I've changed CV boots on my 928, but I can see from photos that those on your 996 look almost identical.
It's important that the inner hub is oriented correctly with respect to the outer collar. It will go in either way, but if you do it the wrong way the joint will not be able to move more than slightly!
It sounds as if you've done this. The photo shows the correct orientation, with the wide sections of the inner hub opposite the narrower sections of the outer collar. I wonder if you've reassembled the CV joint with the narrow sections opposite each other?
