the hole is on the drivers side about 1 ft inboard of the leaf pack. directly ontop of the axle and slightly towards the backside. looks sorta like a spigot tip.
there is a little rubber hose that runs from that nipple to somewhere higher up near the fuel tank.
when this breather tube is disconnected, it's an open path for water/dirt and other crap to get directly into your axle. My breather tube keeps popping off. Thats why I asked about his...especially since he is in the mud/much and water has a better chance of getting inside
