Whistling sound

Hello everyone, my friends vehicle 206 1.4 hdi 2007 model when I turn the steering wheel to the right, there is a whistling sound, what could be the reason for this?

I think a rot-balance will be hypothetical and a lie what we say from here, there is nothing there they tell you.

It is said that sound is normal when the power steering is broken right or left. I saw it when I researched it.

All right, not even when broken, it feels like a whistle.

I call it the steering pump. turning the steering wheel, there is not much sound from the front team.

I think so too my brother, I will go and let me write the result

teacher, if the problem is in the pump, zero imported 280 TL like the original 750 TL sonerkyl 2017-02-20 13:21:15

How many masters I went to, one said the bearing, one said the belt, one said the pump, one said the steering box, the service says we change everything, what do you suggest?

I think getting used to the whistling sound ..

teacher, first of all, replace the front set z rot - tie rod - tie rod - finally go to the steering pump.
