Strange clicking noise
 

Hi,

Lately I have a strange clicking noise when I turn the steering wheel to the left. The clicking noise is eveytime at the same point when I turn the steering wheel.

I found on YouTube someone with exactly the same sound:

In the comment section someone says:
The exterior of the wheel bearing oxidizes, and also the piece of metal in which the wheel bearing is put inside.
Wheel bearing has to be taken out cleaned,
Inside of the part where wheel bearing is put also cleaned, and greased.

Is this possible, could cleaning and greasing the inside of the knuckle solve this problem?
