I'm changing the front tire this weekend, have the wheel off. Everything looks good, including the seals. It does look, however, that the outer seals have never been in contact with the axel. When I stick the axel in, there is a bit of daylight between the seal and the axel. Is this normal? According to my logic, the seals should be in contact with the axel. The wheel bearings are sealed. I'm talking about the outer dust seals here.
