    Asking this online is gonna be like finding a needle in a haystack for Yall but it's worth a shot.. Coming from the engine, This truck has a rattle/buzz from hell from 1400-1600 rpms which seems to be where the engine likes to sit when cruising of course. At no other point can I hear it...I looked under the hood while dad held the gas and brakes at 1500rpms and the noise stayed the whole time just buzzing away. I narrowed it down to what seems to be the alternator? Weird. Spent an hour under the truck banging and trying to shake anything I could but nothing. I'm gonna lose my mind over this. I hope this is something that is common but I'm sure it's not.

    The alternator should make some noise unless the belt or bearings in the alternator are going out...

    I'd like to post a vid of it but idk how to get it on here...my name is newb for a reason. What is the evap purge vsv? Can U unabbreviate it for me.

    Spoiler alert: Id put money on this noise being a loose bolt/nut somewhere. The sound is too perfect.

    Shocker here...trying to get this video uploaded is going just as planned. Failed. "The uploaded file does not have an allowed extension" is what its telling me.

    I HATE TECHNOLOGY!!! Why cant it just WORK?! I should be able to click a button and put the video in this message. But I guess that would make too much sense.

    Ok rant over. Anyone who wants to help feel free.

    Does sound like something loose. Not sure what though. And weird it's only at lower rpms

    Hmm, sounds like some sort of metal or plastic plate is vibrating. Thoughts:

    Maybe try to feel around on the back side or under side of the alternator for a loose bolt. The alternator is bolted to a plate that is then bolted to the block if I remember correctly. Maybe try to loosen the serpentine tensioner and see if the alternator sags or if you can wiggle it.

    Other thoughts based just on the sound.

    *Loose fan shroud
    *Loose skidplate
    *Bolt on a 'spinner' on the serpentine system is loose.
