Unscrewing the oil drain plug from the rear final drive
1. Drive long enough to warm up the rear final drive to normal operating temperature.
2. Install the car in a horizontal position above the inspection hole.
3. Wipe the area around the fill/oil level plug on the rear final drive located on the left side and unscrew the plug.
4. Place a suitable container under the drain plug located on the right side of the rear final drive housing and unscrew the plug (see picture).
5. Drain the oil into a container. Clean the corks and remove metal particles from the magnets attached to the corks.
6. After draining the oil, clean the drain plug threads and reinstall the drain plug, tightening it to the correct torque.
7. Pour the exact amount of oil required into the final reverse gear and check the oil level. If exactly the required amount of oil is filled, and the oil level is above normal, install the oil level plug and make a short trip so that the oil is distributed among all elements of the rear final drive. Recheck the oil level and top up if necessary.
