Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted with jack stands.
Disconnect the battery to avoid any electrical issues.

2. Fluid Inspection and Replacement

Tools Required: Fluid pump, socket set, torque wrench.
Sub-steps:
1. Remove the differential fill plug using a socket wrench.
2. Check the fluid level; it should be at the bottom of the fill hole.
3. If low, drain the differential fluid using a fluid pump by removing the drain plug.
4. Inspect the drained fluid for metal shavings or discoloration (indicating wear).
5. Replace with manufacturer-recommended differential fluid, ensuring it is filled to the correct level.
6. Reinstall the drain and fill plugs, tightening them to the manufacturer’s specified torque.

3. Differential Inspection

Tools Required: Socket set, inspection mirror, flashlight.
Sub-steps:
1. Remove the differential cover (if applicable) to inspect internal components.
2. Check the gears for signs of wear or damage, such as pitting or chips.
3. Inspect the bearings for roughness or play.
4. Replace any damaged gears or bearings as necessary.

4. Reassembly and Testing

Tools Required: Torque wrench, socket set.
Sub-steps:
1. Reassemble the differential cover (if removed) and torque to specifications.
2. Reconnect the battery.
3. Lower the vehicle and perform a test drive to confirm the noise has been resolved.
