did mine last weekend, in about 20 minutes (did have a ramp though)
If its the outer YOU DO NOT NEED TO REMOVE THE DRIVESHAFT;
1. with the car still on the floor take the centre cap off the wheel and using a 32mm socket break the driveshaft bolt (i.e undo it a bit)
2. get the car off the ground, wheel off, and take the driveshaft nut off.
3. undo the 3 bolts holding the bottom ball joint on, slide the hub towards you and you should have room to get the driveshaft out of the hub.
4. You can now pull the old cv boot back away from the joint (if its split anyway just fold it back)
5, you then need to drift the cv off the driveshaft, soft faced copper mallet is best but if its stubborn, just give it some welly, it will split eventually.
6, replace boot, remembering to pack with grease,
7. refitting is a reverse of the removal as they say!!! oh and dont forget to put the new plastic washer & convex washer on too.
