    Have you popped the hood and started the truck. You could have a seized pully, that would cause your screeching sound. Where was the shaking originating from? Engine? Rear end? Front end? Does that truck have rear drum brakes? I wonder if something happened to one of the rear brakes and it is dragging causing you feeling of no power. We need more information, There are so many things it could be with the information that was given
