Only special tool I can think of is snap ring pliers to take the ring off inside the axle "tube". After you get everything off and have a little slack to work with you will need to remove the snap ring before you can slide the axle out.
As far as I know there is one CV that is made aftermarket and is a descent price, but the other side is only from Isuzu or a junkyard VX. Please someone clarify if I am right about that. If both CV's are made aftermarket please let me know where I can find them. I think I am running out of junkyard CV's and the Isuzu charges WAY too much for the new one.
