What actually stops an e-diff retrofit?

[winaje]

Starting to think of some options, I noted a reco'ed e-diff on ebay for a bit over $1k. So I am wondering what actually stops the retrofit of an e-diff into a D3 that doesn't have one? From what I can see if you are committed enough you can retrofit anything...

I assume the diff has to be installed, electrical cabling fitted, then the ECU told that it's there. Is there anything else?

TIA

Will, there was someone on Disco3 that managed to do it. Have a search on there.

From what I recall, it was a lot more than just the diff and some cabling, but the rear axles, and other bits.

There is also the ARB airlocker option if you are keen.

Retrofitting the e-diff, as Sheerluck has said, is far more involved and expensive than just putting the diff in and connecting it up.

I understand the rear diffs in the v8 are a different ratio to the diff in a TDV6. That's something you might need to confirm if looking to buy.

It's a huge amount of work, which makes for a very costly retrofit. It adds comparatively little in terms of off-road performance in most 4x4 situations.

I think that most have decided that considering that it's a only a $1000 option when new, it's not really worth the effort in terms of added value.

That said, if your interested in the "hobby" aspect, then it could be interesting.

Sheerlucks project has been a great and interesting read. At the end though, he'll end up with a fantastic car very cheaply, depending how you cost out labour.

Definitely the case. Different part number. I know, because I nearly hit Buy-it-now on an eBay auction that was going cheap until I did the research.

You would need the whole diff including the stepper motor mounted on top as well as its ecu from a MY07+ D3.

We are actually working on a retrofit e-diff kit. This will allow %lock via switch in the cabin, and be separate from the vehicle system (not integrated).

It can be done, like the fellow in UK if you are willing to do the work and source the bits.

If you want the ARB, but need new gears (any std. ratio), bearings, crush sleeve etc. to fit the air locker, I can supply that.

The ARB kit is for fitting on a non-locker diff, or the front. (two separate kits) and also require an additional compressor.

The locker can be fitted to a non-locker vehicle directly by removing the e-diff motor, and fitting a sealing plate in it's place (until our kit) is ready.

The rear half shafts are heavier duty on a locker fitted vehicle, but will work just fine as direct swap into the vehicle which has a non-locker half shafts. If you have to replace axle half shafts, you can always fit the heavier ones.

The D3/RRS diffs are the same ratio in a Petrol. TDV6 & RRS supercharge Petrol are the same ratio.

V6 Diesel engine - Manual transmission 3.07:1
V6 Diesel engine - Automatic transmission 3.54:1
V6 Petrol engine - Automatic transmission 3.73:1
V8 Petrol engine - Automatic transmission 3.73:1

So Unseenone, can you supply rebuild kits for any D3 / D4 RRS locking or standard diff?
Be a good alternative for anyone who is handy with the spanners.

I see you are in the states which may see shipping cost a bit though unfortunately,

Any idea on shipping costs to Aus?

Cheers Rich

Yes, Yes & Yes

Yes- Gearbox shops, or folks with Diff rebuild experience, who can take the time to do it right. Or import completed ones, and export ones that are shot.

I see you are in the states which may see shipping cost a bit though unfortunately.

I know, I buy quite a bit of stuff in Australia, and it's very costly for the smallest object. I am looking for resellers and shops to import a large enough shipment to do sea freight, way way cheaper. Great products, we manufacture our own gears, and components, bearings are OE. The companies of choice would be doing the marketing, and helping out the LR community. First they need to know the product exists.

Any idea on shipping costs to Aus? -
One at a time, it is not practical.

I believe we have some stock in Australia. I am looking for shops and resellers who can order larger quantity so it can be shipped sea freight.

You can drop me a PM and I'll provide you details and where to check for current stock there.
