Crack off the hub nut, (30 mm or 32mm) before you jack the car up as these car be FT, remove the wheel, remove bottom ball joint nut, seperate bottom arm from ball joint (you may need a ball joint splitter as the tapper joint can be tight), now you should be able to pull the hub away at an angle and pull the drive shaft out of the hub, (these can sieze on the splines and may need wd40 and a tap with a copper hammer) if no soft faced hammer is availible or will not shift it put the nut back on before hitting it to protect the threads, so far all very easy.
Use a screwdriver or a hammer and blunt chisel to remove the drive shaft from the gear box you need a drainer to catch the gear box oil, and refit in reverse order, then repeat on the other side, then with the car level top up the gearbox oil
This should onl take about 1.5 housr per side depending on skill level and any siezed nuts/bolt you may come across
