Hi carnut,
I've had the power steering pump replaced and the smog pump. The noise doesn't go away, it sounds like a noisy bearings to me, but what do I know. Its getting louder and louder as time goes by. And I've taken a video of it, used a stethoscope, which by the way, makes a number of parts sound really noisy. In the video I thought maybe the bearing on the generator might be the culprit, but the remanufactured power steering pump, which I got from Napa parts, and was just installed, sounds pretty loud. Can I send you my video? offline from the forum? My mechanic can't figure this out. I'm going to try someone else, but my mechanic owns a couple of these old caddys and knows alot. The dealer charges $200 just to look at the car. Maybe I should go that route and give it up. Any further thoughts?
