Guys, my problem is different
my car was lifted, front wheels standing, back ones rotating and the vibration was there.
We removed the wheels and tested again (just brake discs rotating). The vibration is still there and you could feel it in the the steering wheel despite the fact that the FRONT wheels were not rotating, the whole car was vibrating.
One more thing, it is not related to the engine or the gear box:
it vibrated 7th gear at around 2100 rpm or 6th gear around 2800 rpm, it is simply from a certain speed that it starts vibrating....
I am thinking or drive shaft, half shaft.....U joints,, dont know
