You can use vacuum line if you want but fuel line or transmission line will get you better longevity.

I just finished rebuilding both axles and I used some 5/16" fuel line. It's reinforced rubber, what else do you need out of a breather hose?

Excuse my ignorance but I had no idea what that hose was for on my 84. Being a breather hose are you suppose to uncap it when wheeling off road.

It shouldn't be plugged. They should have vent caps in them. They don't need to be removed.

Thanks, I'll look at it more closely, maybe it is not a cap but vent.

My vent tube is broke off right at the axel housing. Does anybody know where you can get that part that actually fits into the top of the axel housing. Is that part threaded in?

It's probably pressed in. If you wanted to take the axle apart so you could clean it you could thread it

It's not threaded in. The fitting has these ridges in it than make it almost like a pressed fit. I don't even mess with these fittings anymore. I'd rather tap the hole (it's already the right diameter) for a 1/8" NPT fitting and thread in a hose barb that you know won't pop out.

Good Idea, thanks!

Pirate40-I replaced the axle breather hose on mine today. I'm bored to tears so I figured I'd post pics of the whole shootin match (not that anyone needs them)



I loaded up the 1/8" NPT tap with grease to catch the metal shavings and keep them out of the diff.


I'd use a bigger barbed end next time, but this is all my hardware store had:
