ball joint separator

[ricurt69]

On a 72 C10 I'm installing CPP lowered spindles. All the ball joints came apart with carful use of a pickle fork and a little hammer work ...except for the passenger side lower. Also tried a screw type separator that is useless on the lower joints wider surface. After lubing, a lot of hammering, air chisel etc it will not budge. I think the fork which is 5/8" thick bottoms on the joint and does not spread enough to pop the joint. I've already ripped the boot. Anyone make a ticker fork, or do the Lisle stepped forks work?
