Yo ski,
Ensure the gear box is the Ford unit and not an aftermarket piece.
See parts diagram and illustration in link below.

(Part of 3568)
9 3D517 Power Steering Gear Input Shaft and Control
Pre-load Adjustment, All Bronco & Ford, mid-70s to 00; "...
With the engine (6007) off, turn the steering wheel (3600) from full right stop to full left stop at least once.
Disconnect the pitman arm from the sector shaft using a Pitman Arm Puller (Tool T64P-3590-F).
2. Disconnect the fluid return line at the reservoir and cap the reservoir return line ****** to retain the fluid in the reservoir.
3. Place the end of the return line in a suitable container and turn the steering wheel from stop-to-stop several times to discharge the fluid from the gear. Discard the fluid.
4. Turn the steering wheel to the right stop, then back left 45 degrees.
5. Attach an inch-pound torque wrench to the steering wheel nut and determine the torque required to rotate the shaft slowly approximately one-eighth turn (45°) toward center from the initial 45 degree position. Note this first value.
6. Turn the steering gear back to center and determine the torque required to rotate the shaft back and forth across the center position (± 90°). Compare the center value to the first value, using the following criteria:
* Vehicles with less than 5,000 miles (8046 Km):
If total meshload over mechanical center is less than 15 in-lb (1.7 Nm) or greater than 24 in-lb (2.7 Nm), RESET to first value PLUS 11-15 in-lb (1.2-1.7 Nm).
* Vehicles with more than 5,000 miles (8046 Km), or with new sector shaft:
If meshload over mechanical center is NOT 7 in-lb (0.8 Nm) GREATER than the first value, RESET to 10-14 in-lb (1.13-1.6 Nm) GREATER than first value.
7. If reset is required, loosen the adjuster locknut and turn the sector shaft adjuster ***** until the reading is the specified value greater than the torque at 45 degrees from the stop. Hold the sector shaft ***** in place, and tighten the locknut.
8. Re-check torque readings and replace the pitman arm and steering wheel hub cover.
9. Connect the fluid return line to the reservoir and fill the reservoir to specification with the specified fluid. Check belt tension & adjust if necessary.
Do not pry against the reservoir to obtain proper belt load. Pressure will deform the reservoir and cause it to leak." See Diagram included

As you see above.., this is not to be taken lightly.
This *****/lock-down nut is for setting the pre-load on a new, or low milage box.
Moving this ***** on a high mile (sloppy steering) box is not recommended.
Re-building the box IS recommended.
