Am i missing something Grease for life should be in the swivels and therefore they shouldnt need to be drained and thus only checked through the top plug (there should be a rear drain one)

As for the diff oil...i wonder

THey are supposed to be greased/sealed for "life". I was just mentioning the above in case of water contamination. The only plug is to fill in with one shot grease (#STC3435) which is about 350 cc.

Thanks Dgardle
one more question. In RSA Castrol only have the BOT 130M which is a GL4 (75W80)
- will this still be OK?

For interest I called LR parts who would not give the specification but told me I could only get the oil from them at a cost of ZAR 369 per liter as opposed to Castrol who charge it at ZAR 79 per liter.

BOT130M it's ok, is the predecessor of 328 (in Italy at least....) Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

I still am confused somewhat

On further investigation:

The TexacoEP-C 80W-90 (listed as diff oil in user manual) has very similar specs to the Castrol EPX 80W-90 API GL-5 as below:

Texaco
Density at 15'C 898kg/m^3
Viscosity 100'C 14.5
Viscosity 40'C 131
Brookfield Viscosity @-26'C 130,000
Pour Point -33

Castrol EPX
886
14.2
140.3
130,000
-30

BOT130M
873
15.1
76
3400
-54

Seems EPX has closer readings so won't be detrimental?

Anyways, I dropped the oil in both diffs. Front was very black with slight water emulsion and seemed a little greasy. Must check swivel housing levels tomorrow. Rear diff little brown but not nearly as bad as front.
I refilled with the EPX as above until someone advises me I made big mistake or not.
Cheers 4 now

I wanted to stick my finger down the filler hole and check the level.
If EP0 is fairly runny then it should leave a level of sorts that you could feel with a thin pinkie finger - or not?

no way to check with finger

Another thing to note, when I removed both filler plugs on the front and rear diffs and buffed the threads in the wire buff to remove the old thread sealant, I noticed both threads were stripped/ damaged.
Seems the filler socket/insert is welded into the diff housing which causes the thread to shrink. Normally one needs to run a tap through again after welding in such a thin socket. They must have then forced in the filler plug in the factory, damaging the threads. The drains were ok however.
Anyways, ran a thread file over them a little but not much to salvage.
I fitted a light layer of hydraulic thread sealer on the threads before refitting.
Amazing that this can be happening in the factory. I assume
