From my experience, its pretty straightforward albeit with limited access to do the job but you need to be aware of a few things
1.) I've never actually seen a torque figure for the diff flange nut, so ended up marking up the nut and working out the torque setting. Turned out it was something in the region of 146 ft lb, I think. There's a crush spacer used to set the crown wheel and pinion mesh, so this figure is crucial!
2.) There's 3 types of oil seal so make sure you get the right one, from memory, one at 6 quid, one at 12 quid and one at 40 quid!
3.) Its very unlikely the old seal will come out as one! Be prepared to take it out in bits!
4.) Finally, check the breather hole on the rear axle tube, its a small 3mm hole which easily gets filled up with muck and causes the axle to pressurise
