WOW-wow-wow-sound from front wheel

Hi! Yes, it sounds like a tired wheel bearing, but I dont think it is. The wheel bearing was changed for about a year ago, and the car feels normal but the sound is still there. Especially from 50-100 km/h.

The ESP light and the (!)-sign has also come on from time to time. Related?

Something is rubbing. Is it possible it could be something different than the bearing?
 
maybe its just tyres?

if your minded I would swop the front to backs
and see if its still there.
as you jack up check for tyre wear and rock wheels top to bottom as its a good guide for wheel bearings being worn
 
The tiers look just fine, so I didn't swop them, but I did rock the wheels from top to bottom and could not feel any movement. However, I think I located what makes the sound. The brake pads touches the brake disc completely only once per rotation on the drivers side. Obviously that would bake a Wow wow wow sound when the wheels are rotating.

Is it possible to adjust the brake calipers more in line with the brake disc, or could it be that the wheels bearing is mounted off in its housing? Or a crooked brake disc? It is brand new, so that would be strange.

What do you think?

Cheers!

I'm no mechanical genius but if nothing else on the car has been changed it could be the most obvious thing. The new disc itself might be defective. A garage should be able to check it's running true with a dial gauge.
