Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, OBD-II scanner, socket set, torque wrench, differential fluid.
Ensure the vehicle is on a level surface and securely raised with jack stands.
Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Locate the differential fill and drain plugs.
2. Remove the drain plug using a socket set and allow the old fluid to drain completely into a suitable container.
3. Inspect the old fluid for metal shavings or discoloration, indicating wear.
4. Replace the drain plug and torque to manufacturer specifications (consult the service manual for specific torque values).
5. Remove the fill plug and use a funnel to refill the differential with new fluid until it reaches the fill level.
6. Replace the fill plug and torque to manufacturer specifications.

3. Inspect Differential Components

Sub-steps:
1. Remove the differential cover if necessary, following the manufacturer's instructions.
2. Inspect gears and bearings for any signs of damage or unusual wear.
3. Replace any worn or damaged components, such as bearings or seals.
4. Clean the differential housing and cover before reassembly.
5. Apply new gasket material or sealant as required, and reattach the differential cover, torquing bolts to specifications.

4. Test Drive

Sub-steps:
1. Reconnect the battery.
2. Start the vehicle and check for leaks around the differential.
3. Conduct a short test drive to evaluate whether the noise persists.
