Power Steering Pump?
My car makes a high pitched squeek when you turn it on and sounds like a pulley that needs lubed. I tried lubing pulleys but no luck. It squeeks for about 15mins. and then goes away once its warmed up. I put a little bit of stop leak in the p/s resevior and it quieted things down. Checked everything else and all is good. No goofy things going on with the steering if that helps.
