I think I fixed it. A few months back when I was working on the water pump, I broke a bolt from the power steering pump off in the engine block. Two shops tried to get it out but couldn't. They actually ground down some parts of the block upon which the power steering pump sits. After I managed to get the broken bolt out myself, I tried to build the areas back up with JB weld, but I guess I did not do a good job, as when I looked closely at the power steering pump today, the pump was tilted somewhat causing the pulley to not be completely in line with the rest of the pulleys. I used an aluminum plate behind the pump and now it sits properly and there is no noise yet. Fingers crossed.
