I would think that, assuming it's the CV and nowt else that's bust, you will need to remove the calliper, then the disk/hub. Remove the stub axle (6 bolts), check that none of the threads are damaged when you do this, I had one strip the thread from the steering knuckle casting so I swapped it.
The stub axle supports the cv joint which should now slide out, along with the halfshaft.
Inspect the CV support bearing (solid bronze) for obvious damage, it should be a snug fit onto the new CV. There is also a bronze bush on the halfshaft and an oil seal in the back of the swivel, be careful not to damage it with the halfshaft (splines ets) as it involves removing the swivel globe to change it.
If the swivel oil seal (huge) on the back of the steering knuckle is leaking then this is the best time to change it, with the CV and halfshaft already out, unbolt the swivel from the axle (6 or 7 bi-hex14mm bolts, depending on year), take it to a bench and remove the 6 bolts holding the steel cover over the seal. There are 2 thicknesses of swivel seal, 8mm and 12mm IIRC and I think the 8mm is the later one but I couldn't tell you what year it changed, sorry.
Fill the swivel oil seal with MD grease before reassembly. As the book often says, by reversing removal procedure. With the swivel off the car and the seal removed you might also like to check the swivel preload, but if the steering is nice then don't bother.
