Drive shaft on Nisson

It sounds like I have a worn drive shaft cv joint on my old Sunny Nissan 1300cc 1988, as I go round a rounder bout turning to my right I get this clicking sound.

I would like to know if it is the near side or the off side that is worn if possible.

Can you tell as it only happens when I turn to my right.

Plus easy is it to change one my self?
