Peugeot 407 2007 2.0 HDi CV Boot Replace

Hello.

During this weekend i shall replace one CV boot.
I have looked in Peugeot ServiceBox, but can not find for how to split the CV joint?
Is it an internal Lock-Ring like Audi A4?
Can you just hold the axle, so its not come out of the gearbox and tab with a rubber-hammer on the backside of the CV joint?
Maybe it self-explaining when i start, but i also want to know if must buy or borrow some special liners, or tools.

Thanks.
