I don't understand either. Does the steering wheel turn around without moving the pitman arm? (The pitman arm is the arm from the steering box shaft that connects to the steering linkage).Visable under the left front fender. If that is the case you will need to rebuild or replace the steering gear. You will need more then just a few tools to do it under a shade tree. You need a puller to remove the pitman arm. You should use a puller to remove the steering gear but it can be done without. The truck has to be up pretty high to get the gear out the bottom.
