Thanks for all the responses on this.  Obviously this is a pervasive
concern & common experience.  The CV joint boots were replaced in 2003
either at the Honda dealer or a reputable garage.  Half-axles/CV
joints are original.  No clicking or thunking at all & boots are good
- no cracks at all.  The grease really is coming out of the ends of
the boots under the clamps.  I'm intrigued with the approach of just
replacing/tightening the clamps, at least as a 1st step.  Does that
require special equipment/tools?  Is that something I could do myself
or is it a 5 min job at the garage that they probably would not charge
much for?

Aftermarket shafts with insufficiently tightened boot bands. The shop can
replace the bands without removing the shafts from the vehicle. Should be a
quick and cheap fix.

The shafts may go a long time yet even with a lesser amount of grease in
the joints, so it's definitely worth a try before replacing the shafts.

96 EX Accord w 150k miles.  On right inner & outer & left inner cv
joints there is a grease leak from the ends of the boots.  Boots are
good & the boot clamps look ok.  Why/how is grease getting out?  No
typical bad cv joint symptoms yet.  Garage recommended new half axles
- apparently nobody changes just boots anymore because of the labor
costs.  Before I go that route I'll get a lot more miles out of these
- at least until they start clicking.   I've not heard of grease
leaking from good joints/boots.  It's the vertical sling out pattern
on the facing & backing surfaces & right where the boot/clamp there is
seepage.  Any ideas?
