I came across this thread that pointed me at how to clock your CV joints.
 It basically involves ensuring that the wide/narrow parts of the CV do not
match.  The theory all seems very sane to me.

Have any of you heard of this before?

I read somewhere about people adjusting the small end of CV boots further
toward the centre of the axle to stop "clacking" - that sounds like perhaps
it could be a bad way of fixing an 'unclocked' axle.

Perhaps this accounts for a higher CV boot failure as well?  All seems
plausible.  Certainly better quality boots will last longer, but asking a
CV boot to hold the joint in alignment seems like the wrong part doing the
work.
