Solution

1. Preparation

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

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the differential drain plug using a socket set.
Allow the fluid to completely drain out and inspect for metal shavings or debris.

3. Inspect and Replace Differential Components

Inspect Bearings and Gears:
- Remove the differential cover by unscrewing the bolts.
- Inspect the gears and bearings for wear or pitting.
- If worn, remove and replace with new components.
Replace Seals:
- Remove old seals using a seal puller.
- Clean the area and install new seals.

4. Refill Differential Fluid

Use a fluid pump to fill the differential with the recommended type of gear oil (commonly 75W-90 for this vehicle).
Replace the drain plug and torque it to the manufacturer’s specifications (typically around 35-40 lb-ft).

5. Reassemble and Test

Reinstall the differential cover and torque the bolts according to specifications (usually around 20-25 lb-ft).
Reconnect the battery.
Conduct a test drive to confirm that the noise has been resolved and ensure proper function.
