I often done Myself and seen other strike the Shaft end of a Puller on the Nut where you tighten it had have that pop loose what is being pulled.

Well, now we have an issue with the terminology.
When the OP stated that "the upper ball joint is frozen but the lower came out without too much effort", my determination was that he could not separate the UCA from the ball joint. This process would utilize the method that I described above.
If this was not the situation and the OP was attempting to remove the ball joint from the spindle, none of my previous advice would have been applicable and hammering on the side of the joint wouldn't accomplish a damn thing because
it's not a tapered joint.
The only method to remove and install the lower ball joint is FORCE......and a lot of it. This is best done with a hydraulic press, however the style noted in your post can possibly be successful, but I wouldn't count on it.
