Answer
When you hear of people flushing the fluid. *DO NOT* do it with the engine running, or you'll have a powersteering rack full of air that may not be purged & operating for weeks.
You jack the front of the vehicle up & put it on jackstands. Unhook the resevior lines. One line goes to fresh fluid (say 2 quarts to be safe), the other goes to a bucket for old fluid. Turn the wheel from one lock to the other (it will be easy off the ground).

About 3-4 minutes of that & beautiful, fresh fluid will begin to pump out into the used container instead of nasty 10 year old fluid.



Changing just the pump is straight forward. Remove the belt & unhook the electro-hydraulics from it. Unbolt the pump & replace it. Plug the lines when you unhook them so they don't drain out all your fluid.
