Ok quick question about changing the gear oil since I am unfortunately stuck in the middle. I just drove the rear of my car on some rhino ramps to change the oil. That went well. Then I decided to change the gear oil. I unscrewed the filler screw and the oil started coming out. My understanding is that I should remove the filler screw stick my finger in and it should just be on the edge of the hole if it is full. Is the problem that I am on ramps and should have raised the car on all 4 corners to keep it even? How can I be sure if the gear oil is full if the car is leaning forward on ramps and it pours out? Will I have to get jack stands and raise the car on 4 of them? Thanks for any help!
