steering box replacement

If you were to look at the top of the steering box, you'll see a screw surrounded by a large nut. The screw is about 3/8 of an inch in diameter, and will have either a slot (for a standard, straight-bladed screwdriver) or a hex (for an Allen-type driver) in it's top. The nut is a 3/4- or 11/16-inch nut that locks the screw. Holding the screw with the needed driver, loosen the large nut. This will free up the screw. Turn the screw in (tighten) about a 1/4 of a turn. Snug up the locknut, again while holding the screw to keep it from turning, start the car, and see how loose the steering is. The wheel shouldn't move more than about an inch before you see even the slightest movement at the front wheels. I you need to, repeat the process until you get the desired amount of play at the steering wheel.

A little adjustment goes a long way. Be VERY careful not to turn the screw in too far.
