A hose to nowhere...on front differential

[ranhood]

First... thank you for such a great resource!!! I just purchased a 2004 Liberty, 3.7L and I'm doing some very overdue maintenance and TLC on her. Found a small rubber 1/2inch hose, comes off the front diff, connected to a metal elbow on differential. Hose goes up on driver's side behind radiator but not connected to anything!!? I can see a broken off piece inside that end of hose, corroded. My guess is it's a breather or overflow type hose/function. Any ideas?? (this is my first jeep!) If someone could please offer suggestions, helps?!?! Thank you, thank you!! I really do enjoy the info here!

It's the breather for the diff. That broken piece keeps dirt amd other crap from getting into the diff.

So I don't need to connect that end to anything? Does a small filter of some sort plug into the end of the hose? I was looking for tube or something that directed fluid back into the differential? (i guess the term "breather" refers to air?! - wow... i need help)

It's just a little hat-like thing - think chimney cap - that keeps dirt out of the breather. The breather itself lets air in and out of the diff, depending on the temperature. Oil expands when heated and contracts when cooled.

I think it is just push on hose fitting on the front differential that the hose connects to then it routes up into the engine bay, ending on a plastic fitting right below the battery.

Just answered this on the other forum, but on my 02 it connects to a small round hard plastic end that is attached to a stud on the inner fender below the battery. I'd attach (ziptie) it to something to keep it as high as possible.

This is where mine now is zip tied.
It was suppose to be connected to a bolt below the battery so I was told..:gr_grin:

Once you put a top plate on there are not enough threads remaining to hold it in it's original location.
I have mine zip tied like yours.

I moved mine to a bolt further towards the firewall, but not ON the firewall. If I have water going to where the breather is located...I have MUCH bigger problems. :emotions33:

Thank you LibertyTC... your jeep is clean and tidy! I will be sending pics AFTER some cleaning. (she's been driven hard with no love when I got her). Is that cap on top end a dealer only part?? I appreciate all the info!!
