Lockers, Diffs and Drives.

Being a newbie to the LR world, I was wondering whether you could put me straight about the 4wd system. My S111 88" ('81) has freewheeling hubs. If I lock them and put the vehicle into 4wd by depressing the yellow knob, by my reckoning, I am in 4wd, high ratio. Are the diffs locked in any way, across the axles, or is it simply that both axles are now in drive, but the wheels won't necessarily all turn in a slippery situation? And if so, does one have to fit "lockers", as the Americans call them? Any info or link to an explanation would be very gratefully received.

Hi Chris
Yes you would be in 4wd high range with yellow knob down
Have a look at the thread above “what’s all them levers for”
This and when using the red knob ( which gives you low range) engages front and rear props but does not lock the diffs you can get kits if you wish to
It might stop you getting stuck on wet grass like @ciderman in the Deestone thread

What you describe is just that. 4WD in high ratio. Axle diff's are open.
Axle diff locks, limited slip diff's, and torque bias diff's are aftermarket items.
Have a look at Ashcroft transmissions web site.

Series work fine in most situations with the std open diffs. As there is no centre diff it is like have the centre diff locked on a modern 4x4 (which is why you should not drive in 4wd on grippy surfaces). The off road traction is provided by keepig all four wheels on the ground so its important to plan a route for that and keep the springs oiled and free.

That's again, useful. Thank you.
