Grinding noise from front wheel

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?
