Out of curiosity, I went out and retrieved a ball I just removed from the pitman arm when I rebuilt mine. This one measures .964 on one side and .957 on the side 90 degrees from that. I think it is key to know this ball is supposed to be 1 inch in diameter when new. The takeaway here is this one was shot and allowed a notable amount of play and with new balls (same cups and springs...they were okay), it is now quite a bit tighter.
