Hello, I'm Danny.
Here is the information you requested. It sounds like you are trying to remove the pitman arm from the steering link. The pitman arm to be removed requires a special tool due to the shear torque required of its installation. I've attached picture steps below for pitman arm removal and replacement on your Ford F-150. Hope this helps and thanks for using 2CarPros.
