It will take about 5 hours or so. You need to remove the front suspension, or at least pop the lower ball joints and rod ends. Popping the ball joints will allow you to pull the drive shafts from the box on the left and IRD on the right. Don't actually pull on the shafts to remove them from the IRD/box though, they need to be levered out as there're retained by C clips. Drain both IRD and box oils, before pulling the drive shafts.
When the shafts are free I turn the struts so the shafts swing forward and support them by hanging with bungees. Don't over extend the shaft joints as the boots can split.
Then unbolt and remove the IRD from the support bracket on its right and unbolt the IRD from the box on its left.
Either clamp the IRD coolant hoses and remove from the IRD cooler, or drain the cooling system and remove the hoses.
Then support the engine from below with a trolley jack and a small block of wood to protect the sump. You actually need to place the jack to the far left of the sump and lift the engine slightly. This will remove the weight from the box mount, which then needs to be removed completely. Remove the battery and tray to gain access to the box mount, and remove the wiring to the starter. The starter then needs to be removed and the reverse lights switch needs unplugging.
From then on you should have the box clear of all ancillary components, so can it can start to be unbolted from the engine. The exhaust sometimes needs to be dropped, and sometimes not, it just depends on the space available to you.
Leave one top bell housing bolt fitted, until you're ready to remove the box. At this point I lower the jack supportung engine, which will allow the box to slide out under the chassis rail. Be prepared to take the weight of the box (about 35Kgs) and don't allow it to hang on the input shaft. I place a second trolley jack under the box, so I can withdraw it from the engine and wheel it out under the car.
