Bad vibration

  1. #1
    Iv got a bad vibration the dash vibrates everything and its getting to me now. It started a couple of weeks ago i fitted new driveshafts and it drove fine then the next day i drove to the end of the road and there was a loud crack and its been like it since that. I have i replaced the gearbox mount under the battery and that helped a little but the others done look worn and that one did. Any suggestions? I have been told it could be the gearbox actually knackered?
