Got my new front diff today and also had the oil replaced of the rear diff. My local LR dealer told me that they switched from the by LR recommended oil to a different one and since then they have a lot less problems with diffs failing/leaking (like mine). The oil that they put in is Castrol SAF-XJ 75W140 API GL5. Not sure if it's any better but thought I would share with you guys. They said that they use it in the Range and Defender and have also quite good results on Discos.

Thank you so much for the time and effort you have put in to posting this. I have just changed my diff oils, transfer box oil and fuel filter (as well as the engine oil and filters) and your pics were invaluable.

It is quite important to point out, as I did not see it here anywhere. The rear "open" and "e-diff" oil quantities are not the same. The e-diff takes more oil. So if you are using the 1.1 figure with an e-diff you are short. It should be 1.6. These are refill quantities.
Unit Capacity
'Open' differential 1.1 litres (1.9 pints) (1.15 US quarts)
Electronic torque managed (ETM) differential 1.5 litres (2.6 pints) (1.5 US quarts)
You will find some pictures of disassembled diffs in my gallery.

Does the E diff use the same oil?
I believe it may be different to the standard diff.

I'm looking to do this job today and had a look on the halfords website. They do this stuff...it's universal rather than longlife...is it the same thing in a different bottle?

Thanks chaps - I've just gone with the LR oil as it seems impossible to get hold of the castrol stuff at short notice. Are the capacities the same for a 2.7 Range Rover Sport?

Job done. I got 300ml out of the front dif and filled it with 610ml. The fluid was dark brown with a couple of mucky bits.
The rear diff was a bit more interesting. I got approx 1.1l out and put approx 1.15 back in. Does this sound about right?
The rear diff oil was much darker when it came out and it had a silvery shine to it A lot more crud came out with the oil but strangely the oil plug didn't look as bad as the one in the pics in the first thread.
I had to use a syringe and windscreen washer hose to squirt the oil into the rear diff as I couldn't get the bottle at any sort of angle to pour the oil in.
Thanks for the 'how to'

Thanks so much for this post, this was the sort of job I thought was beyond me but did yesterday and was very easily.
I used a Draper Oil Suction Gun (lots for sale on ebay) and took the rear wheel off fpr better access.
The only thing I ever worry about is working under a 3 ton car only supported by dodgy suspension and axel stands (but thats just me being a whimp I guesss!)

Just done all my drive train oils today and used your post for Allen key sizes and oil quantities
The car is on 72k now and this is the first time its been done and all was straight forward to do i just had to remember which to add TSL to and how much to add along with my boss coming over and asking me about the brakes on his car which he was changing,what he really meant was come and have a look at this a minute i guess you cant do enough for a good boss and it is his workshop
Thought i would add some pics of the old oil and diff drain plugs so peeps can compare,the gearbox and transfer box plugs were clean and are not magnetic like the diff plugs.
Front diff
Front diff drain plug
Rear diff oil
Clean drain plug
Rear diff drain plug
Manual gearbox oil,the transfer box oil look the same
This is the pump i used worked perfectly and got in all areas easily and because of the bent metal spout it hook in the fill hole so you could pump away without it falling out.
I was surprised at the state of the oils because when i checked them on the last service they looked clean almost like new when dripping of the end of a cable tie,but as you can see there not so i wouldn't go by that.Wanted D4s non runners pm for competitive price.

I am planning on changing my fuel filter and was wondering about the merits of bothering with OEM filters which seem to be very pricey compared with aftermarket alternatives.
Is it worth paying the extra or is it one of those items where it's not going to matter. I must admit given the price difference I am tempted by the notion that it won't matter at all.
Cheapest genuine I have found is about £50 (not asked TLO yet), cheapest aftermarket is £10.
