The buzzing sound that comes while turning the steering wheel

A buzzing sound is coming as my friends spin the steering wheel in my partner tepee. Friends say that this problem will be caused by the steering pump. How much is this steering pump. Pejo I will have it at my own service on 28 January. I am waiting for your suggestions whether I have my service or master. What do you think comes out as a price ...

Get well soon. If there is a master you know, first take a look at the master, then go to the service. When you go to service from nothing, you will have an idea.
