Power Steering leak at input shaft

I drive a 2009 WRX (no mods) and noticed that I was leaking power steering fluid recently. A little troubleshooting and I discovered the source, the leak is originating from the input shaft coming into the rack and pinion gearbox.

The Subaru service manual that I found online states for this type of leak to 'Replace the valve assembly with a new part'. However when I inquired at the dealership they told me they don't sell that part, they only sell the entire rack and pinion for $750.

Looking at the gear box it is obvious that it is replaceable, but I cannot find a part number. I really do not want to replace my entire rack and pinion for what is most likely a worn bearing in the gearbox. Any advise would be greatly appreciated.
