Squeaky front end at 65+ MPH. Troubleshooting Ideas?

I'm driving an '04 Taco w/ about 150k miles. I recently noticed that the front end squeaks when I start getting above 65 MPH. I can't hear the noise at slower speeds. Also, at 65+, I can't hear any noise if I start to bear right. Any ideas on where to start trouble shooting it?

Thanks in advance for any help.

I just had a similar issue and believe it or not, it was from having front wheels that were out of balance. Post-balance, no squeak.

I didn't realize how badly they needed to be balanced until it was done. Sooooooooooooooo smooth now...

 

I'll check that, too. Thanks for the response.
