I have a whine on my pump. Recently had the high pressure line replaced because it was shooting fluid into the fans which in turn sprayed everywhere when the fans came on. I didn't hear a whine when I left (I think...maybe I was happy just to get the hell outta there), but two days later I heard it big time. I bleed the system again with the wheels off the ground etc..but I still hear the whine. The pump I think is working b/c the return line shoots fluid out pretty hard, but I'm no mechanic so something else could be causing that. Someone told me it could be the water pump, but I told him I placed my hand on the PS pump while someone steered and it felt it. Could the water pump send such a strong vibration and the PS pump vibrate also. A whine means the pump is failing or failed. Man I just want to autocross this Saturday and replace the pump the following weekend.

 

mine did it all the time like you said till i put on some wd-40 and belt dressing and it went away. that was about 3 months ago and it hasn't went out and i've takin it around the twisties since then with no problems
