bumpy-vibrating sound

when i accelerate sometimes or come out of a corner i get this weird bumping or vibrating sound and feeling coming from the back end of my vx executive. i cant really explain it to well so i hope some one knows what im talking about

I have a similar thing, particularly at around 60kph and 1500rpm i have a vibrating feeling and noise on acceleration and not sure what it could be

Sound's like the tail shaft. Get the Uni's and the main bearing checked out.
