This picture is all I have to go off of, I don't own a XJ. Asking for someone since I can't look at it myself in person yet. 99 Cherokee 4.0 front driver's side. They say that when they got up under there to look, they couldn't tell where it went (no jack). Also probably unrelated, they said that they could see coolant on the underside of whatever was above where the hose led. Just asking before I go look at it myself. As you can see the hose is slightly kinked/collapsed, which is what brought up the question in the first place. Thanks.

 

Guessing I am looking at the drivers side front. Also guessing that is the front diff breather hose. If so just needs to be secured back up probably.

 

Yep looks like diff vet hose.. Just push it back up and secure.

 

Looks like a power steering hose or something.. looks way to damn big for a diff hose. A diff hose is only like 1/4". That looks like 3/4 or 5/8 but the picture is pretty deceiving.

 

its the vet hose for the diff.

Here is my diff breather..

 

Well you can't argue when the numbers line up! LOL.

 

 

If that's a power steering hose, he's got bigger problems lol
