Silly question here for the group. Took about a 4 hour road trip yesterday and when we got to our destination, found a rubber hose hanging underneath the truck. It is attached to the rearend on top of the casing about halfway between the differential and the wheel on the drivers side. I assume this is a vent tube of some sort. Couldn't find where it was supposed to attach, so I zip tied it up so it wouldn't drag. Any ideas where this tube might connect? Will it hurt to run it this way until I get it repaired? In the process of moving so don't have time to crawl underneath it to search for the connection point. Thanks in advance for any ideas.
