I have a 91 sport I converted to 4x4. Anyone know how to get the steering wheel back to center or "zero"? I have tried to mess with the steering box and even removing the steering wheel to reposition it. Thanks for any help.

 

the steering wheel is centered by the first adjustment off the draglink. just past the pitman arm. toe is adjusted on the other adjustment that ties the tires together.

 

+1 put the steering wheel back where it belongs so you don't wear out the box & pump.

You, sir, are working way too hard.

 

X2 on putting the steering wheel back where it was. Adjust the drag link (the rod with a sleeve that wraps around it from the pitman arm). Pull back and forth several times to make sure your vehicle is straight). Saturate it with PB Blaster, loosen the nuts, have a helper sit in the front seat while you turn the sleeve with a small pipe wrench and tell you which way the steering wheel is moving and when to stop. Tighten the nuts back up and take it for a ride, you might have to do it again after driving it if you want it centered perfectly.
