jeffro Posted July 12, 2011 Report Share Posted July 12, 2011 Good evening all. I come to you in a time of dire need. Saturday my Power steering pump started whining. Whether it was driving in a straight line, or turning the steering wheel, theres a constant reminder of an issue while the engine is running. I checked the power steering fluid levels and it was okay, so its not leaking. I did however notice that there was tiny bubbles inside the resevior when the car was running. Are these the symptoms of a bad pump? The whining is definitely coming from the pump. The car has 89k miles. 2002 Ford Focus SE. Thanks in advance.

TurboRust Posted July 12, 2011 Report Share Posted July 12, 2011 double check for leaks, sounds like air is entering the system... turn the wheel all the way to the right against the lock and turn the car off, let it sit for 15 minutes.. this should remove all air from the system. unless there is a reoccurring leak Quote Link to comment Share on other sites More sharing options...
99FLHRCI Posted July 12, 2011 Report Share Posted July 12, 2011 AllData says to do what Derek says BUT, once it is at lock and shut off, apply 15 in Hg to the system for 5 minutes. Then repeat with the wheels all the way to the left. If noise is still there, repeat. If the noise is still there, let it sit overnight and then repeat. It also says to make sure you are using Mercon V fluid (not P/S). Quote Link to comment Share on other sites More sharing options...

CRed05 Posted July 12, 2011 Report Share Posted July 12, 2011 Ford power steering...that's what they do, they make noise. 15 in Hg = 15" mercury = vacuum Quote Link to comment Share on other sites More sharing options...
ansonivan Posted July 12, 2011 Report Share Posted July 12, 2011 +1 for all the advice above. One other issue I've seen cause a noisy pump - plugged filter which is built into the steering fluid reservoir on some cars. The added restriction was causing the pump to starve for fluid.

jeffro Posted July 12, 2011 Author Report Share Posted July 12, 2011 holding the steering wheel on the right side wheel lock did nothing. Im just going to replace the pump. Quote Link to comment Share on other sites More sharing options...
