Solution

1. Preparation

Gather tools: socket set, torque wrench, fluid pump, drain pan.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the drain plug using a socket set and allow the old fluid to fully drain.
Inspect the fluid for metal shavings or debris, indicating internal wear.

3. Inspect and Replace Differential Components

Remove the differential cover if damage is suspected.
- Sub-steps:
  - Remove bolts securing the cover with a socket set.
  - Carefully pry the cover off, ensuring not to damage the gasket surface.
Inspect the ring and pinion gears for wear or damage.
Replace any worn components, such as bearings or seals, as necessary.

4. Clean and Reassemble

Clean the differential cover and the mating surface thoroughly.
Apply a new gasket or RTV sealant as required.
Reinstall the cover and torque the bolts to the manufacturer's specifications (typically around 30-40 ft-lbs).

5. Refill Differential Fluid

Use a fluid pump to refill the differential with the recommended fluid type (usually 75W-90 gear oil).
Fill until fluid begins to seep from the fill hole, indicating the correct level.

6. Final Checks

Reconnect the battery.
Start the vehicle and listen for any abnormal noises.
Test drive the vehicle to ensure noise has been resolved.
