Searched and found that this is trouble for many. Is there anything holding my pitman arm on the steering box shaft other than 1 nut and 1 lockwasher? I just broke a perfectly good pitman arm puller on the thing. It took a 1/2 inch breaker bar and a pipe extension. I tried pb blaster and some heat. I see no cross-pin (or reason for one) but it seems to be a huge amout of force. 1955 first series 1/2 ton. Thanks - Scott
