usually with most vauxhalls -if you jack up car ,remove old cv boot and put full lock ,you can release cv clip andpull shaft out if it dosent clear then you can lever engine assy to allow shaft to drop out . if new boot is hard type plastic use proper boot clips, cable ties wont stay on for long![ you used to be able to get a spurious boot that was split and you glued it together may still be available]
