How to adjust a manual steering box in a 1974 Jeep CJ5?

To adjust the manual steering box on a 1974 Jeep CJ5, first, ensure the vehicle is on a level surface and the steering is centered. Locate the adjustment screw on the top of the steering box, remove the cover if necessary, and use a wrench to slightly loosen the lock nut. Turn the adjustment screw clockwise to increase tension or counterclockwise to decrease it, checking for play in the steering wheel as you adjust.
