Crazy noise from belts?

[groceryrig]

Hey, hoping someone can help diagnose what this wretched sound is. Sounds like it’s coming from the belts. Maybe a horrific belt squeak that just needs lube?
It’s silent when accelerating above 15mph, and only comes back intermittently when at low speeds or idling.
Here’s a link to the Reddit post with video.

As in, the tensioner bearing? Or mixed bag, could be any bearing?

Are you able to change a bearing ?
If not go to a mechanic .

‘Twas the A/C belt tension luckily. Way off, and jiggling like crazy when running.

Psych, the noise is back. Just ordered up a new bearing for the tensioner. If that doesn’t work I’ll order a bearing for the AC clutch.
Will post any photos or part numbers as I go.
