Hey buddy, its pretty simple really. Depends if you want to take the shaft out or not, if you do remember to catch the gearbox oil that will come out of the box! Two people would be handy to do this, one holding the shaft while someone taps the CV joint off the shaft. We used a blunt chisel and lump hammer, just whack the CV joint, turn it slightly give it another whack and keep doing that so it comes off evenly and doesnt damage the splines. Then you will need to clamp the c clip back onto the shaft when refitting the CV. This is really fiddly and we used a water pump pliers and screw driver to get the C clip small enough to whack the CV back over it. Good luck
