How in the world do i get new transfer case, and rear dif (AWD) oil into the filling point????

is there a special funnel or pump that is required as there is no way of pouring it in.

Can anyone point me in the right direction??

Thanks

Yeah theres a pump/ bottle you can get from Autobarn etc, might be called a Tom Thumb; its got a hose with a hooked end to get into these spots

Long time ago in the UK, gearbox / diff oild from Castrol came in a squeezy pack with a long plastic tube.
Stuff tube in fill hole, squeeze until oil has puched up the tube into the gearbox.

N.B. Cold day - then warm the oil up first in hot water.
