Info about the steering box?
I can't find any info about the steering housing on a JK.... 
Here's a pic of the steering housing on a YJ. I want to adjust the pitman shaft.
Is it the same way on a JK?
Any links or more info?

The JK steering gear has the same adjustment nut on top.
Here is the procedure from the 2008 service manual:
(The stub shaft is the input shaft the steering column attaches to.)
STEERING GEAR
NOTE: Adjusting the steering gear in the vehicle is not recommended. Remove gear from the vehicle and drain the fluid. Then mount gear in a vise to perform adjustments.
OVER-CENTER
1. Rotate the stub shaft with Socket 8343 from stop to stop and count the number of turns.
2. Center the stub shaft by rotating it from the stop 1/2 of the total amount of turns.
3. Place torque wrench and Socket 8343 in a vertical position on the stub shaft. Rotate the wrench 45 degrees each side of the center and record the highest rotational torque in this range. This is the Over-Center Rotating Torque. NOTE: The stub shaft must rotate smoothly without sticking or binding.
4. Rotate the stub shaft between 90° and 180° to the left of center and record the left off-center preload. Repeat this to the right of center and record the right off-center preload. The average of these two recorded readings is the Preload Rotating Torque.
5. The Over-Center Rotating Torque should be 0.45-0.80 N·m (4-7 in. lbs.) higher than the Preload Rotating Torque.
6. If an adjustment to the Over-Center Rotating Torque is necessary, first loosen the adjuster lock nut. Then turn the pitman shaft adjuster screw back (COUNTERCLOCKWISE) until fully extended, then turn back in (CLOCKWISE) one full turn.
7. Remeasure Over-Center Rotating Torque. If necessary turn the adjuster screw and repeat measurement until correct Over-Center Rotating Torque is reached. NOTE: To increase the Over-Center Rotating Torque turn the screw CLOCKWISE.
8. Prevent the adjuster screw from turning while tightening adjuster lock nut. Tighten the adjuster lock nut to 37-52 N·m (27-38 ft. lbs.).
Here is the procedure from the 2008 service manual:
