Front Axle Breather Question Dana 30

Hello,

Can anyone show me a picture of how the front axle breather tube should be routed on a 1986 CJ7? Mine just goes up to the frame, and is just stuffed onto a hole in the frame. Lastly the breather cap in broken off.

Thanks,

Kevin C

Most of the time when I replace them, I run it as high up as I can and then loop it back down. Then again, I get into some pretty damaging things in the woods.

Thanks for your response. How and where do you run it? Do you attach to the fire wall, just ty-wrap it? do you have any pics? I want to do it correctly, and deffinatly want to keep it away from mud, and water.

It attaches directly up to the RHS radiator and secures at the top thereof i believe

As long as it's up high enough to keep water out there really isn't a wrong or right way to do it. From the factory they were routed up onto the grille shell and attached to one of the same bolts that the radiator uses.

I have been thinking about running my vent tubes inside under the dash.

I'm not sure I would do this. Unless you like the smell of the axle oil.

I thought about that too. The smell might get bad in summer

It might clash with our already gas cologne we are use to smelling like.

Mine has a strange...liquid wrench and oil smell...my wife hates it, maybe that's why I can't get her to ride in it, or touch me?

Even with my carb properly tuned per the Holley section on JunkyardGenius I get that cologne...adds to the experience I guess.

Axle Vent Tubing

Okay,

Quick question. Does anyone know what type of tubing that is for the differential ventilation? I want to replace both front and back (Dana 30 / 44). After 27 years mine is looking sort of old and ratty.

Regards,

Kevin C.
