    Rear diff (non locking) confusion

    Is the rear diff capacity a measured amount or fill to a thin line starts to drain out?

    It’s a non locking diff, and drained out 800ml

    Fill to spill (as per the JLR instructions) meant I’ve put about 1.3 litres in.

    Have I don’t right, or should I have put 800ml back in and called it a day?

    This might help. Taken from Workshop manual for D5

    As you can see... it is "fill till overflow".

    Thanks for the link, that’s the one I used

    If I filled it to the drain level it’s 1.3 litres

    I drained out 800ml

    Every oil guide illustrates a wet refill capacity of 8.2-8.5 litres, hence my confusion!

    8.2L for the rear diff???!!!???

    I think you are confusing th engine oil quantity with the diff oil quantity.

    I have done all the services in my D5 according to the LR service manual.

    Engine oil is normally about 7L (tdv6)

    Transfer box a bit over 1L
    Front diff a bit less than 1L
    Rear diff(open) approx 1L

    These values are also on the Liquimoly site

    I don't know where you got the idea that the rear diff takes 7-8 litres!!
