Christer,
I would not drive the car in such a way as to create the vibration you are describing until you get the issue fixed.
I am not a mechanical engineer but I know things are designed to take stresses in a certain direction and a certain amount. If you are getting stresses perpendicular to the designed direction you could have a failure of a half shaft yoke which would send the broken halfshaft flying around, doing severe damage to your sheet metal and possibly the ZF.

I have not disembeld the shafts but previous Owner may have? I belive
this could be the issue and I guess I need to dig further into it. At
the same time I will Inspect the Engine joints to be secure.A
Thanks for all your advice!
Best regards ChristerA
I would defenitly come back when the issue is solved!

Christer,
Did you dismantle the two halves of the driveshafts? If so, and you
didnat get them assembled exactly as they had been before, you could
have easily created an imbalance or out-of-phase condition.
