Changing the Differential Fluid

[Kiefffff]

Are the diff drain plug’s magnetic to help trap the fine metallic material in the oil?

Can't speak for the drain plug as not touched it but the fill plug certainly has a strong magnet. Saved me dropping it once. Presume both are the same.

I just changed mine using Titan 80w90. The front had 2.1L and the rear about 2.05L. I filled both with 2.1L. The oil looked pretty clean (only have less than 5000 miles).

Are the diff fill and drain plugs multi-use with no crush washer?

They have an o ring

Are any of the diff plug parts one time use?

Are any of the diff plug parts one time use?

After noticing the front seal leaking I've topped up ours 5 times in the last 3 months and never changed or put a new seal in. About 400ml roughly to date, (circa 2200 miles).

Ineos we're happy with this following reporting the fault, I made them aware it was going in for a service in the next couple of months.

I've never done changed diff fluid before so I am going to put my pride in the backseat and just ask. Are these these the drain/fill ports?

From a process standpoint, my understanding is that this is pretty simple.

1) Start with a warm axle
2) Remove fill plug
3) Remove drain plug & drain
4) Replace drain plug; torque to 31Nm
5) Fill with SAE 80w90; 2.1L for both front and back
6) Replace fill plug; toque to 31Nm

Am I missing anything?

What is the Tool Type and Size for the Drain/Fill Plugs?

12mm hex socket

Thanks.
Just to summarize it and a couple more questions:
- 12mm Hex Socket for Drain/Fill Plugs
- 80W-90 Oil
- Which Oil is better or recommended? Mobile Mobilube HD Plus 80W-90 recommended oil (no SAE)? or, Lucas SAE 80W-90 HD High Performance?
- Clean the Plugs and confirm Oil level before wrapping it up
- No need for any new O-rings? Are there any crushed washers as part of the Plugs? (Cannot find any Part Number, if any)

Well you have them in the right order anyway.
Always remove the fill plug first, not the drain plug.

There's been a few people who have drained the diff and then had a hell of a time trying to remove the fill plug.
Or snapped it off using a rattle gun.

Not in a Grenadier yet that I am aware of.

I ordered new plugs with O-rings from the dealer, they don't sell just the O-ring.

Can you share the Part Number?
Also, is there really a need to change the O-Rings/Plug with only 5000 miles ?

I removed the Drain Plug to check the oil level and the O-Rings looked good.

I don’t have the p/n. I called Red Nolan and Angela mentioned they only carry the complete drain plugs so I ordered two of them and had them shipped. They are silver color vs the factory black head ones.
