Solution

1. Preparation

Tools Required: Socket set, jack stands, OBD-II scanner, fluid pump, torque wrench.
Safety Warnings: Ensure the vehicle is on a level surface and secured with jack stands before working underneath.

2. Differential Fluid Change

Drain Old Fluid:
- Locate the differential drain plug and remove it using the appropriate socket.
- Allow the fluid to completely drain into a suitable container.
Inspect Drain Plug:
- Check the drain plug for metal shavings or debris. Clean or replace if necessary.
Fill with New Fluid:
- Using a fluid pump, fill the differential with the manufacturer-recommended fluid until it reaches the fill level.
- Replace the fill plug and torque to the factory specification.

3. Inspect and Repair Differential Components

Remove Differential Cover:
- If leaks or damage are suspected, remove the differential cover by unbolting it.
- Inspect the gears and bearings for wear or damage.
Replace Worn Components:
- If any components show signs of wear, replace them with OEM parts.
- Reassemble the differential cover with a new gasket or sealant as required.

4. Reassemble and Test

Reinstall Components:
- Reinstall any parts removed during the inspection, ensuring all bolts are torqued to specifications.
Test Drive:
- Take the vehicle for a test drive under various driving conditions to ensure the noise has been resolved.
