I was questioning the grooves being cut into the spacers by the seal lip and dirt. Maybe I should have been more specific. As the grooves get bigger and deeper it will allow dirt and water to enter the wheel bearing area. It doesn't sound like you were experiencing any of the issues I was asking about.
