no simple noob answer, PLZ HELP, wineing noise from alternator,but Options

[mandrek]

well about a month and a half ago, I was getting really bad noise from my alternator, and a sort of electrical burning smell, unlike rubber, and it came down to my just replacing it (and the belt). Apparently the bearings went bad. But the thing is until the noise (a grinding (like a metal on metal cricket chirper) got really bad, it only made noise when I turned the steering wheel. (When the power steering was being used) but the noise would go away after a lil bit of time w/ the car running. Until that is the alternator's bearing ground down, and it made the noise the whole time.

Now it's a month and a half later, and the east coast is having its first major cold days of winter, and my car started doing the noise again. (And the smell came back too) which worries me cus I just shelled out the money to buy the new unit.

So my question is. Could it be the power steering pump going out on me, or slugging behind? And thus putting additional stress on the primary accessory, (the alternator)? The car is a 95 ST and has about 100K on it. I picked it off my brother as a hand me down, and at that point I changed almost all the fluids. (Tranny, oil, coolant, brake's) the only thing that I didn’t do was the power steering.

Should I get a new pump,flued,filter,belt for the power steering? And get my alternator looked at?? Is this the right course of action?

Plz only positive opinions, and helpful comments.

Thank you in advance
