I use one large hammer to back up one side of the pitman arm then use another to hit the opposite side of the pitman arm. So basically I am just holding one hammer head on one side of the pitman arm and hitting the other side. I DO NOT hit the ball/bolt itself. I am hitting on the sides of the pitman arm which is like squeezing the metal arm and popping the bolt out of the hole. Sort of like popping a zit. You don’t hit the white head of a zit, you squeeze the sides to force it out. A little gross in this description I know, but I want you to understand the procedure. It takes a few good hits with the hammer, but it will eventually pop loose. Hitting or prying on the ball/bolt itself is useless. I take all tapered tie rod ends out this way and have never had one that I couldn’t break loose this way.
