Armed with the info I got from this forum - I went to Midas.
For the Diffs:
Caltex Thuban Gear Oil GL-5 80W-90 (6 x 500ml)
For the Transfercase:
Caltex Easyshift Transmission Oil GL-4 75W-90 (6 x 500ml)
It was the first time for me doing either of the jobs, but the oil changing on the axles went smooth. It took just under 2.8 Litre oil for both axles.
Then onto the Transfercase. The Filler bolt took me a while to undo. After a few hours and plenty of Penetrating Spray I got it out.
I drained the oil, cleaned the magnets and started to refill.
Now my question - I could only get 2 Liter of oil back in? The manual states that it should be able to take 2.8 Liter?
Is there a specific position the transfer should be in? Or is there something else I did wrong?

Unfortunately I did not measure the amount of oil that came out.
Please advice!
