    Gearbox - 75w90 fully syn @ 2.75L
    Rear diff - 75w90 fully syn @ 1.9L

    Youll need the big 12 point spline socket to drain them both !!

    Filler plugs -

    Gearbox - 17 or 19mm sump plug key iirc
    Rear diff - 8 or 10 mm allen key iirc

    Always make sure you can get to / undo / have the right size tool for the filler plug BEFORE you remove the drain ;)

    You dont need to remove the drivers wheel or passenger for that matter it can be accessed easily without removing the wheel as the filler plug is on the n/s on uk cars !!

    The fill plug for rear diff is on the drivers side on uk cars !!

    Aye those are far better.

    How about this, Motul Gear 300 75W-90 Racing gearbox and differential lubricant, for both box and diff?

    I can work my way around engine oil but the gl4/gl5 specs for gear oil need adhering to.

    cheers
