Solution

1. Preparation

Tools Required: Floor jack, jack stands, oil drain pan, 8mm hex socket, torque wrench, funnel, and a clean rag.
Raise the vehicle using a floor jack and secure it with jack stands for safety.

2. Drain Old Differential Fluid

Position the oil drain pan beneath the differential.
Using an 8mm hex socket, remove the fill plug first to allow air in, preventing vacuum during drainage.
Remove the drain plug using the same hex socket and allow the old fluid to completely drain into the pan. Dispose of old fluid according to local regulations.

3. Clean and Inspect

Clean the drain plug and inspect the magnetic tip for metal shavings. This will indicate wear inside the differential.
Inspect the gasket on the drain plug for damage; replace if necessary.

4. Fill with New Differential Fluid

Using a funnel, fill the differential with the manufacturer-recommended fluid (check owner's manual for specifications).
Fill until the fluid starts to seep out of the fill hole, indicating it is full.
Reinstall the fill plug and tighten it to the manufacturer's specified torque (usually around 25 Nm).

5. Final Inspection

Start the vehicle and let it run for a few minutes to circulate the new fluid.
Check for leaks around the fill and drain plugs after the vehicle is turned off.
