I have been noticing a slight but annoying grinding noise in the right front when I turn the wheels. I checked the ps fluid level awhile ago and it was fine. No leak that I could see from above or on the floor. Do I just need some lube? (Someone say yes, please.) The dealer checked the front end when doing the coolant change and thought everything was ok.
GM's powersteering pumps are infamous for being loud at times. I wouldn't be too worried about it, it's unlikely that it would escalate into a serious problem. Though it wouldn't hurt anything to change the power steering fluid.
