Hello all

Trying to understand more and diagnose failing bearing sound.

For the decoupler pulley of the alternator, if I understand correctly, the pulley should spin freely on one side, not turning the inside parts of the alternator, but be engage when spining the other side, right?

Cause mine is engage both sides. I more and more think it's the alternator bearing or pulley causing my strange noise.

Thanks
Chris
