Has it had freewheeling hubs fitted to the front?
This sounds like what would happen if the hubs weren't locked.
or a broken front axle.

Hi reddeer,
Check a plug located on the rear of the transfer, in about the 1 o'clock position looking towards the front of the vehicle check for dirt or moisture in the connect. It unplugs in the horizontal plane and has a yellow and blue/black wire attached.
Try disconnecting this and see if it makes a difference.
It Stops Centre Diff Lock being engaged automatically when low range is selected.
Hmmm

reddeer,
Unless manual locking hubs have been fitted it sounds like you have a broken axle, if it was something more serious you would probably hear about it. Although you say 'bought recently' was it like this when you bought it?
Try this, without the engine running, put it in any gear in H4, centre diff Not locked. Crawl under the vehicle and see if you can turn the front drive shaft. If yes you know there is something broken or missing in the front diff. If not then try turning the rear drive shaft, if this turns then something is broken or missing in the rear diff.

Another option I have used is select any forward gear in High range with CDL off release clutch and if no forward motion, check underneath which tailshaft is rotating. If front then axle, c/v failure or diff problem. If rear then diff problem or damaged rear axle. I had a broken c/v centre with no noises but would jam on the axle spline giving drive.

Inside the front hubs, there is a splined component (don't know what it's called) that the axle slides into. It's bolted on and replaceable. These have been known to wear out allowing the axle to rotate with no drive to the wheel. Do some of the checks outlined earlier and if in the front, that's the first thing I'd be checking. Surprised there's no noise though if something is worn or broken.

Cheers
