There is a loud shop vacuum noise coming from what turns my belt like something came loose. Loud air sound pulse sound like bearings are in There loose spinning around. Like some bearings are loose in a shop vac. What is that noise? No check engine light or anything. I don't own a code reader.

Hi,

Chances are it is exactly what you described it as, a bearing in one of the belt-driven accessories.

Do me a favor. Take a pic of where the sound is coming from and upload it for me to see. That will help me.

I attached a pic below. If you are unable to get the pic uploaded, take a look at the pic I attached, copy it, and circle the component making the noise.

If you want, here are the directions for the removal of the belt. Remove the belt and by hand, turn each of the belt-driven accessories to see if you can locate which part is making the noise. Let me know what it is and I'll help you get it replaced.

3. Move the auto-tensioner (A) to relieve tensioner from the alternator belt (B), and remove the alternator belt.
