Breather hose - very little of any thing comes out besides hot air and that’s why it’s there solely to keep the boot from ballooning.
Grease - if you’re not running “the good grease” then solve for that but after a year of track days just pull the boot back check the grease and add more if needed or remove and refresh.
The diff fluid is part of the heat equation. Metal conducts heat quite well so if your diff fluid is 250f then so is your axle grease plus whatever other heat is introduced to it or that it generated itself. You can install a greddy doff cover to reduce diff temps and as a byproduct less temp will be transferred into the cv.

Thanks for the reply rice_burner, my small brain couldn't get around the "all the grease will fly out the tube" thought.
Yes, first (Original OEM) axle lasted 2 years, around 100 days on track. Actually failed at Road Atlanta one day and I didn't have a spare and still ran the greaseless one at Barber the next day. Replaced that one with another spare OEM. It lasted until Sebring last month, total of about 18 months & 70 days on track. So I replaced it again with a "take-off" OEM out of a parts car...this one failed at my next event at Daytona this past weekend.
I have some Redline CV-2, new boots and clamps to repack the one I just took out...just wanted to be sure this should be a "fix", Thanks!
Love your build thread, we have a crew in Florida all with dedicated 86 track cars...just don't campaign them in any series currently.
