Yes I’ve seen that video when I was doing my research before I purchased my first Patrol. He didn’t mention anything about locking the hub if you want to switch to 4H while doing 80km/h. May be it’s an assumption that hubs must be locked!

The owners manual also says nothing about locking the hubs. However, when I first tried to shift from 2H to 4H with hubs on auto, one could hear the grating of the splines. Also, the shifting was difficult (as you also have noticed). Further reading on the matter indicated (to me at least) that shifting without the hubs locked could cause issues. Since there is really no difference in driving the vehicle in 2H with the front hubs locked, I prefer not to take chances, and I lock my hubs on the occasions where it seems as if I may need to shift between the two on the move.

Ian, I’ve also noticed this in my recent trip. Tried shifting to 4H while driving when the hubs are on auto and I could hear a noise..so didn’t take any chances.

It’s funny the manual also didn’t mention anything about locking the hub.

Saw the video again. If hubs are locked then we could shift to 4H at upto 80km/h, and 40 km/h when on auto.
But that’s on manual gearbox.
