Going to be changing the oil in the rear axle/diff of a 2013 XC90 D5.
This video seems to explain how to do it pretty well:
But I am pretty sure I need to remove a certain amount of oil once I've filled it so it comes out of the drain hole, but I cannot find this procedure in VIDA.
PS I will be doing a mini flush by putting new oil in the diff, swirling it around so it mixes with any old oil I couldn't remove and then repeating this process until the oil comes out clean.
Does anyone know how much needs to be extracted once it's filled up?
