I was under the truck and noticed that the hose coming out of the back of the diff had been run up the firewall and plugged off by the previous owner. I figured that that it was not suppose to be plugged (otherwise why have it) so I snipped it a bit shorter and zip-tied it to the suspension arm.

Where should this hose be routed?

On a TJ, that hose runs up along the driver side of the radiator and is supposed to have clamps that are held in place with the fan shroud bolts. Mine fell down once and the one-way valve fell off. I just put it back in place and zip tied the end a little to attempt to keep water from going down the hose. But yeah, it is supposed to terminate near the top of the radiator on the driver side.

That's your differential breather. It is supposed to be that long to prevent water from getting in the differential through the breather, especially if you dunk the axles under water.

Go the the auto parts store and get some new tubing....a section long enough to run the hose back up to where it was.

Sometimes it's better to ask first before acting.

The hose isn't truly "plugged" at the end. That's a one way breather for the axle. It won't allow anything to go down into the axle housing.
