Alright matey, they aren't too bad if you have done any other vehicle's CV boot. The real pain is getting the bottom ball joint away from the main arm, you need a ball joint splitter ideally.
Undo the centre hub nut, with the nut still on the threads so the nut is now flush with the end of the drive shaft, use a hammer to knock the drive shaft out of the splined socket, once this is done you can then move the drive shaft away from the main arm and take the split boot off the shaft. To remove the cv joint you need a pair of long nose pliers to take the surclip out from inside the joint, once the clip is out you can then take the joint away, clean the joint with a rag and take any grit or metal out, regrease with the grease you should get supplied with in the boot kit, use all the grease and place the boot onto the shaft and re place the cv joint and clip, zip tie up the boot as much as poss then re insert the shaft into the splines socket as much as poss, tighten the shaft nut. After this put the bottom ball joint back into the bottom of the arm, knock it up with a hammer to ensure its sat correctly and tighten the nut up, replace the split pin with a new one ideally but if you dont have any you should be able to use the old one. Tighten the centre hub nut up to the correct torque setting and replace wheel, jobs a goodun
