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.

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?
Yes it is a good idea to extend all hoses on your Jeep if you plan on riding through water. If you go onto the JK Forum you will see plenty of write ups on how to do it.
