Thats an option alright.id say bring back the cv boot mate and get a univesal one they stretch over the joint no problem there only €8.50 then u cut it to size
i would use a rubber mallet to be on the safe side as a hammer could damage the cv joint
yeah it needs to go back on futher the little circlip is more than likely preventing it from goin on the rest of the way. I used a flat head screwdriver to push the circlip into the groove so it can go on the rest of the way hope this helps
