there is a rubber hose that comes from the top of the rearend and runs along the side of truck somewhere. found it dragging this morning. i did a search site is not running to well. what is this hose for and do? i just figured that when i lowered my truck my exhaust pipe burned threw it.. need to get a new bent pipe. but whats the rubber hose for?

 

It's a vent tube. The hose is to extend it up high so that water wouldn't get into the diff. if submerged in water.

 

damn.. ok so the whole point is to keep it up high.. cool man thanks.. i will figure something out... thanks a bunch.
