[Biturbos4] High pitched, squealing sounds, when turning steering wheel when driving

[Witte, Michael J (HPFS)]

Sorry to bug you with this. 
 
This started all of a sudden, yesterday afternoon, on my way home from
work. Every time, when I turn the steering wheel more than say 2-3
degrees, this high pitched, squealing sound, coming from either side of
the vehicle, depending on which direction I steer to. Doesn't matter
whether its low (10mph) or higher (35mph+) speeds. I performed a couple
of emergency stops, to ensure nothing got stock in say the rotors.
Rotors look clean, plenty of pads left as well. Checked teh power
steering fluid, not a problem either. Sound like metal scraping metal,
but I have not clue where to look/what to look for. 
 
Any ideas ?!?
