Another combination of one bad part leading to another.
Bad wheel seal leaks diff. fluid, fluid level goes down, bearing doesn't get lubricated anymore.
Your best bet is to get both seals and wheel bearings replaced at the same time. Not much additional cost but if one goes bad, the other is not far behind.
For example, you wouldn't change just 1 wheel's brake pads and not the other.
