FRONT WHEEL BEARINGS
Front wheel bearings are not serviceable. They have to be sealed to keep out the elements and there is no way to lube them. You should get 80 to 100 thousand miles out of them. Replacing them is somewhat of a task, but manageable.
"Unit-Bearings" I believe they are called. Either you love 'em or hate 'em. I prefer the traditional type myself.
on my fwd.. they are sealed hubs. i've gone 168k miles on it without service. usually, they are long-lasting.
