the seal is to the outer hub surface. I t can leak there. There isn't much that you can really call a seal between axle splines & hub splines. There is a big rubber band around axle just behind the hub, but......? I apply liberal silicone to splines before installing hub & hope for no leaks. Helps to not overfill.
