I don't know the figures, so am guessing, but if low miles put on since new grease and replaced CV, and not a lot more miles will be put on before Fall Overhaul, and boots are ok....

I have read that one can sneak in some lube under small end of boot using a needle of some kind. Some kind of attachment on a grease gun maybe? Archives will tell all on that one. As others do, I run my boots w/o that clamp on small end.

Recently had my drive shafts out. Trying hard to recall, but pretty sure inboard CV's showed grease drying out faster. Not completely gone, just dryer. Say after 30K miles. So if you don't pull the axles, make sure to add grease to inboards at very least.

Of course if you do pull them, I can't speak highly enough of flushing out the bolt heads with WD40 or some such cheap crap along with clawing out mung with a pic. Then take time to tap in the hex or star tool so it's seated well before turning each bolt.
