If you can get away with repacking and new boots on your exisitng axles then I would just do that.
Remove the wheel centercaps, crack the axle nut. I think it's a 30mm. The manual says to remove the ball joints, mark them so they go back into the original position. Remove the bolts on the axle flange and I think it should come out. I think it's also possible to get it out without removing the ball joints but it's easier to just remove them.
If they are clicking then just get rebuilt axles. If they just lost a little grease, I suggest new boots and regreasing the bearings. Your Bentley should have a section just for repacking CV joints. Also, you should get a new axle nut since it's a high torque item and it holds the wheel on!
