Chirping noise around belt still persistent after replacing pulley (2008 TL-S)

Hey guys,

2008 TL-S / 75K

I have this wicked annoying noise coming from around my belt. I did research on here and came to the conclusion that it was most likely my tensioner pulley. Well, I replaced the pulley, bolt, and bearing, and I still have the same noise as before. Not the P/S o-ring thing either. I think I might just need a new belt? However, my current belt was not showing any problems or signs of wear. Suggestions? Link to the noise I uploaded on youtube below..



Thanks.
