I think my patience is running out. There have been very few moments when I enjoy my freelander.

So during this winter my car developed a rumbling and vibration. It is related to speed, not acceleration. Present both under load, and when just coasting. Very subtle pulsating rumbling in low speeds, constant loud vibration and noise at 90 kmph, big vibration over 110 kmph. The pulsation is more distinct when cornering both left and right.

Since the car developed this, i have
Check alignment
Changed wheels and tyres
Checked all wheel bearings - no play in them
Removed propshaft

The noise is still there.

Additionaly : Two years ago (prior to this vibration) i replaced all wheel bearings, all suspension parts (including struts), front PTU, rear subframe, rear diff.

Now i am figuring out what to do next, my plan would be :
1) Install new front drive shafts
2) Replace front bearings
3) Replace the PTU again
4) burn the car down

Any ideas towards which of these things I should do first would be appreciated.

I believe there are microphones that you can strap on to various parts of the chassis, that may help pin down your problem.

Front anglebox, when knackered makes the car drive very badly and makes a noise under the dash, it also will destroy the rear diff. It did my 2009 car. Consider also the propshaft, and /or, centre bearing, or all of them. Best remedy is often to turn up the radio, until the car stops one day, t will be obvious then what the real fault was.
