Subaru Outback 2007 120k
I had a power steering noise that did not want to go away
I checked the rack boots they are good, Next I did a fluid flush and used "seafoam" turning became smoother, noise the same.
Next I tightened the belts, noise improved.
Next I changed the O-ring on the return hose no noise on start up or turns unless I have to lock the steering wheel
not sure what I should do next change to eliminate the squealing completely
should I change the hoses or is it a pump problem, or maybe rack?
