Do I understand that you are poking a hole (alibet a small one?) in the boots to inject grease in?  How large is the needle?  Do the boots have a noticable hole left over?

I was speculating earlier in the month about getting grease into my old but
sound CV boots. Well Sunday I was wasting some time in a small Canadian tire
store while my wife visited her aunt in the hospital.... and I found one
heck of a neat tool.... it's called a grease needle. Looks like a large size
needle with a grease fitting on the end. Well I bought a few tubes of CV
grease and injected grease into every boot I could find..... Here's the good
news....My CV's (all 8 on a Syncro) are much smoother, and make very little
road noise now..... Here's even more good news..... back on the transmission
are two boots, that cover the shift rod bushing. I have been having problems
finding 1st sometimes, the gear works find, just finding it is some what
vague.... well now... it's very clearly defined. I really filled those boots
up, so they expanded and covered the whole area they can cover (they had,
kind of, collapsed and some shift rod surface was exposed, I actually did it
3 times, each time adding more until they were full and until I got the best
response)......You ready?.... some more good news....the Tie rod ends & ball
joints, both got a few shots.... Now the whole front end seems a bit
smoother... I've always wondered why there were very few grease nipples on
the moving parts on this van????  Well now you can make your own on any
equipment that has a boot. You will be injecting clean grease without having
to open or disturb anything....One thing you do have to be careful of, these
needles are delicate, don't go ruff housing around with them, or you could
break it off in your joint....ooh that hurts just saying it :^)

Here's the facts;....
LubriMatic Grease injection needle,  code 11181
Lubrimatic Stant Corp. Dixion, IL 61021
Think it was $5.95CDN.... One of
the best lube tools I've ever found.
