Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with jack stands.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Locate the differential fill plug and drain plug.
2. Using a socket wrench, remove the drain plug and allow the old fluid to completely drain into a pan.
3. Inspect the drained fluid for metal shavings or burnt smell, indicating internal damage.
4. Replace the drain plug and torque it to the manufacturer's specification (typically around 30 ft-lbs).
5. Remove the fill plug and refill the differential with new fluid (refer to the owner's manual for the correct type and quantity, usually a GL-5 rated gear oil).
6. Reinstall the fill plug and torque to specification.

3. Inspect and Replace Differential Components (if necessary)

Sub-steps:
1. If abnormal sounds persist, remove the differential from the vehicle, following the service manual for specific instructions.
2. Inspect internal gears, bearings, and seals for wear or damage.
3. Replace any damaged components, ensuring to use OEM or high-quality aftermarket parts.
4. Reassemble the differential, applying the specified torque settings to all bolts.
5. Reinstall the differential in the vehicle, ensuring all connections are secure.
