1998 Renault Espace how to change a c.v joint for espace 98

hi ya,recently broght a cheap renault espace on the understanding that it needed a bit of tlc,i can hear a clicking when turning left or right but the noise is coming from the right hand side whilst driving slowly, ive been told its the c.v joint,if its an easy-ish job then i will give it a go myself rather than go to any expensive dealer,but as im not sure exactly how hard or easy it is im hoping that one of you guys/gals could help me out please,what a great forum this is to,had real difficulty finding a workshop manual for the espace and resorted to the internet, which im now glad i did as i found this forum,any help will be really appreciated,many thanks.
