My power steering went out. I took it to the Chevy Service Center and had them look at it. They told me it was the power steering motor. I decided to do it myself. I bought a new motor from them. They told me Chevy no longer makes brand new ones and I would have to get a refurbished one. It was simple to put on and the power steering seems to be working. The problem I am having now is a whining, or squeaking noise that the car makes every time I turn the wheel. This can be both while driving and sitting in park turning the wheel. Do you think they gave me a bad Power Steering Motor? It hasn't kicked off yet and seems to be working. Is it possible I put something back together wrong? I need help. I cannot stand the noise. Thanks.
