My Ride: 2004 330ci six speed
Hi Everyone
Hope this may help other Fanatics, My 2004 BMW 330ci's power steering all of a sudden started to vibrate when trying to turn wheel. Also got the screeching sound. Took it in to trusted mechanic. He checked it over and said it was the pump. I said before you install new pump clean and flush reservoir and lines for power pump. He call back says pump is working and returning ATF to reservoir. He stated must be the rack. Ok grabbed new pump and begin search for steering rack. Made one stop paid bill re-start vehicle and noise is gone vibration is gone vehicle steers great. Point is a good clean and flush should be performed first. Of course if you take belt off power steering pulley and pulley can be pulled away from pump then you need a new pump. Hope this helps. KKB
