Re: Wheel Bearing?
If the EM1s have heat shields for the disc brakes on the front it could be that. I had a rubbing noise on the front end of my EM2. It would do it going straight, but it would get worse turning left. Turning right it would completly dissapear. It turns out that the heat shield was rubbing the rotor. I took the wheel off to inspect and bent the heat shield back away from the rotor and the noise went away. It might not be it, but its worth taking a look at.
