I've got a Sierra diff, and need to refill it with oil, Does anyone know the amount of oil you are supposed to put in? As there is no way of telling when you've poured enough, is there??. Also what type is normally used?

Cheers,

Mark

There is a filler plug,when it starts to over flow its full........I think !

If its an lsd you need to put in 1 litre.

According to haynes...

4x4 1.0 litres
Non 4x4 0.9 litres

Which presumably can be read as:

LSD 1.0 litres
Non LSD 0.9 litres.

ep90 should be ok thats what i put in mine.
take out the drain plug fill it up till it starts to come out of the hole ur filling it from .
thats it

i used ep 90 too.

the official line is 10mm below the filler plug iirc, but i'll be buggered if i know why they didn't put the filler plug 10mm lower. it's 25mm below ont the p100

take direction from those above. i'm sure it can't harm.

As already stated fill until oil runs out of filler hole , use EP90 for non LSD diffs but not sure about LSD diff may be different oil for them ?
