What's this hose that looks disconnected?

Over the weekend I took the XK to get a tire patched that had a slow leak (turns out I had TWO nails in it) and while it was jacked up I noticed that there was a rubber tube that was attached to the passenger side of the rear axle and the other end ran up to the passenger side rear wheel and was disconnected. I thought I had pulled it loose while wheeling so I took it to the dealer and the attendant took a quick look and stated that it was used to fill the differential and that it should be like that. An open end tube that goes up to the passenger side rear wheel to fill the differential?! Isn't that what the hole on the top half of the differential is for? If this rubber tube IS used to fill the differential then why is it not capped? Could it be something else? When I first saw it I thought it might've been a brake line but this thing goes straight to the axle.

Can anybody explain exactly what it is and why it's designed that way? Thanks!

That's too funny... "to fill the differential" through the vent tube would take the better part of the afternoon. Hehe... that's awesome. It's most likely your axle vent tube... don't plug it. It is designed to vent off gasses that occur when your axle components and fluid heat up and cool down... just like your engine, friction happens and there has to be a place for air to go. If you plug it you will eventually push past a seal and you won't be happy. Most attendants don't know squat.

Lol that's what I figured and thought I'd ask some people who do know squat.

Thanks for the responses!

Thats definately the differential vent tube. Comes off the passenger side axle tube on the rear axle and goes into the wheel well area. That other end really isnt connected to anything. That end is the vent. But it does have a clip that holds it from dangling down.

Go to a dealer and look underneath a new one to see where and how it is fastened.

The end attaches to one of the upper strut mounting bolts. Its a black plastic, and round, with a hole in the center to mount on the stud.
