Hi,
There isn't a front axle actuator on this vehicle. The 4wd is controlled via the transfer case.
Looking at the first pic you sent, it looks like there is a one-way breather at the end. If that is the case, that should attach to the differential. If you follow the opposite side that isn't disconnected, see if it goes to the differential.
I copied one of your pics and circled the end. Is that a cap at the end of the hose?
Let me know.
Joe
