Ok, here is what was done so far to the vehicle.
1) I relplaced the tires with Continentals 94W, all 4 tires.
2) Balanced all 4 tires.
3) Had the front end checked by dealer and local bmw car shop:
Dealer and local car shop checked the entire front end, including bushings,
and for loose arms, again found nothing wrong.
Another observation is that the car does vibrate on speeds above 65 MPH, and the vibration is felt on the steering wheel and on the bottom of my pants.
My next move might be replacing all 4 rotors, but that is expensive, and the car does NOT vibrate when the brakes are applied, if I knew that was the problem, I would do it.
This is a serious mystery that is very frustrating...a friend of a friend told me that it could be the struts, is that possible ?
I dont want to start replacing piece by piece in the front end which will get too costly.
