Toyota 2006 Kluger Grande 3.5 L - at about 55kph vibration

[Davo55]

Toyota 2006 Kluger Grande 3.5 L - at about 55kph or thereabouts, steady state speed, a vibration occurs like you are on a corrugated road but you're not.  The vibration stops under accel or decel or braking.  Any ideas?

Many things come to mind. 

 Wheel Balance, probably the rear if no steering vibration.  A wheel weight may have come adrift ?

Tail shaft universal joints ?

Loose wheel nuts ?

Transmission / transfer case ?

I take it you haven't been to see a mechanic yet.

Control arm bushing?

Control arm bushing won't induce vibrations but more of a knock when jostled.
