Hello,
I started to notice humming noise which gets louder and "longer" with higher speed. But frequency changes very very little and pitch not at all. I noticed humming disappearance when i turn steering wheel to the right even just lets say 5 degrees. I' asking because all wheels don't have play horizontal or vertical axis. so i'm a bit confused.
maybe someone have some advice ?

Thank you.

Tires make a speed and steering angle related hum when worn.
When did you last rotate the tires?

It was wheel bearing. test driving with expert helped. he noticed a little vibration and he quickly diagnosed the problem.
