This was the most convenient place I could think of to post this question; does anyone know how to get the outer CV joint apart, or can it be done at all?

I'm trying to rebuild my stock half shafts and the outer CV joint had some water get into it and bugger it up. I don't see the "snap ring" that the inner joint has that would allow the cage and balls to slide out of the cup (outer race) like the inner joint.
