The "best" way to adjust a HR steering box.

[Glenn 'Stinky' Stankevicius]

I know there are a couple of methods aside from the factory method, but what is the best way to adjust to get the best steering response without destroying the box?
One video (generic box) says to undo the locknut, tighten screw until it just stops, lock off and drive.
Another video says to undo the lock nut and tighten the screw in 1/4 turn increments, test drive, adjust again until optimal.
I haven't read the factory way yet as I don't have a HR manual, but I want to know the best method that is going to give me some confidence in my steering.

Be sure and take in to account the wear state of the worm shaft. They are invariably worn in the straight ahead position. If you adjust in this position it will bind when you turn. You must adjust off centre and put up with any slop in the straight ahead position I'm afraid.
My method is to raise front, turn 1/4 rotation one way, tighten to resistance, back off so wheel turns free and tighten lock nut. Then turn lock to lock to check free movement with no slop off centre. If there is no play in the straight ahead position after this you have a good box.
