power steering flush

[968]

i read somewhere that flushing your power steering fluid is a relatively simple task. i haven't been able to find a write up on it. once again, haynes is no help.
could anyone write a DIY for the procedure? (assuming it really is a simple task.)
i've got my recent purchase almost completely tuned up and all routine maintenance done. thought i might finish with this task and then have some fun.
a couple pictures wouldn't hurt, if you have time.
