I just did this for the first time last week. I just undid the 4 screws on the diffs (starting w/the front) I just turned it upside down and poured in the oil then I turned the car upside down so that I could mount the diff back on without the oil spilling. Screwed back in the screws then moved on to the center and basically did it the same way placing the drive shaft back in and moving on to the rear. It wasn't very difficult, though it was tricky with the front but became easier as I went along. Maybe there is an easier way but that's how I did it and it wasn't too bad.

QUESTION: when you change the oil do you just turn it over and drain out the old oil or do you guys take it apart and clean the parts and re-oil them?????
