This is also Land Rover's advice. I've done a few training days before I got my license and they say reverse the last thing you did to remove lock. If you went forward and left then reverse left to get the lock out. Always make sure that the light is out before you set off on road.
I do serious off roading most weekends.
Yes you are wrong jon, Disco's, rangies and defenders have 4 wheel drive all the time, just that all 3 diffs (both axles & transfer box) are able to *work* so if 1 wheel spins, you loose drive to the other 3 wheels as all the diffs are still open & working. When you lock the *difflock* as has been explained previously, it only locks the transfer box diff, sending 50 /50 drive to both axles, if 1 wheel then looses traction, you still have 50% of the drive is still going to the other axle which keeps the vehicle going (the one with the spinning wheel has now lost drive due to the diff in the axle still being open) As previously explained as well, if you loose drive to a wheel on each axle even when difflock is in (ie. cross axled) then you loose drive, Full stop! as both diffs in each axle are still open and working.
The next step is to put *lockers* into the axle diffs, these then lock those diffs up as well and so that all wheels will drive no matter what.
I had a series 3 a long time ago, and if I remember, it basically drove both diffs, with the drive being used by the rear diff normally,with the front just spinning the drive shafts as they weren't coupled to drive the wheels unless you locked the hubs. high & low range worked on either setting. (but I will stand corrected, as it's a long time ago!)

that is free wheeling hubs ,but series dont have center diff as they use 2wd for road use (rear wheels) so front prop driven by transfer box prop still turns as front wheels are driven by road ,when you engage 4wd a dog locks front output to transfer box drive shaft that is already driving rear so both are physically locked togehter ,this give you the same 4wd as def.disco etc, free whel hubs are after fit device to stop wheels turning diff and prop while in 2wd thus supposedly taking some effort off pushing vehicle forward, so v8jon is correct
Even if you don't go off road reguarly, you need to put it into diff-lock at least one a month, and just go back and forth, and back to normal.
This is to make sure that the linkage is free to move, you don't want to find you can't engage it, (because the linkage is siezed), when you need it.

A good point well made ... I do this once a week when driving up a green lane.
What for? Aparently you don't need to

To keep the diff lock linkage in working order, not because I need diff lock.

Agreed. No car manufacturer adds 4 wheel drive in case you beak an axle :doh:
thats your opinion , but it just depends whether more landrovers break their front axles than do extreem offroading..... i probably drive off road more than a lot of owners do but ive never yet had to use the diff lock toget where i want to go, often with a trailer on the back. . but i have used it on road to drive home when a front cv joint broke
anyway have you no sense of humour?
i agree that it wasnt what vthe designer intended it for ... but et a life

Well I use it every day on my way home or I wouldn't be able to climb the mud banking into the woods. I've also driven 40 miles with no front prop because my axles snapped and bent it.
