I set my steering arms on the spindles at the right angle to get the proper Ackerman for my wheelbase. With a center pivot piece mounted as close to the axle centerline as possible. It is usually 90 square to the axle beam. Then on the steering shaft, with the wheels pointed straight, I rotate the pitman arm 30-45 degrees forward. Also build some steering stops into your spindles to keep it all from camming over past center. Once all that is set, I weld my steering quick disconnect hub on last with the wheel set where I want it
