Differentials and transfer box oil change

Hello to all.
Finally got all the materials to change oil in the front and rear differentials as well as the transfer box.
Land Rover dealership in the south France are totally ridiculous with appointments and pricing.

Anyway, was waiting for the 500cl syringe and 14mm Allen key needed for the front diff to get started.

Since "The Beast" just reached 145000Km (90K miles?) was definitely time to get fresh oil in her.

Was surprised how straight forward and rewarding (fun) the job was. Hardest part was raising the beast enough to slide under to reach the diffs and transfer box.

Started with the Transfer box: obviously always undo the filler plug first before removing the drain plug. All you need here is a 8mm allen and a bit of force to crack them open.

The oil was definitely in need of changing. Since i had 2 litres of oil and only needed 1.5l i flushed the box with a couple squirts of fresh oil. On each diff and box drain I let the oil drip a good time until no drops appeared.

Replaced the copper washers on both plugs before filling with 1,5l of specified oil.

Next was the front differential, this requires the 14mm allen. Was aftraid it would be harder to reach the plugs but with an extension was a breeze. Very tight but not worrying. hardest part was removing under body protection. Again released the filler before removing the drain plug.

Oil was quite black and a very small amount of metal powder/paste coated the magnet on the drain plug. Nothing excessive.
Flushed again with a squirt of new oil then syringed about 750cl of oil after installing drain plug. Slight overflow on last centilitres.

Last did the rear diff. 8mm allen for filler plug and 3/8 socket for drain plug, again a bit tight but quite easy to reach. The oil was not as black as the other but was definitely in need of a change.

Squeezed 1.15cl of fresh oil and closed up the filler plug.

All in all took about 2 1/2 hours, mostly spent filing the 500cl syringe at proper levels and injecting the oil in the boxes. The syringe was quite slow and required multiple fills.
A fun afternoon job requiring only basic mechanical skills. Total cost less than €100, nearly a tenth of local LR dealer quote for the 3 changes.

Took the beast for a test drive and I did feel a nice difference, seemed quieter and smoother. Run through the whole range of gears high/low and felt wonderful.

The underside of your car looks very clean. The transfer box looks almost new.

Not really sure. I have a kit with several sizes since I also play with Vespa's and motorcycles.

I saw on YouTube If you gently heat up your old copper washers to red hot and let cool off they regain their softness and can be reused.

As long as they're not too flattened, annealing a copper washer will allow it to be reused. I've done it for decades and never had any issues. 2012 (L322) 4.4TDV8 Vogue SE, RSE, Fuji White over Arabica.

I am following this guide and so far so good for the transfer box and front diff. The rear diff is another story.

It was a bit of a pain figuring out which were the correct part numbers for the replacement drain/fill plugs. The transfer and front diff parts were correct.

Some posts indicated that the rear diff fill and drain were the same superceded part. I have got two 3/8th square plugs TYB500110 - does anybody know if this is correct? The current fill plug is a H8 as per this original post.

Additionally, there seems to be two drain plugs, one H8 and another the 3/8th square. I have seen other posts saying both drain and fill are H8 which is confusing. I assume I want to leave the H8 alone and drain with the square plug?

I have a locking ediff in case that makes a difference.

Here are some photos - hopefully somebody can ease my mind and confirm these are the correct plugs to remove and whether I have got the wrong replacement fill plug:

I'm about to do this project as well. My Autobiography is overdue. I just received the special Land Rover fluid for the eLSD (50$ per litre!).

Great to see another member in the Principality. I have a 2010 L320 SC at my flat in Fontvieille.
