Worn bearings?

I’d think a very directed look at eack pulley, then deciding if you want to do all the belts as a 1-shot PM & spin each pulley (looking for flaws from grit) -then would be a super-fix to the situation.

LMK if you want me to come down, I am just up in Mount Vernon, never hurts meeting other locals.

My 80 is open ATM, I am doing another FAS but I can ease your way in the Ghetto-Tundra - any PM after Mon.

I have a spare set of OE belts IIRC under the Tundra seat I was planning for mine, but they’re cheap. You need ‘em more than me.
I have a extra-extra set in back my 80.

Belt dressing is a “shoot yourself in the foot” to longterm owners, glad others steered you away on that.

Hey Linus,

I will take a good look at each pulley today to see if they are off balance or if I can hear any bearing noise as others have suggested.

Thanks for the offer of belts, I got a new set from @NLXTACY along with alternator block and nut. It would be great to meet a fellow mudder if you wanted to venture on down south to Bothell. I think I am going to tackle this job this week, I have a long road trip to Spokane and Post Falls ID coming up next month and for piece of minds sake I would rather take care of this now. I will DM you after looking at my work schedule.

Oh and as far as belt dressing, yeah I did a little research on it and found out its a tacky glue like substance with might address the symptoms but doesn't fix the root of the issue.

Loosen belts and check each pulley for a grinding resistance when you turn it by hand. It really does sound like alternator or the AC compressor. Is it louder on the driver or passenger side?
