2000 f250 with v10, got home from work today, then short time later we were going out again and my steering was extremely loose. Basically you could swing the wheel and it spins around. Power steering fluid was empty and I refilled it but still the same problem. Is there possibility that I'm just not using a thick enough power steering fluid? Need to know as soon as possible please. Thankyou.

 

Do the front wheels turn when you turn the steering wheel or not? Low power steering fluid should make it hard to turn the wheel.
