Thread: Rear e-diff retrofit to MY12 4.4 TDV8

At one stage I had hoped that the E-diff could be retro fitted to the earlier TD6. Activated by a simple on/ off switch . But then from the way I believe the factory E- diff works this probable not possible. Will be following your instelation with interest

If you want an electronic rear diff lock, look at Harrop/Eaton E-Lockers - see if they make one for the earlier L322s?

Edit- after having a think about it, I am sure someone could come up with an Arduino board to run the OE diff motor - whether it is a worthwhile exercise or not is another question.

For earlier models, I expected that with the different diffs fitted over the model run that the rear drive-shafts and cross-member would be different but not so, as the part numbers are unchanged. The tail-shafts are different but might still bolt-up to the flange. Obviously the diff ratio would have to match the front - 4.2SC e-diffs are readily available but their ratio could easily be different so might have to also fit the 4.2SC front diff. Otherwise wires would be needed to operate the brake solenoid, wires for the motor (expected to need to be reversible), power, earth and logic to interpret the hall-effect limit switches with the control module powered with the ignition. No need IMO for temp sensors to be working for simple engaged/disengaged operation.

sorry I'm not down your way so you can take a peek at my e-diff...I will have to find a reason for a long drive to visit!

This is what I bought. It will need a good clean to get through customs.

The way my lane is shaping-up it may not come quickly enough, having to give the throttle a good jab at one spot to avoid slipping off into the gutter.

Bit off topic but I was going to give you a shout last week Graeme, I drove my RR from Sydney to Adelaide on Wednesday and back again on Saturday and went thru Wagga ? Man it was so green out there.....all the way across the plain, it was like someone's front lawn! Had I a little more time, I would have dropped in......I did wave as I went thru Wagga and then when I saw some black faced sheep out on the plain. Are they Suffolks?

no wonder they weigh so much,,
I hope you have a mate to help lift that Graeme!

Solid black face and feet are most likely Suffolk whereas slightly mottled faces could be South Suffolk or a Suffolk cross. The black feet better handle wet conditions on flat country. Its been a very wet winter in this part of the country but is often very green in late winter anyway.

I was in Wagga Wed morning and nearby twice in the evening but your arms would need to be long to be seen from home 40K to the north, just off the Narrandera/Coolamon/Junee/Gundagai route. Dropping by would have been a good test of your tyres in deep mud but we took the van for a run Thurs-Sat so may not have been home anyway.

Pedro, I will be using a trolley jack - it reportedly weights 60 kg! But keep it quiet that I intend to ask son Justin with the D4 to help.

The diff and RDCU are on their way - hopefully they don't get lost en-route from St Peterburg.
