easiest way:
remove the pinch bolt, then pry on the control arm with a LONG prybar. if that dont do it hammer a pickle fork in the balljoint while prying (air chisel pickle fork is easiest)
cut an "X" in the head of the rivet, then air chisel it off. after all 3 are off, use the air chisel bit in between the balljoint and the control arm, it pops right out. i just did 2 balljoints in about 30 min with this method on a 98 zetec contour at work (im a mechanic and used a lift and all the right tools thats why i did it so fast)
