on whether you want to reuse the ball joint in question, of course.

I once upon a time picked up an air hammer kit at Sears or Home Depot or
such like, only about $20-30 or so, came with a chisel for cutting, one
or two weird tools, and a pickle fork thing that should be good for ball
joints.  Of course, you need compressed air to work it..."

A4 ball joints aren't a taper fit.  The tie rod ends are, but are easily 
removed with a substantial prybar and a BFH. You NEVER want to use a 
pickle fork as you'll destroy the boots, and a lot of the pieces are 
aluminum, something a pickle fork would not be gentle with. The prybar 
method requires loading the joint with the bar and smartly striking the 
part into which the tapered end fits. John
