Okay, here's the full story. If I start my car up when it's cold, roughly 7/10 times it will make this real high pitched loud sqealing noise. I'm pretty positive it's the power steering belt. Anyway, once my engine is warm, it doesn't squeal... unless** I turn the wheel all the way in either direction once the wheel stops turning I can see the power steering pump lock up and then hear it squeal. I, figuring it was a power steering pump problem replaced the pump, and it still does it. Do you think the used power steering pump I got was bad too, or is there a different problem I'm missing. I'm open to any suggestions. It's really loud and annoying and I want to get it fixed asap. Thanks all!
