Two other things to diagnose;
- Is the Power Steering fluid "frothy" if so you need to replace the PS tank O-ring, there is a right up in the How-To documents at the top of the page.
- Next is to take both of the front belts off. Start the engine, if the sound is not there we are close to identifying the problem.

With the belts still off, spin all of the pulley's and idlers, are any of them hard to turn or make a slight noise? That's probably the one.
