Perhaps a more simple idea would be to take the shafts of,and take them to a prop specialist and get them checked and balanced.The MB vitos suffer with driveshaft problems to.
Not the whole driveshafts have been replaced, only the inner parts with the tulip. But AFAIK shaft unbalance would cause vibration at the same frequency the wheel of rotating, in my case the frequency is clearly three times the rotational frequency.
- when the car is cold it shakes less (strange) - didn't find the logical connection for that reason
Out of curiosity I did a search for Vectra C vibration. A fair few threads to be found, but this one seemed most interesting.

Seems that balancing the wheels using the centre hole does not work well, needs more expensive kit that balances it by mounting it using the stud holes. Worth a try.
