Thread: Discovery 4 2013 diff lock.

Nup! No need to. It reacts faster than you can...

And it does staged locking... Dependant upon the surface.

Don't think of older 4wdrives...

You'll go wrong...

It's a different beast...

Gordon from GOE (search this site) does a great course to help understand what is a totally different system.

What you think you know may not be what you need to know....

What Tombie said.

When I moved from a D2 to a D3, it took me ages to come to terms with it. It is different to a conventional 4wd, but once you can understand what its doing and accept it, you'll love it. The Terrain Response really is a very clever system and there is no need to modify either the suspension or the drivetrain.

Cheers,

Exactly,i have had the D4 for 18 months now and i still have not got it sorted.
It is a completely different animal than what you have probably been used to.

GOE also has a good book which is very helpful.

Thanks for the info. I will be sure to check out the book from GEO. I was testing the D4 in some very soft sand to see if I could get bogged in normal mode then get out in the sand mode. Of course I was to bogged to get out & needed a push. Without taking to much notice just driving through the soft stuff it didn't seem to ever engage. It may not have needed to as it was doing it pretty easy though.

I doubt you'd feel any difference between locked and unlocked. The diffs lock and unlock gradually - its not just on or off, and they are doing it all the time in response to how much traction there is. The TR setting controls how aggressively this happens.

I've never been able to feel the diffs locking or unlocking in either my D3 or D4. I now have the 4x4 info screen in the D4 and this is the only way I can tell which diff is locked - its all so seemless.

Interestingly I have the rear diff as well and it often locks up before the centre diff, depending TR setting and terrain. You wouldn't expect this if you apply conventional thinking to it.
