Hi mate Briggie gave me a nudge, I have a bad memory so cannot say how much oil you need but it will be in the manuals section, do not jack it up as you will not drain it all, you cannot drain what is in the fluid flywheel anyway, there is enough space for most people to lay under and pull the drain plug, but do it hot after a run, all the crap will be in suspension and come out with the oil, not sure about the filter, LSD oil amount depends on the Diff if mounted from the front it takes lots more than if it is mounted from the rear, from the rear it only takes about 1.7 ltrs front takes around 3 but could be wrong, Rick
