This year I heard a slight whining noise at the rear right left side.
It has comes and goes with every turn of the wheel and it does not matter if I am on a curvy road or straight run. The frequency of the oscillating, whining sound is solely depending on the speed of the car.
The whining sound has become much louder over the summer.
As I think it comes from the left side I was checking if I can find something wrong at the left rear brake but nothing was wrong there.
Also I checked the differential oil level and all is good here as well.

My suspicion is that this might be the wheel bearing?

What do you think?

Thanks, Martin
