    Hey guys! Just looking to see if anyone can point me in the direction to diagnose where this noise is coming from. It’s getting progressively worse over time and I’m going to fix it before it gets worse just trying to identify which pulley or bearing I need to replace. Trying to upload the video now.

    If you think its coming from one of the idler’s under the serpentine belt, pull the belt and rotate the idler(s) by hand. A bad idler will feel rough (different).

    I have a long screwdriver I use just for that, put the tip near where you think the noise is coming from the handle to your ear. Try another spot until you hear the noise it will be obvious. Tip from an old fart mechanic.

    Don't know what year and mileage but usually if one is going others are not far behind so if you are keeping it do them all and be done. Check the tensioner pulley too.

    Just replace them all. They aren't that expensive, even from the dealer.

    I probably don’t have to tell you this but be sure to replace the belt with a new OEM belt.

    Like others have said, if it's one, others will follow. Purchase a kit and replace them all.
