Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, basic hand tools (sockets, wrenches), differential fluid, drain pan.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the vehicle to cool down before starting work.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the differential drain plug using the appropriate socket.
Allow the fluid to fully drain; inspect for metal shavings or debris in the fluid.

3. Inspect and Replace Differential Components

Inspect Gears and Bearings:
- Remove the differential cover by unscrewing the bolts.
- Inspect the ring and pinion gears for wear, pitting, or chips.
- Check the differential bearings for smooth operation; replace if rough or noisy.
Replace Worn Components:
- If any gears or bearings show signs of damage, replace them with OEM parts.
- Reassemble the differential housing after ensuring all components are in good condition.

4. Refill Differential Fluid

Clean the differential cover and replace the gasket if necessary.
Reattach the cover and torque the bolts to the manufacturer’s specifications.
Refill the differential with the recommended fluid using the fill plug.

5. Final Checks

Reinstall the drain plug and ensure it is tightened.
Lower the vehicle and take a test drive to confirm the noise has been resolved.
