My truck also has developed a loud metallic chirp when first fired up, coming from the left front. I took the belt off, spun the vac pump, PS pump and A/C pulleys by hand. No noise, smooth bearings.
Idler pulley quiet (but not perfect). The tensioner pulley was a cheap plastic one and it had a rough bearing that would "catch" sometimes when spinning it, and some wobble too. So I drove into town and got a new metal one (Made in Canada) for $27.99 at O'Reilly. Popped it on and everything's quiet again.
