Yes!!
But what replacement shaft do you have???
The steps are:-
Cut the band only on cup..not both...
and remove the ballrace/joint from the green cup...
...this releases the outer / half shaft.
Clean out the existing green cup...and put copious grease in it
Insert ballrace/joint of half shaft into green cup..with boot still attached to new 1/2 shaft.
Use either an off the shelf metal band ( need banding tool too ) or a Zip tie..
...to secure boot to indent notch in green cup.
Re-assemble the rest..pour a cocktail !
Hope that helps
