Outer Limits 4x4 Board

Does anyone have a how-to on how to change out the Uni in the front shaft of my 40?

Ive got the new unis, done a bit of googling and found some dude who changes them out in 7mins flat but I dont think its the same type (his have circlips but mine dont)

any help is appreciated... front shaft is out and waiting to go.

thanks!

Does this help?
