Power Steering Belt Replacement- Again

Hello,

I was recently given a 2002 Subaru Outback with the 2.5l engine.

The car has sat for the last eighteen or so months in Western New York, so it needed a little bit of love to get back up and running. The check engine light is still on, and is coding the Catalytic Converter, but that's another story.

The one problem I ran into was the power steering belt. When I first began driving it, the belt was squealing pretty badly when the car was sitting still. Eventually, it began affecting other systems. I replaced the belt, and discovered the old one was in shreds- not sure how it even stayed on.

That was about three weeks ago. Everything has been fine (except that darn CEL), but recently it began to squeal again when parked and turning the wheel, very light as it started before but it seems like the same problem. I don't mind replacing the belt again, but I'm sure there's more to this if the belt has to keep getting replaced. Any ideas?
