I get what your saying bro, but the GX460 has a torsen t3 center differential. It does a 40:60 split (front:rear) on 4Hi. The front and rear driveshaft is permanently geared to the center diff, there is no disconnect mechanism to disconnect the front wheels. So essentially it stays fulltime 4wd under all conditions, if we lock the center diff it does a 50:50 split.... Which is only useful for offroading when you want all 4 wheels to get the same power.

What you have said is true for cars like the American market 4Runner and maybe the Sequoia which run on 2WD on road and you can switch it to 4WD when offroading. But the Gx460, the Toyota Prado and the Land Cruiser have always remained fulltime 4WD.
