Hmm, remove axle and transfer components, I'd suggest. Actually all joking aside - it's pretty much that. Getting the axle off isn't hard really. Top and bottom arms, brake line, prop handbrake cable etc. Shockers and springs. You just need to find a way to get the chassis up. Don't the arms with the wheels on the ground and the weight still on it. The rear axle will roll away! Worth leaving wheels on though as it's easier to move about although you may have to jack the body up quite high.
Drain the oil first in situ perhaps.
You got an axle from Milners? Really?

Oh yeah! Just had a look. Well done you. I think that was closing down stock from a Toyota dealer. Nice find.
