to check it remove the 13mm bung from the side of the diff not sure if its os or ns as vaux have used both, but dont fill it from here fill it from the top of the gearbox throught the 17mm breather in the selector housing. 
 
To change it you will have to remove the pan below the diff as there is no drain plug and then refit it with a new gasket.  
Then refill it through the aforementioned bung until it runs out of the level plug. 
 
Oh and use EP80/90 gear oil
