2013 front end/ engine rattle/grind

Hey y’all, just signed up!
I don’t know if it’s an alignment issue or front end issue.
Here’s the details:
2013 Tacoma 170k miles
4 cylinder automatic.
Everything is stock.

I have a grinding/rattling sound between 1500 and 2000 rpm. I usually hear it when I let off the gas and slow down. I just heard it while accelerating but always between 1500 and 2k.

any ideas, TIA

 

Could it be a heat shield rattling? Have you crawled underneath and tapped on any of the exhaust?

 

No not yet, sounds more like front end. I can do a check this weekend. I know it needs alignment from my tires. A loose shroud would be such an easy fix.

check were the airbox tube goes through the inner fender as well.

 

I have an update for y’all, it ended up being a sheared bolt in my splash guard plate on the passenger side!
I appreciate all the advice.
