First thing to do is jack up the axle and support it on both sides with jack stands, with the tires a few inches off the ground. If the steering system is set up right, you should be able to spin the steering wheel lock to lock with just a couple of fingers. If not, start looking for tight spots one at a time- - - -king pins, drag link, tie rods, etc. You should also be able to grab either front tire and turn the wheels lock to lock with very little effort. Too-wide tires, or wheels with too much offset can also increase steering effort- - - -sometimes dramatically. An imaginary line drawn through the king pin, and another through the vertical centerline of the tires should intersect somewhere near the surface of the road. Wheels that increase the track width must scuff the tires across the road surface, instead of making a pivot point where the rubber meets the road.
