Tundra squealing

I have a 2008 Tundra and for about a week or two it’s been squealing, and the more you accelerate the louder it gets,but it’s weird because it’s fine some days no squeal then other days it will not stop squealing. Any one having the same issue ?

 

Belt slipping? Weather and or humid / moister making it inconsistent?

 

Front of the engine? Belt or pulleys. I had it and it was a pulley, but was time for a timing belt anyway, so all done.

 

Just went through this with my 2017. Thought it was the belt tensioner initially - changed that and the idler pulley to no avail. Used a stethoscope to determine it was coming from the alternator pulley. Changed out alternator and problem solved.

See if you can pinpoint the noise to narrow the list of possibilities. Maybe start with a new OEM belt and see if anything changes.
