Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle using a hydraulic lift or jack stands.

2. Drain Differential Fluid

Tools Required: Drain pan, socket set
Place the drain pan under the differential.
Remove the drain plug and allow the fluid to completely drain out.
Inspect the fluid for metal shavings or debris, which indicate internal wear.

3. Inspect and Replace Components

Inspect Gears: Remove the differential cover using a socket set. Look for wear on gears, bearings, and shims.
Replace Worn Parts: If any gears or bearings show signs of wear or damage, replace them with OEM parts.
Reassemble: Clean the differential housing and cover. Apply a new gasket or RTV sealant and reinstall the cover.

4. Refill Differential Fluid

Tools Required: Funnel
Reinstall the drain plug securely.
Using a funnel, fill the differential with the manufacturer-recommended fluid until it reaches the fill level.

5. Test Drive

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