Has anyone heard of the steering wheel moving on it on with the car running. I know this sounds crazy but I need help here. I changed the power steering return hose and had to drop my bracket I then removed my hoses to the valve but not the cylinder. after I replenished the fluid and started the car, I then moved the steering wheel and it went crazy moving hard right and left on it's own. I know my valve to steering cylinder hoses are not crossed because it happen both ways. Could it be the pump or cylinder out of rig. Please let me know. Thanks
