I have a '01 Grand Caravan and today when I started it, it was whining rather loudly. It continued when I accelerated, only to get louder, and then I noticed my steering felt sluggish. I ran my errand and by the time I got back home, the whining had died down to only when I turned the steering wheel. And the steering wheel became very stiff almost like manual steering. Does anyone know what kind of problem I am looking at?
