'07 Denali XL Weird Whining noise?

[jafount]

Just started out of nowhere. It kind of sounds like the noise the off-road tires on my Silverado make on the highway.

Anyone know what this might be?

Front Hub Assy / Wheel Bearing

Jack it up and wiggle your front wheels/tires up and down. Then roll/spin them.

That should produce the noise unless it might be the rear end or something like that.
