Steering wheel squeals when I make hard turn ???

I HAVE THE SAME CHASSIS UNDER MY 03 DISCOVERY. I EXPERIENCE A SOUND WHEN ON A TIGHT QUICK TURN. IT SOUNDS TO ME LIKE THE POWER STEERING FLUID RACING THROUGH THE STEERING GEAR JUST UNDER THE FLOOR AT THE FRONT. MY GUESS IS THAT THE FLUID DELIVERY SYSTEM TO THE STEERING GEAR IS JUST NOT ABLE TO KEEP UP WITH THE DEMAND. AFTER 40,000 MILES OF THIS SOUND ON OCCAISION WITH NO NEGATIVE ISSUES I DECIDED TO LIVE WITH IT.
