I'm confused (but then again, that's easy to do). It looks like you have everything taken apart and the whole axle assembly should slide right out the back of the hub. The splined shaft that is on the far right of you picture is actually part of the half shaft and is attached to the outer CV joint (which as far as I know can't be disassembled). Might have to give the end of the splined shaft a gentle whack with a dead blow hammer to get it to start moving. Like Billy said, as long as the inner joint at the "green cup" is disassembled it should give you enough room to remove the whole half shaft.

Saying that, if no one has told you yet; once you get the inner CV joint boot off of the "green cup" (which is actually the outer race for the inner joint and is part of the axle shaft that fits into the front third member) there is a "snap ring" that is seated into a groove about 1/4" in from the edge of the green cup. If you use a screw driver to pry it out of the grove then the ball and cage assembly of the inner CV joint should pull right out.
