I am assuming that the "bogged" that Ross refers to is a vehicle's inability to proceed due to adverse ground conditions? Cheers

Something us Patrol owners are yet to experience.

Dunnow about being bogged, that has never happened to my Patrol in 290,000km ... BUT today as I drove over the kerb into the local servo to put in a little petrol to get me to the dump, the bloody thing just shut down without warning. What a dog without power steering or breaks.
When I finally got to talk to the RACQ Mechanic on a roadside assistance call, he asked me if I could hear the fuel pump when I tried to start it.
" Hang on I'll try"
and the bloody thing started & ran like a sewing machine, as usual, for the next few hrs around the 'burbs'.
Buggar!!!
What was it that caused the shut down? Hate for it to happen way out west with the van hooked up, or even going up a range somewhere!!
Given that it was instantaneous without any warning I reckon it was an ignition fault. (I had shaken a few ignition connections after the stoppage).
So .. I'll spend a few days checking all the relevant electricals & throw in a new fuel filter, just in case.
Sorry to deviate from the main thread, but that's just the way I am. Too old to change.
BTW my 4X4 has a limited slip rear diff but no lockers.

An AWD is not a 4wd when spinning out on one wheel can remove the drive from the other three wheels.
My Land Rover is AWD when driven in it's normal configuration with the center diff open, as are I believe some of the Land cruisers.
However I have the the ability to lock the center diff when going off road turning it into a 4wd ( using the term loosely )
Without diff lockers It would still only have to spin one wheel on each axle to lose drive to the other two Wheels. Fortunately this never happens in a Land Rover.

Hi Bulldozer, My understanding of it is that the All Wheel Drive came into vogue when some sophisticated cars came out to be able to handle slippery conditions eg in Europe. There was a Lancer that was AWD (my brother-in-law used one as a rally car) - they had a "slippery" clutch that brought the axle into play when there was slippage detected. He ended up at our place on a rally with no-wheel drive & had to "modify" the clutch to drive on the rear wheels only.
Soft 4WDs came out a few years ago - the Subaru (Leone, Outback, Forester) was the best of the bunch for quite some time - giving drive to the front wheels with a 1:1 & a lower ratio when required. Then others appeared on the market - X-Trail, RAV, etc. I saw a friend's X-Trail stop at a dirt ridge - we called her up to engage 4WD & the car went over the ridge easily but lifted one wheel due to the limited wheel travel.
I would suggest that 4WD (or 4X4) points to the more robust vehicle eg Nissan Patrols, Land Cruisers, Land Rovers, Range Rovers, Pajeros, Pathfinders, Jeeps - the sky is the limit these days electronic whizz-bangs with Isuzus, Navaras, Everests, etc.
AWD had its beginnings in the early 1970s, upmarket cars were being fitted with braking control. Basically controlling each wheel's braking so they were rotating at roughly the same speed and also preventing them from locking. Come micro-processors and 20 years ago the Jaguar model X had all wheel drive. Then it was exported to be off-road targeted vehicles.
60 years ago I was driving Jeeps and Landrovers, but seldom did we lock the front wheels, so they were being driven as rear wheel drive vehicles most of the time.
The important thing is not whether it fits the romantic idea of four wheel drive but whether it handles all the expected conditions.
I drive a 4x4 vehicle and selected 4H drive mode when I took delivery of it in September and have never changed it since.
It amazes me that people have their knickers in a knot over this.
