Mein Auto: 2006 BMW 530xi
Unhappy muffled knocking/vibration noise while driving

Hi I've searched all over but can't seem to find the problem I'm having with my 2006 530xi

I hope someone has an idea. Here it goes:

I hear a muffled knocking sound (one per wheel revolution) at any speed that seems to be coming from right front side of the car. With high speed the sounds turns into a constant noise (like very noisy tire). Low speed produces same kind of sound (only a bit quieter), turning left amplifies the sound, turning right makes it almost go away. All that is accompanied by a slight vibration of the steering wheel at highway speeds.

A different set of wheels (tires and wheels) did not cure the problem.
Sound does not disappear while breaking.

Any ideas?
Could it be right axle?
