I have a 1999 Chevy Blazer LS. In the past day or so the power steering has been making a shreaking sound, but only when I turn to the right.I thought it might must be a power steering squeal at first and added power steering fluid to the reservoir which was low. The sound seems to be generating from somewhere close to the front driver wheel though.

Got any ideas?

Check the serpentine belt and make sure it's in good shape. Also check the idler pulley for the belt and make sure it's not trying to lock up. Either could cause the belt squeal. If that pulley locks up, you'll be overheating and stopping quickly.

What about a bent idler arm?....Would that squeeze stuff enough to cause a noise when the wheel turns?

Nevermind......Noise disappeared after about 2-3 days of driving. My buddy said it was probably just one of the bushings that needed to wear itself in after it was moved a little bit.
