Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical accidents.

2. Drain Differential Fluid

Place a drain pan underneath the differential.
Remove the differential drain plug using a socket wrench.
Allow the fluid to fully drain into the pan.
Inspect the fluid for metal shavings or discoloration.

3. Inspect and Replace Components

Remove the rear differential cover using a socket set, being cautious with any residual fluid.
Inspect the gears, bearings, and seals for any wear or damage.
If any components are damaged, replace them as follows:
- Gears: Remove old gears and install new ones, ensuring proper alignment.
- Bearings: Use a bearing puller to remove old bearings and press new ones into place.
- Seals: Replace the differential cover gasket or seals with a new one to prevent leaks.

4. Reassemble Differential

Clean the differential housing and cover surfaces to ensure a proper seal.
Apply a suitable gasket maker or place a new gasket on the differential cover.
Reattach the cover and tighten the bolts to the manufacturer’s specified torque values.
Reinstall the differential drain plug and tighten securely.

5. Refill Differential Fluid

Using a funnel, refill the rear differential with the manufacturer-recommended fluid until it reaches the fill level.
Check the owner’s manual for the correct type of fluid and the fill capacity.

6. Final Checks

Reconnect the battery.
Start the vehicle and let it run for a few minutes, checking for any leaks around the differential.
Test drive the vehicle to ensure the noise has been resolved.
