Found this great instruction how to remove a pitman arm from a truck on ehow.com. A great resource! The pitman arm on a truck connects the steering box to the center link. The steering wheel on your truck connects to the steering box (sometimes referred to as the steering gear) by a long steel shaft. The pitman arm bolts to the bottom of the steering box and connects to the center link. The center link connects to spindle behind each front wheel. These parts are what causes your wheels to turn when you turn the steering wheel.
