Im getting a real violent vibration when pulling away in first gear and reverse (not all the time), it feels as if the engine is going to fall out. It even continues after you push the clutch down and try again, then stops and is ok for a while. Have checked the engine mounts by putting the hand brake on and trying to move forward and back but no movement to the engine. Have changed the drop links a few months ago and they are fine. The engine roll restrictor has been replaced in the last year. It`s p reg galaxy by the way. any info plz
