When adjusting the drag on an older and worn steering box make certain to wind the wheel back and forth to test for binding while adjusting. The adjusting pin screws down into the worm gear slot (like a needle on a phonograph record). If the wheel is set in the normal straight ahead position and the pin is screwed down where most of the wear usually is, the pin may bind when the gear moves to turn to the left or right and the less worn section contacts the pin.
