Solution

1. Preparation

Tools Required: Jack stands, wheel chocks, socket set, drain pan, funnel, torque wrench.
Raise the vehicle using a jack and secure it on jack stands. Ensure the vehicle is on a flat surface.
Wear safety glasses and gloves.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the drain plug using a socket wrench, allowing the fluid to completely drain out.
Inspect the old fluid for metal shavings or debris, which may indicate internal wear.

3. Inspect and Replace Differential Components

If noise persists after fluid change:
- Remove the differential cover by unscrewing the bolts.
- Inspect the gears, bearings, and shims for wear or damage.
- If damaged components are found, replace them as necessary (e.g., bearings, ring and pinion gears).
- Clean the differential housing and cover.

4. Reassemble and Refill

Reinstall the differential cover, applying a new gasket or sealant as necessary.
Torque the cover bolts to the manufacturer's specifications (typically around 30-40 ft-lbs).
Refill the differential with the recommended fluid type (likely 75W-90 gear oil) using a funnel until the fluid reaches the fill level.

5. Test and Monitor

Lower the vehicle and conduct a test drive to ensure the noise is resolved.
Monitor for any leaks or unusual sounds after the repair.
