Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted using jack stands.
Disconnect the battery for safety.

2. Drain Differential Fluid

Use a socket set to remove the differential drain plug.
Allow the fluid to drain completely into a suitable container.
Inspect the old fluid for metal shavings or signs of contamination.

3. Remove Differential Cover

Remove the bolts securing the differential cover using a socket wrench.
Carefully pry the cover off without damaging the gasket surface.
Inspect the gears for wear or damage.

4. Inspect and Replace Components

Check the ring and pinion gears for wear patterns or pitting.
If damaged, replace the gears with OEM or equivalent parts.
Replace any worn bearings and seals during this process.

5. Reassemble and Refill

Clean the differential cover and replace the gasket or use a suitable sealant if needed.
Reattach the differential cover and torque the bolts to the manufacturer's specifications (check service manual for torque values).
Refill the differential with fresh oil, ensuring it meets the required specification (e.g., 75W-90 gear oil).

6. Final Checks

Reconnect the battery.
Lower the vehicle and perform a test drive to ensure the noise is resolved.
