There is a huge amount of play in my steering, so I read this post with interest. Among the advice:
…have someone turn the steering wheel back and forth while you watch the rag joint and the input and output shafts on the steering box for slop.
There is an adjustment on the steering box. Look for a 5/8 or 11/16 nut usually on the side of the box. It is on a shaft that usually has as screwdriver slot in it. Raise your front end off the ground. Center the wheels. Hold the center shaft while you break loose the nut. Turn the screw in to some resistance. Temporarily tighten the lock nut. Check for play again. If the adjustment is too tight, steering will be stiff at center. If so, back off a little.
…in addition, the correct way is to disconnect the drag link as well. As long as I have dealt with the lash in any Saginaw box, the correct way was just the same as any adjustment. All adjustments are made off-vehicle, so you must, as the books say, remove all preload. Which means pulling the drag link. Make it seem like it is off vehicle. While true final adjustment is made with the steering wheel connected and the gearbox mounted, note that the drag link is not! Also note that a dial indicator and lb-in torque wrench are also used. Inch pound that is, which means there is little room for mistake/carelessness.
