Weird noise coming from my front, passenger side wheel well - Need help diagnosing

As the title mentions, I have a noise coming from the front end of my '07 4Runner that for the life of me I cannot isolate. It sounds like a hamster on a squeeky wheel if that makes any sense. It is definitely audible in the cabin with all of the windows up. Below is what I have been able to figure out, I just don't know what component is making the noise specifically.

- It is always coming from the front, passenger side wheel well. Never the driver side.
- It only happens when it is cold and it happens consistently throughout the winter. It went away this summer and with our first cold spell a few days ago here in CO it came back immediately.
- It almost always happens when I am turning left, not right. Sometimes I can hear it when I am driving straight but it usually happens when I am turning left.

I just learned to ignore it last winter but since it appears to have risen it's ugly head again, I figured I should try to address the problem before it gets really cold out. Especially if it is causing wear on something that I will eventually have to replace. It sounds as though something needs to be lubed but I don't want to just start throwing grease and WD-40 at every moving part in my front end without figuring out exactly where it is coming from. Have any of you experienced this or have any recommendations on where I should start looking? Unfortunately I cannot duplicate the problem when my 4Runner is stationary which makes finding the squeak that more difficult. I am running wheel spacers which almost leads me to believe it could be a wheel bearing starting to go but I don't know that for sure. Any suggestions/ideas would be greatly appreciated.

I'm thinking its a hub or it could be a crack in the manifold causing air to squeek out.

good luck buddy!
 
I'm pretty sure that its not the manifold but it could be the hub or hub assembly. I still think it could be the wheel bearing but I'm not getting any shaking or wobbling coming from the front end. The fact that it only happens when its cold also leaves me scratching my head. I would think that something needs to be lubed. Does anyone know if there are any zerk fittings in the front end or can think of anywhere else I should be looking?
