    Jeep JK Wrangler Axle Breather Hose Extension

    In addition to installing things like longer sway bar links and brake line extension brackets, when you lift your Jeep JK Wrangler to a height of 3″ or more, it’s a good idea to extend your rear axle breather hose as well. If you don’t, you may find that the hose will get pulled off the axle when flexing out on the trail. While this is not that big of a deal in and of itself, the hose being separated will allow water dirt and debris to get inside your axle and that can cause big problems. Fortunately, extending your axle breather hose is cheap and easy to do and can be done in minutes by following this write-up.

    What you will need
    • 12″ Length of 1/4″ or 5/16″ Fuel Line
    • Universal Emission Vaccum
    Double Male Hose Connector
    • Zip Tie

    Instructions
    1. Here’s a shot of what you will need in order to extend your axle breather hose. As you can see, I chose to use a universal vaccum double male hose connector and 1/4″ fuel line for this mod.


    2. Determine the size you need the universal double male connector to be and cut off the excess with a pair of scissors or utility knife.


    3. Insert one end of your double male connector into your fuel line hose.


    4. Climb under your Jeep and pull the breather hose off the brass nipple on your axle.


    5. Insert the opposite end of your double male connector into your Jeep's breather hose.


    6. Loosely zip tie the breather hose to the cross member above your rear axle as shown.


    7. Plug your newly extended breather hose on to the brass nipple on your axle.


    And that's it, you're done. Your Jeep JK Wrangler’s axle breather hose has just been extended and you no longer have to worry about it pulling out when flexing on the trail.

    These are the kind of fixits that used to be a part of another forum but have been missing for a while.
    Thanks Eddie for your know-how and care.

    did mine a few months ago.


    Moved my breathers for my axles to higher ground. You guys that lifted may want to consider this as my front one got pulled down about 3 inches due to flexing. It was basically in the wheel well. Lots of damage if an axle sucks water.
    And just for extra measure I clamped the tube at the axle

    I also got tired of all the dirt and mud inside the tub behind the driver rear taillight. So I took expanding foam and sealed it.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
