I really neglect checking power steering fluid for a long time, last week driving to LA, at park or low speed, the steering feels heavy and the noise started to sound really bad, I thought my steering rack is needed to be replaced. Came home, checked the oil reservoir, and sure enough, it’s on below the minimum mark, filled it up with CHF 11S  mineral oil and the noise was gone immediately.
