I have 99 limited and my vent hose is off the front diff. It is still connected up above, it has came of at the differential. I have been searching for awhile but I can not figure out what it takes to connect the hose back to diff. Does anyone have a diagram and or part number?
No, that is the wiggle cap at the end of the vent hose. It lets overpressure go out and prevents water/dirt to come in.
The breather nipple originally seems to be a press fit plastic one, which should be on the top of the diff housing. Some people fit a brass nipple with thread, but the diff should be on the bench for that: http://www.moabjeeper.com/articles/t...?articleID=228
