[30psi]

Its about 1.3 litres for the diff and probably about 3 for the box

[JackieFan]

Just fill the diff up so that it's level with the bottom of the fill plug hole. 1 liter bottles is probably the smallest amount you can buy it in anyway. I can't remember how much we had to put in the box but 3 liters won't steer you wrong.... if you can get the drain pulg out that is
