Okay so my A/C makes some noise when I have it on, and the A/C belt wobbles as well. I am wondering if the A/C pulley is separate from the rest of the dampener? The noise and any vibration goes away when I turn off the A/C. Also I thought there was a tensioner on this belt as well, can't remember. So I am worried the crankshaft bolt might need to be replaced, but since everything goes away when I turn off A/C I am thinking it is something there, not in the Crankshaft bolt.
