When i accelrate or genarlly driveing along my car vibrates is this possibe driveshaft gone ? I dont think it a wheel bearing as when jack my car up and spin wheel i hear no knocking ect ?

It's possible that one of the inner drive shaft bearings has gone, but unlikely unless accompanied by noise.

I'd start by looking at wheel balance or a wheel out of true (curbed badly and bent).

Where do you feel the vibration? Through the seat or steering wheel?

The other important question is the frequency of the vibration, does it change with engine speed or road speed?
