Grinding noise from front wheel on 2000 Mitsubishi Montero Sport

I have a grinding noise coming from my front right wheel when the car is moving forwards. Any ideas what that might be? Wheel bearings perhaps?

Does the noise change when braking? If so, how?
The noise does change, when you come to a complete stop the noise finally stops. The grinding seems to start when you hit a bump. I'm a somewhat of a decent mechanic, for sure it is not the brakes, changed the wheel bearing, for got the differential bear. I don't think CV, as there is no clicking when you turn either way. any other ideas.
Did you find what was causing this? I have the same problem/symptoms occuring with my Montero Sport.
Just replace the pads with a quiet and low dust quality pads and now grinding noise when applying sudden braking.
What's the problem?
