My understanding (and experience) is that it can be locked on the move, up to 40km/h.Can you really lock the center dif at speed? I thought neutral had to be engaged first (obviously can still be rolling in neutral)

Do you engage your center diff in drive, or always switch gear into neutral first ?My understanding (and experience) is that it can be locked on the move, up to 40km/h.
I’ve been locking the centre diff in Drive (up to 40km/h) although I would note that in the Getting to Grips with your Grenadier video, the instructions are to stop and engage Neutral before shifting.Do you engage your center diff in drive, or always switch gear into neutral first ?
NA manual: "The center differential can be locked and unlocked with the transfer case selector while on the move so long as the axles are rotating at the same speed"I’ve been locking the centre diff in Drive (up to 40km/h) although I would note that in the Getting to Grips with your Grenadier video, the instructions are to stop and engage Neutral before shifting.
Indeed. As the manual states (always read the manual , even if it has been written in a peculiarly wordy way!)You can engage centre diff lock whilst moving at low speed but to change between high and low you need to be in neutral and stationary.
Or even better: lock before enteringRough terrain - stop first
I shift on the bitumen just before I hit the dirt , otherwise my wife chimes in to remind me!Or even better: lock before entering
In my area its like so - bitumen -> Gravel -> dirt. On Gravel I leave centre diff unlocked but when moving towards the dirt the centre lock will be set while in motion. Unlock the same.I shift on the bitumen just before I hit the dirt , otherwise my wife chimes in to remind me!
A bit more than a pin in a hole, eg locking collars and stuff, but close enoughThe central diff lock is essentially a spring loaded pin that lock both outputs of the transfer box together. Power is distributed evenly to both propshafts/axles when it is engaged.
In simple terms. To engage a spring loaded pin is pushed into a hole, to disengage the 'push' is removed and the spring draws the pin out.
To get the pin in the holes have to line up and to allow the pin to get out there mustn't be any sideways grip on the pin.
The holes are in alignment when the front and rear axles are rotating at the same speed.
In this happy state the pin can be pushed in and will pull out easily.
Sometimes just lifting your foot off the accelerator (so the car is rolling) will be enough to release any pressure in the diff and it will lock/unlock easily, braking accelerating and cornering will all create pressure on the pin stopping it moving (in or out).
If you leave the pin in and drive around on the road (or other grippy surface) with the CDL 'locked' then you will increase the pressure on the propshafts which may damage the diff.
Modern locks are better than the older versions, for example in the older Land Rovers you would often need to stop and reverse for a few yards to get the CDL pin to spring out and disengage the CDL.
200 Land Cruiser has a Torsen limited slip center diff that is also lockable.Automatic lockers are for mild use. They lock and unlock at will, they are not ideal. In the case of the GM G80 almost useless. Manual lockers are next level. Want top level? The Power Wagon has a rear manual locker that acts as an LSD when off.

But no factory front/rear lockers. It will run you somewhere in the neighborhood of $5K USD to get them aftermarket.200 Land Cruiser has a Torsen limited slip center diff that is also lockable.
Thats a center diff, which is fine but that is AWD for street use. A rear differential that acts as an LSD when off allows you to travel further off road before having to lock up, which is nice. Frankly the Power Wagon needs it due to weight going up hills. But I believe Rubicons have it as well.200 Land Cruiser has a Torsen limited slip center diff that is also lockable.
"acts as an LSD" confused me. I figured it was not a mechanical LSD, but electronic, using brakes.Thats a center diff, which is fine but that is AWD for street use.

It is a fair approach. But you should think about locking the central diff anyway in slippery areas as it (unlocked) might suffer from spinning axles. @AWo explained somewhere why this can be important."acts as an LSD" confused me. I figured it was not a mechanical LSD, but electronic, using brakes.
Looked it up. Power Wagon has a "Torsen-style" mechanical LSD rear diff that is also lockable. Same as LC center diff.
Personally, I never use any traction aids until I start losing traction. This way, if I get stuck in 2wd, I can then pull out the big guns, engage 4wd and unstick myself.
Center diff open and start to slip... Lock center; extract self.
Open front, rear... You get the idea.
This might have to do with my local terrain. Mud is the only obstacle I regularly deal with.
Need to cross this field to turn on a pump?
Bad idea to start that adventure with all traction aids on only to bog yourself down to the frame a mile from the nearest tree.
