Wes, it sounds to me like all of these are pretty well gone. I don't
think it's worth the time and trouble to try and salvage marginal CV''s.
Being where they are in the drive train and the kinds of loads imposed
on them,CV's ought to be in tip top condition or discarded for new ones,
IMHO.
Good luck,
John Rodgers
