I'd put 20:1 odds for the front wheel bearing. That's *eaxtly* what
mine sounded like on it's way out. Pick up that corner of the truck,
and try to wobble the wheel. if it will wobble in all directions, it's
the unit bearing assembly. Looking at $155/side at Advance..... If
one is bad enough to be making noise, the other is likely rather tired.
No idea what would have caused it to die so quickly.

I'd agree - but a bad wheel bearing could also be causing this. Jack
under the A arm (so the knuckle is still supporting weight) and try to
wobble the knuckle assy back and forth with the tire, top to bottom.
Of course given your above symptom, check side to side wobble too, and
if it wobbles in both axes, I'l be expecting the bad bearing. If
that's the case, pull the tire, the caliper and the rotor, and see if
you can wobble the hub around at all.
Good luck!
