Solution

1. Preparation

Tools Needed: Floor jack, jack stands, socket set, torque wrench, differential fluid, mechanic's stethoscope.
Raise the vehicle using a floor jack and securely place it on jack stands.
Ensure the vehicle is on a flat surface and the engine is off.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Locate the differential drain plug and remove it using a socket wrench.
2. Allow the old fluid to completely drain into a suitable container.
3. Inspect the old fluid for metal shavings or debris; if present, further internal inspection may be needed.
4. Clean the drain plug and replace the washer if necessary.
5. Reinstall the drain plug and tighten to the manufacturer’s specifications (typically around 30-40 ft-lbs).
6. Remove the fill plug and fill the differential with new fluid using a funnel until it reaches the fill level. Refer to the owner’s manual for the correct type and amount of differential fluid.

3. Inspect and Replace Differential Components (if necessary)

Sub-steps:
1. If noise persists, remove the differential assembly as per the service manual instructions.
2. Inspect the ring and pinion gears for wear, scoring, or pitting.
3. Check bearings for play or roughness; replace if any issues are found.
4. Replace any damaged components, ensuring to use OEM or high-quality aftermarket parts.
5. Reassemble the differential, ensuring proper torque specifications for all bolts.
6. Reinstall the differential assembly back into the vehicle.

4. Test Drive

Take the vehicle for a test drive to ensure the noise has been resolved and everything is functioning correctly.
