installation.
  • Replace any damaged bearings or seals.
4. Clean and Reassemble
  • Clean the differential housing and cover with a solvent to remove old gasket material.
  • Install a new gasket or sealant as per manufacturer specifications.
  • Reattach the differential cover and torque the bolts to the specified torque setting (typically around 30-40 ft-lbs, but check specifications).
5. Refill Differential Fluid
  • Replace the drain plug and torque it to the specified setting.
  • Refill the differential with the correct type and quantity of fluid (usually 75W-90 gear oil; consult the owner’s manual for specifics).
  • Replace the fill plug and ensure it is securely tightened.
