Centre diff is locked - not front or rear.

As per the above post, the difflock is for the centre diff. The same as RRC, Disco I and II and all other Defenders.

Thanks for the info

Just so it is clear (and simple), essentially all permanent 4wd vehicles have 3 differentials. The front and rear diffs that allow the left and right wheels to turn at different speeds, and a centre differential between the front and rear drive shafts that allows for the front wheels to turn at a differnt speed to the rear wheels. The diff lock on a Defender, as earlier post have said, is on the centre diff. When locked this ensures power to both front and rear wheels. Front and rear diff locks for a Defender are only available after market. It is often argued that you don't need front an rear diff locks if you have a system such as traction control where the brakes are automatically applied to a spinning wheel (a bit like ABS breaks) to ensure that the non spinning wheel recieves some power. With a 'normal' (non-locked) diff, all the power goes to the spinning wheel.

Let say a car with TC and CDL

Scenario1:
cdl is not locked and one wheel is off on the air. Where the power will go to?

[KarlB]

The power should go to the three wheels that are on the ground.

Not quite immediately to the ground wheels, Karl, without the centre diff locked and with no traction control, power will go to the airborne wheel. ETC will then apply brake to the spinning airborne wheel and then the power should go to the three wheels with traction.

Yep that is the correct answer, old mate must be little confused now

I am just trying to keep this simple as that seemed like what was necessary. The delay is much nearer to a second than a minute.

Hi...2014 and I'm considering having elockers fitted to both front and back, as suggested by Opposite Lock South Sydney. The more research I do the more confusing...any advice please?

Rob, the big question is why? What or where are you going to use your new vehicle for to make it worthwhile?

Have you taken it offroad yet, and found it inadequate?

Lol....I have and been well impressed, but I wanna take it on some "explority" trips...and planning on doing Cape York and Simpson next year.

Then there's your answer.

Have a read through some of the many trip reports on Cape York and the Simpson. See how many you can find that say "if only I'd had a diff-locker".

Also, given your vehicle is pretty new, I would counsel caution at making changes that may give you warranty issues with Land Rover.

Scratch the part about warranty in my post above. I had read your post that you had a 2014 Deefer, though it's now clear where you have asked the same in two other threads that you have a 2009.
