There is a thin coating of oil that radiates out from the hub, covering the disk with the holes in it, and as you can see on the tire, on a long ride (SantaFe) it will eventually gets onto the tire. If I stay away from synthetic gear oil, this is lessened, but still does occur. Is this something "to live with" or is there a seal I can replace without too much fuss?

Also - is there any maintenance to do on whatever is on the other side of that disk with the holes in it? (It looks pretty dusty in there.) I tried to take a peek: The retaining ring easily comes out, but nothing else budged.

Note - on both photos, the slight color directly down from the axle-hole is a very light fluid- there was just a dribble - I'm not sure if it was water/maybe condensation, or what. It certainly wasn't 80/90 wt oil.
