This is on a '96 s10 2.2l. Whenever I near full lock on a right turn, I get a loud squealing noise coming from somewhere in the front of the truck. It sort of sounds like something is rubbing at full lock when I can hear over the squeal, but I am not sure on that. I have checked the PS fluid and I do not see anywhere that the tire is rubbing on either the tire or frame. Any ideas on this one?
