I don't know about '07, but my '08 Rubi did the same (similar) ONE time after some pretty good off-roading
Mine was on the drivers side about a foot back from the front of the engine !!
I found the front diff had been overfilled and it would seep out the top of the vent tube and find its way to the garage floor, about a foot behind the diff
Did that for about a month--then NO MORE
