I've got steering noise at slow speed on my '95. At first I thought it was the tires squeeking on the pavement, but no, it's coming from the pump. The Ford tech explained to me that the mechanicals in the pump wear and when the reach a certain wear level they make noise. It's fairly common.
He explained that the pump was working, just making noise. I'm gonna live with it for a couple of weeks, then swap in a new pump....
