My old 5000T had about 115K miles when I sold it, and I never changed the
CVs.  My urQ has about 95-100K miles with the original CVs.  I wonder
whether it is necessary to regrease them.  I do get boots changed ASAP if
they get torn, and every chance I get, I look for the telltale line of
grease above the boots to see if one has failed.
