Hello,
I was unable to find an answer to my question so i decided to start a new thread.
For quite some time, i'm experiencing rustle noise from my power steering pump.
The weird about it is that it's only happening while i'm NOT turning the steering wheel (it's not that kind of classic grinding noise)

Basically, when i start the engine, within a second or two the noise is present, if i move steering wheel to any directions (to put some load on it), the noise is gone.
During the driving, the noise is present as well mostly due to fact that wheels are not under that much of a load from PS

I have done following already:
Flush the whole system with new fluid (right amount, right specs)
Replaced a PS pump with used one

Non of these worked so far and i wanted to know if some of you have experienced something like that already and what would be the next step.

Thanks in advance!
