When 4 hi or low, can you go in reverse for a period of time

Yup no dramas
Drive as normal
But..... You should Lock your Auto hubs or they may disengage.
I remember reading about binding gears or something and can't remember what that was about and this thought came to my head.
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.
..... 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
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..

Yes. When on loose surfaces the Tyres can slip/spin.
Hijack.
Is it imperative to always let the glow plug light to go off before starting.
Cos the Missus never waits for the glow plugs to warm up.
What happens.
Just takes a bit more cranking to start it, no real damage but I guess it would decrease the life of your starter motor?

Hijack no.3.
What does a heavy duty valve body do/ help on a transmission.
@ Mego PM Drew he has done all those mods to his auto.
Makes the gear changes short and sharp, nice and crisp and clean. Helps hold the gear. Increases engine braking slightly.
Significantly reduces "flare".
It's said to increase the strength of a gearbox too. By fitting one to a vehicle (and changing nothing else)with the tb42 engine it's said to increase the strength of the box to be able to handle over 3 times the power of the engine.
Ideal for towing.
I was amazed at how much difference it made. Changes gears like a sports car.
If roosting in mud, it can even change up a gear without stopping the roost!
Re. Auto hubs
Never had them. If the advice is to manually lock in auto hubs whenever in 4wd terrain, what is the point of having auto hubs? When are they useful?
I love it hijacking your own thread lmao
The Nissan auto hubs are good while they are working, when they get a bit worn they start randomly unlocking and relocking, usually at the worst possible moment. That's when some people remove the auto lock part of the mechanism so they only work as a manual hub.
I just manually lock my auto ones before I go out to get the grease moving etc, Never have bothered relying on the auto side of them.....
Self hijack.
LSD. Limited slip diff
Would any one like to explain.
Long story short its supposed to spin both wheels at the same time if for eg 1 wheel is on gravel and the other on concrete the wheel with the least amount of traction ( on gravel ) would spin if it where an open diff but the lsd will engage and spin the wheel with the least amount of traction at the same speed as the one with traction ( on the concrete) so you maintain control. It slips when you turn a corner without accelerating so the inside wheel can spin slower than the outside wheel so you can have a better turning circle.
Clear as mud ??
Thats right lsd is like a locker when you accelerate, single spinner is an open diff
So locker and lsd do sick skids like this

Open diff aka single spinner does this
Attachment 32799 see only 1 wheel spinning
