Power Steering Adjustment.

My 84 F250 power steering is wandering all over the road. Suspect I will need to replace the Steering gear box, but would like to try to get the slack out of the Steering gear box first. Can I just adjust the preload without having to remove the Pitman Arm and draining the Steering gear box fluid as it states in the repair manual without sacrificing safety? Which way should I be turning the preload adjusting screw to take up the slack and in what increments?

Re: Power Steering Adjustment.

I don't know why you would have to drain the oil, etc.

With the wheels straight ahead, loosen the jam nut, then turn the stud clockwise until it just bottoms (do not tighten it any further). While holding the stud, retighten the jam nut.

Once you have done this, carefully test drive the truck to make sure there is no binding in turns. Since the gears tend to wear more in the straight ahead position, if there is a lot of wear there can be binding in turns when the gears mesh in a lesser worn area.
