Solution

1. Preparation

Gather tools and parts.
Lift the vehicle securely on jack stands.
Drain the differential fluid into a clean container.

2. Fluid Inspection and Replacement

Inspect Fluid: Remove the differential fill plug and check the fluid level. If the fluid is dark, contaminated, or smells burnt, it needs replacement.
Replace Fluid:
- Use a pump to fill the differential with fresh, manufacturer-recommended gear oil (typically 75W-90).
- Fill until fluid begins to seep from the fill hole.
- Reinstall the fill plug and ensure it is tight.

3. Bearing Inspection and Replacement

Remove Differential Cover:
- Unbolt and remove the differential cover.
- Clean the mating surfaces thoroughly.
Inspect Bearings:
- Check the condition of the ring and pinion gears.
- Rotate the gears to feel for any rough spots or binding.
Replace Bearings:
- If damaged, remove the old bearings using a bearing puller.
- Install new bearings using a press if necessary.

4. Reassembly

Reinstall the differential cover using new gasket material or RTV sealant.
Torque the bolts to the manufacturer’s specifications (typically 30-40 ft-lbs).
Recheck the fill plug for tightness.

5. Final Checks

Lower the vehicle and perform a test drive to ensure the noise has been resolved.
Monitor for any leaks around the differential area.
