Need help: identifying this rattle

Hey guys I have a 2018 Tacoma v6 and just recently began to have a rattle, which seems to be under my truck. Truck has 195k miles I bought it brand new, and just kept driving and maintaining it. This rattle is something new and it’s honestly kind of annoying lol. If you can help point me in the right direction that would cool.

the sound is kind of like a high pitch metallic/ scrapping sound. I can hear it at cold starts and then goes away. But then comes back when putting load on the truck ex. Accelerating normally and going up hill. Also if I accelerate heavy it does not make that sound.

here is an upload I made.

Thanks in advance guys

 

Anyone?

 

It's hard to tell from the audio. Maybe crawl under and take a look around while it's running. Nice work on the milage BTW

 

I don’t hear it

 

Lay under the truck and check each and every heat shield (when cold so you don't burn yourself).
