Vibration at 120

[AndriesS]

Yesterday on a really smooth piece of tar I noticed I had a vibration coming from the rear. I've not noticed it at slower speeds yet and it only happens on a trailing throttle. I.e. driving 120 at part throttle I don't feel anything but letting go of the throttle it starts.I quickly checked the U joints with a screwdriver and there was no play. Any ideas?

Hi. Check upper and lower rear suspension arm bushes, rear pan-hard rod bushes while you at it.

Rather keep speed at 118km/h

Thanks, I haven't had the opportunity do drive the same piece of road and will try in the next few days.
