I have a Freelander 1, with same problem, even though mine has been converted to 2 wheel drive, so no propshaft.
The vibration is only around 40 - 70 mph on acceleration, when you take your foot of the pedal, the vibration stops and it freewheels without any vibration at all.
Really need help with this, as i dont want to pay a fortune for a garage to diagnose lots of wrong problems before finding the real fault.
PS: just had all wheels tracked and balanced.
Also noticed that when turning right hand bends the vibration seem to be more noticable.
Hope someone can shed some light on this for me.
