Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Allow the vehicle to cool if it has been recently driven.

2. Check Differential Fluid

Tools Required: Socket set, drain pan
Remove the differential fill plug using a socket.
Check the fluid level; it should be at the bottom of the fill hole.
Inspect the fluid for metal shavings or discoloration.

3. Replace Differential Fluid (if necessary)

Tools Required: Socket set, fluid pump, new differential fluid
Place a drain pan under the differential and remove the drain plug.
Allow the old fluid to completely drain.
Reinstall the drain plug and torque to manufacturer specifications.
Use a fluid pump to fill the differential with new fluid until it reaches the fill hole.

4. Inspect Differential Components

Tools Required: Inspection mirror, flashlight
Visually inspect the differential housing, gears, and bearings for any signs of wear or damage.
Check the CV joints and U-joints for excessive play or damage.

5. Test Drive the Vehicle

Perform a test drive to determine if the noise persists after fluid replacement and inspections.
Monitor for any changes in noise during acceleration, deceleration, and turning.
