Advice sought! 107K Ex35 - I don't have much in way of surrounding facts, other than it appeared to happen when I broke hard and turned right (having a little fun). Now it's as though there is zero power steering - so, turning at extreme low speed is a lot of muscle work. At zero speed, impossible. I had a week or so earlier added PS fluid at cold temp to the top of the mark. But now, I see that the reservoir is a little bit over the line. Would too much fluid cause this? How to begin diagnosing? Thanks, y'all.
