Well the yoke should have a little "shoulder" so the u joint cap doesn't fly out. The strap really just prevents the ujoint from going over the little "shoulder" thing. I found this out because somehow when my ujoint blew up the little shoulder peice got torn out. I couldn't figure out why the caps kept flying out no matter how tight I torqued them.....When I finally did really this I put a washer between the ujoint and the strap and put a dab of JB weld on the end and haven't had trouble since. /forums/images/graemlins/peace.gif
