I would have a think about putting that in the tfr case - diff probably OK but the tfr case is special and as far as I am aware the specified oil is only available from Landrover.

Your local Castrol distributor should have it.

I've always found that diffs with friction plates need some sort of friction modifier rather than straight gear oil. I'm pleased that the front diff on my tractor only needs a tube of a specific additive with normal EP gear oil rather than a manufacturer's specific oil.

looking for some info from oil knowledgeable persons
Have to change boots on front shafts and will top up diff oil with recommended oil, BUT what is recommended grease for half shafts?
Will likely get a couple of sachets with boot kit, but in case I don't get enough; molybdenum disulphide grease ??, same as most other CV's ?

Thanks Unseenone, have filed that list away.
Still not able to get a definite on what grease goes into the CV's.
I'm thinking molybdenum disulphide, but cannot see anything specific in the manual.Seems to work for everything else with a CV joint.

I can't imagine it is far different from what other MFR use. I would think that what comes with should be sufficient. Here you will see a product advertised for CV Joint Grease, it's only 3% Molybdenum Disulfide

I have had Penrite in both riffs for 50k, no problem so far. Use their engine oil and now coolant as well
