Jeep JK Wrangler Axle Breather Hose Extension

October 12th, 2009 | Category: Jeep JK Write-Ups, Steering & Suspension
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, you will find that 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.The write-up below will show you how to extend your axle breather hose in minutes and for dirt cheap.

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 JK Wrangler and pull the breather hose off of your axle.
5. Insert the opposite end of your double male connector into your Jeep JK Wrangler’s breather hose. 6. Loosely zip tie your Jeep JK Wrangler’s breather hose to the cross member above your rear axle as shown. 7. Plug your newly extended breather hose on to your Jeep JK Wrangler’s axle.
And there you have it. 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.Please let me know if you have any questions.

    Thanks for the write-up. In addition, when I did mine I routed the longer hose into the body behind the tail light.. I wanted some extra protection from water getting inside

    Has anyone heard anything about having to extend front dif or transfer case breathers?
