the diff oil level should be checked when the car hasnt been driven for at least 6 hours otherwise the oil will be areated with small air bubbles and give a false reading
lever off the rubber bung and if anything flows out, let it, if theres water in the axle ( from driving thru water) everything will need to be drained out

otherwise use your finger as a dip stick, put it in and bend it down to check the level

if needed, fill it to the bottom of the hole

since the additives all wear out eventually, its not a bad idea to occasionally change the diff oil. sadly the bottom housing bolts arent drilled thru ( as they are on some earlier holdens) and so wont work as drain plugs, a syringe will be needed to suck the old oil out and to put the new oil in

diff oil no longer seems to have the old familiar hypoid smell, anyone know why?

also check the breather on top of one axle side as if this gets blocked with mud, all sorts of leaks and problems can result

5 spds have a threaded square plug, like a hex head but only 4 sides.

Undo this with the right tools, or you can stuff them up.!

To check the oil level is the same as the diff. Level with the bottom of the plug.

Oil should look similar to olive oil. Any discolouration, and should be replaced.

Gearbox oil will normaly last longer than the box itself.

Good Luck !:coolpimp:
