The bearing in my tensioner pulley actually froze up today. I was dropping off my sister off at school and it just shut off when I came to a stop. I started it back up, and I put on a smoke show for her friends the smoke was from the belt melting as it was rubbing against the pulley

 

I took it into toyota and its getting a new harmonic balancer and a tensioner pulley. Btw the crank pulley comes with a the harmonic balancer.
