Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Drain Differential Fluid

Tools Required: Wrench set, drain pan
Locate the differential drain plug and remove it using the appropriate wrench.
Allow the fluid to completely drain into the drain pan.

3. Inspect and Replace Differential Components

Tools Required: Socket set, torque wrench, gasket scraper
Remove the differential cover by unscrewing the bolts; clean the mating surfaces.
Inspect the gears and bearings for wear or damage.
If necessary, replace any damaged components (e.g., bearings, gears).
Install a new gasket or use RTV sealant if applicable.

4. Refill Differential Fluid

Tools Required: Fluid pump
Reinstall the differential cover and torque the bolts to the manufacturer's specifications (usually around 30-40 Nm).
Refill the differential with new fluid using a fluid pump, ensuring to use the correct type as specified in the owner’s manual (typically 75W-90 synthetic gear oil).

5. Final Checks

Reconnect the battery.
Start the vehicle and let it run for a few minutes.
Recheck for leaks around the differential area after the vehicle has been driven short distances.
