Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Fluid Inspection

Tools Required: Socket set, fluid pump, container
Check the differential fluid level using the fill plug.
If low, drain the old fluid into a container.
Inspect the fluid for metal shavings or burning smell; if found, further internal inspection is needed.

3. Replace Differential Fluid

Tools Required: Fluid pump, new differential fluid (OEM specified)
Refill the differential with the appropriate fluid until it reaches the fill plug level.
Replace the fill plug and torque it to the manufacturer's specification.

4. Inspect and Replace Bearings (if necessary)

Tools Required: Socket set, bearing puller, torque wrench
If noise persists, remove the differential cover and inspect the bearings.
Replace any damaged bearings with new OEM parts.
Reassemble the differential cover using a new gasket and torque bolts to specifications.

5. Final Assembly

Reconnect the negative battery terminal.
Ensure all tools are removed from the work area.
