well then its almost certainly an out of balance drive shaft caused by a worn CV or UJ in the front axle area.
it might be a dead engine mount as well, but that's easy to check. Is the vibration more speed or RPM related?

I am getting a new set of tyres soon, to see. but then will plan to change the left and right mounts, i am feling the mounts more, sometimes cant figure if it from the front or the back. I dont think to get to the drive shafts unless this doesnt work.

I had a similar problem with vibration at low speed and when turning checked just about everything renewed most everything . chating about it in pub and a guy sitting close gave me some advice , he asked me how old the tyres were and what brand( they were michelin ) then said he suspected that even though they were more than legal that the tread was delaminating from the underlying belt . Cut a long story short thats what was happening the actual tread was moving side to side on the belt when turning and was lifting from the radial belt in a straight line at low speed,

That's the next thing, tyres.
I put the prop-shaft back on after replacing the VCU carrier bearings(95% sure its all back the same as when it came apart) , and now about 50KMh the car shakes, I have noticed on a left turn whilst with power it stops shaking, not so on a right turn.
The tyres are tread depth legal, but look old on the side walls, so they are to be changed very soon.

Hi All, so with a new set of tyres, the fault seems to be more constant, above 80kmh there is the shake, so far havent been much above that. due to my next post, problem

not sure what you mean by that" rotating the damper"??

This sounds like a "death wobble", a small amount of play will rsult in increased side loading on the steering, at a certain speed the vibration will hit 1st mode of the natural frequency (resonance) and be amplified to the point of causing the whole vehicle to shake violently.
If a freelander has them, it'll likely be the panhard rod bushes that's generating the play, it will be well worth checking all of your steering joints as well for damage as a result.

Nope- not at all, the VCU has 2 carrier bearings with 2 bolts each thats it.
