Thread: Discovery 3 e-diff

I have one in the D3 and have seen the picture of the front and rear diffs pop up between the Tacho/Speedo when it cuts in while crawling in rocky conditions and a wheel lifts off into the air.
Vehicle certainly does progress easily in those precarious situations when it appears as it has stopped momentarily when rock climbing before it has cut in, but I have not driven a D3 without it so would not tell how easily a non fitted D3 would get up.
I think there is a clip on YouTube showing the difference between vehicles getting up a hill. The e-diff did get further but there was not much in it, whether it is worth the extra money would be an individual decision.
If you take the vehicle places that you do not mind dents from rock climbing, like Mitchell Plateau etc, then the extra ability may be worth it IMHO. If you don't get into those predicaments, I wouldn't bother.
I like it and would order another personally, if it saves me using the winch and staying in the drivers seat (air-con), it is worth it to me.

There is a very good writeup on DISCO3.CO.UK on converting a standard vehicle to run the e-Diff.

I just wanted to update my response as there was debate on the locking diff. I have confirmed that the e-diff is a true locking diff.

It is either engaged, or not engaged. when it is engaged, it is a true locker. The clutch plates in the differential are designed to minimize damage to the axle and prevent damage particularly during engaging and disengaging. It is theoretically possible for slip to happen, but not when fully engaged, by design, the clutch plates will never need replacement.

Presently there is an e-diff ready differential, which can be fitted to a non locking vehicle. You can later add the bit of kit to make it operational. The e-diff ready differential is heavier duty than then non-locking differential, and will be quieter, smoother and last much longer.

Maybe someone needs to tell the guys in LandRover...

ISTR that the last time we spoke about this the answer came back that it isn't... but due to the nature of the beast, it behaves like it does.

I'll ask the question again & see if I can get the ear of one of the techie guys.

I can't speak on this for sure but I just got a new rear diff, it would seem that the old e-diff will not allow the Actuator to engage and align itself. The reason would apprear to be that the clutches will not allow the actuator to engage. It is either that this is the reason or that something else is not moving or willing to move to allow the alignment. Techs best guess is that the clutch plates are frozen or that the flywheel is.

The diff had been overheated and the following day, after startup the traction reduced warning came on.

Just what i know.

Is the e-diff ready differential a normal e-diff with some parts missing, implying that the e-diff is stronger than the standard open diff?
