The problem with trying to correct the steering wheel by removing it and putting it on straight is that the steering wheel is keyed too. It's only supposed to go on one way as the horn wiring runs up the side, not the center. If you don't care about the horn, go ahead and attach the wheel where you want. The drag link is where this problem starts and trying to correct it with out addressing it first is backwards.
Another way you can do this is have the jeep tires pointing straight, remove one end of the drag link, turn your key and move your steering wheel to center, remove the key locking the steering wheel straight, now turn the drag link so both ends extend the same amount and you are able to reattach the end you removed. You now have a straight steering wheel, the drag link centered end to end, and should have the same turning amount side to side.
P.S. I didn't bring it up because it looks like you already have a drop pitman arm, but if you have a lift and do not have a drop arm you will not, and cannot have the same turning radius to both sides. A lift with no drop pitman arm will give you a tighter turning radius to the left.
