easiest way and fluid level

[GsXtUrBo98]

I am going to change the fluid in my rear end in my eclipse and also the transfer case. What would be the easiest way to change the fluid.

First im going to get it in the air on level ground. What would be the best way to get the fluid into the rear end and how much should I use in both the rear and transfer case???

Im going to use mobil 1 synthedic fluid in both.......

Any input would help out in this situation, thanks
