I have a 2010 Ford Edge AWD. It has 222,000 miles on it. The motor was replaced a few years ago with a 2008 with roughly 108,000 miles on it. Not sure it matters but I digress, all steering makes this awful whining noise. I noticed it several weeks ago put 1 pint in, it didn't get much better. Checked it days later its almost empty again and frothy, I'm told add another pint there is air in the system, I put another pint in it. It sounds so much better. Another week goes by, it starts to whine again. Sure as shit the level is low, add another pint. At this point I have put in 1.5 quarts of power steering fluid over the course of roughly 1 month. Yesterday it begins whining again. I park in the same spot every day whether I am at home or work and there is NO evidence of a leak anywhere. No marks in my drive, no marks in my spot at work, nada. Where is it going? All other fluid levels are fine, no other systems seem to be affected, its not blowing out the top.
