Hey all!

I tried searching, but since I don't know what it is or what to call it, search was pretty useless: While looking for oil leak found this hose dangling under the driver's side, hanging over and rubbing the 4x4 drive shaft (goes to front diff). You can see the shiny spot on the drive shaft. It goes over the top of the tranny pan, and i lose it after that. I see no other end to connect to. Anyone know what this does, and is it supposed to be routed to this location? After all these years, I haven't noticed it before. Thanks!
