So after driving in 4hi/lo I'll need to reverse a bit then put it back into 2wd.
But is this only when in auto on the hubs or the same if I had them locked.

Reversing in 4 low or hi should be no dramas. I used to reverse a mates fishing boat up a slightly steep-ish driveway in 4-low in my Nav. Makes it easier on clutch too.

Nah put into 2wd then reverse. It forces your hubs to unlock, otherwise they may still be locked while you drive away.

If you're happy and you know it tap a post!

..... found this out the hard way when stuck in a muddy rut unable to get any backward movement, the auto hubs had disengaged. Get out in the mud and snow and lock the auto hubs, rearward movement is then available. This resulted in my rule that whenever I am in sand, snow or mud the auto hubs are manually locked for the duration of those conditions. (Of course normal rules about not using 4wd on tar or "hard" surfaces apply)

Yeah its called wind up, you need to reverse say 50 mtrs, sometimes more to "UN WIND" the drive train.
It releases all the tension { Pressure if you like} from driving forward.You have no doudbt heard the term back lash
effectivly wind up has removed all your back lash, reversing unwinds your axles releasing the tension, restoring back lash
and allowing you to select 4 hi etc, hope that made sense. Wind up is wind up be it hubs in auto or fully locked IMO

I don't have auto hubs so can only comment on manual locking hubs.

Hubs are still locked;

When it is no longer necessary to use 4WD I select H2, most times the 4WD light is still on, I drive forward and most times it goes off, if not just do a left and right on the steering wheel the transfer case disengages and the light goes off.

Don't drive it hard, just normal driving on any surface. Never had a problem with it disengaging. Once the light is off the wind up is gone so drive away.

50 metres plus is a long way TD!

Does it happen with a manual gear box or with an auto one?
Thanks

I don't think the gearbox makes a difference just the auto hubs?

Do you know what back lash is? It doesn't matter whether your in 4wd, 2wd hubs locked or unlocked, as soon as you start to drive (engage clutch) the back lash has been taken out.

Wind up is completely different. If you constantly drive in a straight line when in 4wd with no wheel spinning then it shouldn't occur (unless your Tyres are bigger on one axle). It tends to happen when steering and in 4wd, as everyone knows the outside turning wheel has to turn faster than the inside wheel so the front drive shaft wants to spin faster than the rear (wind up).

So unless your doing NASCAR style tracks the wind up should be minimal?

I to select 2wd when not needed, but as soon as I leave the formed road/track its 4wd as it saves tracks and keep the nicer for longer..
