To check for wear in the center pin, have a friend turn the steering wheel back and forth while you place your hand on the top of the arm that is attached on the pin. If you feel the arm moving up and down before it spins then it needs to be replaced. We can rent you a tool that makes this job real easy on all buses to 1979.
