One trick I did to my steering box was add a second bushing to the pitman shaft. When the housing was bored out, they cut the whole length to the same size. I simply installed the first bushing in the correct location, measured the length of the second bushing, cut it to size and installed it. This gives a lot more support out on the end of the pitman shaft. Before installing the second bushing, I used a dremel tool with ball cutter to cut an oil groove so the shaft wouldn't run dry. I didn't go all the way to the end, figured it would keep the 00 grease from seeping out. So far it's worked real good, I have zero side to side movement of the shaft.
