just to add to this I replaced the power steering belt a while back and it was slipping making a high pitched noise but it stopped after a while ,so it probably was slipping all along that contributed to the possible failure of the pump.I added what I thought was power steering fluid(actually I mistakenly bought AFT repair fluid ) and the pump noise stopped until it leaked out again in a short time.The fluid that is leaking doesn't seem to be coming from the pump itself but lower down near the rad and laying on the plastic shield. Thanks P-Funk! ,I was hoping it wasn't the pump itself but just a leak ,I'm hoping your wrong. Preferio I don't know what fluid cavitation is ,thanks though.Can the pump be repaired if its the problem with a repair kit from rock auto
