front differential help
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?
Thank You

Re: front differential help
should be straight forward... if you don't see the nipple sticking out of the diff maybe it broke off.. some posts say its just a plastic piece pressed in too.. nothing sticking out your hose?

Re: front differential help
I am missing the plastic vent part. I figured there was something that the hose needed to be connected to. Looks like number 12 on that picture is what i need.
Thanks for the help.

Re: front differential help
Well is this what I keep coming up with but, I am not to sure if this is it. This looks more like it should go above and not into the differential?

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:

That is what I was thinking.

Re: front differential help
Most probably an axle shop can help you out with the right nipple.
