VF SS rear end noise

[Will1996]

I have a series 1 Vf SS. its pushing 315rwkw, Its a stock diff and stock drive train. I recently noticed a noise and shake coming from the rear end of the ute when I would aggressively accelerate, I can feel it through the whole car as its very excessive and is getting worse. It does only do it when the cars pushed hard, fine under normal acceleration. I have no idea where to start looking and hoping someone else has had an issue like this before and if so what was the outcome?

Check the condition of the rubber couplings on each end of the propeller shaft.

BlackVXGTS is probably spot on, here's a link for education purposes also.

Looked at your diff bushes?

Assuming wheels are true and balanced i,d suggest starting in order from centre bearing, diff bushes and if axel tramping probably lower control arm bushes.
