Had the same problem with my 91. Took it to my local mechanic and they used a special machine they have to siphon and clean the pump and the whole steering system while the car is running. They then replace the old fluid with a synthetic oil. The pump was super quite after this but because of the idle control valve being bad it sucks some of the oil out. I top it up with Dexron III which is compatible with the synthetic but now that I am getting more Dexron in there the pump is again starting to make a small amount of noise when it is cold but only for a few seconds after the car is started. The mechanic told me there was a lot of "debris" in the old oil they sucked out.
