CV's Worn?

[Mike Sylvester]

IME, clicking of the CV indicates wear in the joint and application of
additional grease is a waste of time.  If it were the case that the grease
dried up causing the joint to wear out, adding more grease does not fix the
grooves in the race.   If you take the joint apart you can visually see of
it is worn.  You will see wear grooves or pits in the outer race. It may
extend the life of the joint, however there will always be the possibility
that one of the wear grooves can catch a ball just right and brake the inner
race.  I'm sure someone ( read as Bernie) will relate how they have
re-greased a clicking cv and ran it for another 100k, but it doesn't seem
worth it to me.
