Lots of people have this problem. I too don't remember them being this way new. I recently replaced my ps pump and rack and pinion. Made noise from first start up. After driving a couple weeks and doing all the normal checks, I couldn't get it to stop. Then I checked my fluid again, it was a little low, added more, and it was quieter for a while. I'm wondering if the fill line on the pump housing is not an accurate read. Maybe if we overfill it a little all our problems would go away. Jk. Also maybe after driving a bit, the fluid works out more air bubbles and stuff, idk, just a thought.
