While I concur with Hoges's recommendation to fix, it may be useful information to know that my seal has been leaking (very slowly) on the right front for many months. Each time I replace the diff oil, it still appears full, or full enough. YMMV.
Also, it is not good for us to drop oil onto the road, for those two-wheeler types, especially, so this is a good reminder for me to do mine. 
Let me know where you get your seal from
