manually locking hub whistle

I noticed a slight whistle last year coming from my front left hub. I pulled the hub and greased the gears as best I could and it sort of went away. Now this year it is a little louder. It only happens when the hub is locked. Is starts around 20mph and goes away at 40.

Is the bearing in the hub shot or is this normal. 4x4 works fine and there is no visible excess wear on the gears. The truck has 93k. Thanks

Are the hubs stock?

Yes they are. The noise doesn't even sound like any bearing squeel I've heard before. Its kind of a fluttering squeel. Its hard to describe. I've tried recording the noise but nothing recorded on my phone

i would start by pulling your hubs, then reinstalling them on the opposite side. See if the whistle follows the hub.

I don't know of an aftermarket locking hub for the 05+ models. I would say the axle support bearing has gotten dry and needs replacing before it galls the stub shaft.
