Front differential vent

Hey guys, I have a 93 yj when looking under the front end I found a rubber hose dangling down. When I found the top end its looks like is a vent hose of some king and has a plastic vented cap on it. The bottom end has a plastic fitting that looks like it should plug into something. The only thing I can think of is the vent for the front Dana 30 differential. However, I cannot find a hole in the differential for it to plug into. Any suggestions???

Should be on the back side of the diff, near the top, passenger side. At least that's where mine is on my 95.

Do yourself a favor and run all vent lines up high into the hood area so you don't suck crap into them.

Thank for all the great information. Now all I have to do is brave the Seattle rain and crawl underneath and find the right spot. The pics and diagrams will help a lot. Thanks again guys.

Hi Guys,
I also just discovered the same thing on my 99 Grand Cherokee. I noticed some oil on my front differential. After investigating, I found a hose dangling there as well. How could it have popped loose? And is there something else I should be concerned with now.
Thanks a lot!

Haha, I got a question related to this topic, I have a front diff. vent hose connected to the front-end pumpkin but when I backed into my driveway it was laying on the ground disconnected from the front upper location of it, I can't figure out where I connect the hose to?! I have a 2001 TJ lifted but I have the 60th anniversary & they put Dana 44's on the rear, but I dont know if they put a D35 or D44 on the front but could someone help me on where to mount it??

Hey guys, I am having the same issue. I know where it goes but I cannot get the darn thing to stay in there. Mine has the plastic piece attached to the hose. Do I need a new plastic piece, does it snap in? Can someone help? Would appreciate it!

If you look at Mean Max's picture, he has a small hose clamp. Found in any parts store. Use that to hold it onto the differential vent.

Yes a hose clamp would work if I could get the little plastic piece attached to the hose to stay in the hole on the differential. Putting a hose clamp on the hose would just keep the little plastic piece in the hose, it would not keep in thing in the hole on the diff. Sounds a little complicated of what I am saying, maybe I could attach a pic. Would that help?

When I had my axle in the shop for the locker installation I had the guy tap the vent hole and screwed in a barb fitting; no more loose hoses.
