I was driving the other day and I heard this ting ting ting bang stopped looked seen my serpentine belt was off and shredded. I got a new one put it on and started it up and it shot my power steering pulley out the pump. Do I need to replace the whole assembly or can I get just the pulley?

Nope. The shaft is broken. If you pull the pulley forward, you will see part of the shaft will come out with it. I do not know what causes this. We never had this problem many years ago, but today it is not uncommon.

Be aware that once the pump is replaced, it can be a very tedious process to bleed the air out on most Ford products. You will think everything is working okay, then when you stop the engine, a bunch of power steering fluid will leak onto the ground. (Overflow the reservoir). While running and the system is under pressure, air trapped in the system gets seriously compressed and does not want to work its way out. When you stop the engine and the pressure goes away, that air expands and pushes the fluid out. There are special funnels that capture that fluid and let it run back into the reservoir. Every mechanic has his tricks to getting the air out, so do not get excited if you run into this.

I am not understanding "pulley shaft". The pulley and the shaft are two separate parts. The pulley is pressed onto the shaft. I have never seen one come off on its own. Normally the shaft breaks inside the pump in such a way that half of it can be pulled out of the pump still attached to the pulley. When you do that, power steering fluid will run out too, so be ready with a pan or bucket.
