Rear end Vibration

[OPTIMUS]

G'Day fellas just after any clues or tips on my problem.

There is a vibration or what feels like a badly balanced wheel feeling coming from the rear of the car (can feel the wobble in SOPs), ive had all wheels balanced and aligned and all is fine, it seems to get worse the faster you go especially 80+ and feels worse if you accelerate and back off. My guess is diff?, is there any way i can test it myself or troubleshoot to narrow it down?

Cheers.

had a similar problem in my old vy.
there is a couple of rubber donuts that they use on the tail shaft instead of uni-joints between gear box and shaft and diff. (they are to help feel smoother) mine had torn around the bolt holes and needed replacing (from the twisting force during acceleration, see if it feels worse when hard accelerating up a hill)
see a tail shaft specialist of memory it cost us about $400 to do both.

I had this happen in mine recently, could be a number of things but ended up being the cv shaft. Replaced it with a new one and problem solved.
