I have heard the 80 guys talk endlessly about axle breathers, so one day I decided to slide under the 40 on the creeper to check out mine. Well I had a hard time finding them cause they weren't there! The only hose traveling from axle to frame is the brake line. Also, at the t-piece where the single brake line is split, (I'm assuming where the breather attachment is) the axle is very wet all around. Also, 3 weeks ago, I took my 40 mild wheelin, water about floor deep, and mud about bottom of axle deep. And I am about to go again on thurs. I have got time on wed to do at least a provisional setup for this weekend. Whats involved and what do I need? Heard that the glove box is a common place to route too.
