Noticed slight vibration after tire rotation and balancing at MB dealership. Got a refund from the dealership and found a shop with the hunter 9700 machine, did not fix the vibration, it got worse.

Took it to another shop (they sell their own tires as well) with the Hunter 9700 machine, one tire had to be rotated on the wheel (slip). Road Force feature of the machine pointed out the imbalance.

Vibration gone. A shop may have the Hunter 9700, but they may not be using all the features of the machine or know how to use it properly.
