R33 Gtst Vibration

[BANGN]

my 33 has a harsh vibration I cant seem to pin point.

its nothing like a steering wobble or wheel ballance issue. The feeling is like someone has attached a vibrator to the chassis and it only does it under load.

Boot it and there is no vibration at all, doing 50km/hr, put it in 3rd gear and plant it and you get the vibration. Put it in 5th at 50km/hr and plant it and the parcel shelf starts vibrating.

I have checked the exhaust incase it was resting against something and that failed. Gearbox mount doesnt "appear" to have perished.

It will do it in any gear underload and i know the clutch is rooted, the box is quiet as a mouse spinning in neutral, doesnt have any roll over noise. Not something I have experienced before so im hoping someone has.

im just hoping its not the gearbox, I wouldnt of thought so as like I said, the vibration under enough load can rattle the parcel shelf

im waiting for a video I have uploaded to youtube so once thats uploaded I will post it here

cheers in advance
