How to change the prop-shaft universal joint on MK5 Transit 1997 Smiley?

I am about to attempt changing the 'UJ' on my transit van, it does not have the normal circlips holding the 'UJ' caps in place. Does it need specialised equipment to fit new joint, or can it be done on the workbench?

Although I've changed numerous circlip types, this is the first 'non-circlip' I am about to attempt.
