Something under truck rattles like a tin can intermittently

[AlsMaverick]

I'm wondering if anyone has come across this. About 50% of my driving time contains a loud rattle from what sounds like a tin can being pulled from behind.
This just started a couple of days ago. It comes and goes. It does not change with speed except that it is a very slow rattle when stopped. I cannot associate it with tires, axles, engine, etc. I took a quick look under the truck and didn't find anything obvious, such as a loose muffler or exhaust pipe since that's kind of what it sounds like. Any ideas?

2024 2.0 ecoboost, FX4, 4K tow.

Thanks,
Alllen

Does it sound like a metal heat shield?

 

[RR - All the way]

I believe I would just "kick that can" down to the dealer and let them figure it out.

Exactly, I was thinking.
Have experienced and heard that "sound" over the years...

I've read previous posts where squirrels have stored acorns in the wheels and other places. Makes more noise than you might think. Do you keep your truck outside?

This happened to me and sounded exactly like dragging tin cans.

After six months of believing I was hearing a rock rolling around somewhere underneath our Toyota Highlander- I started to rip out the 3rd row seating false floor that's not easy to get to and boom found a golf ball there and we don't play golf- Previous owner must have dropped it years before we took delivery - Kind of funny -

if you have had dealer service, make sure they put all the bolts back in the skid plate, and that they are tight.

Late last night it just stopped.

Mine only makes that sound when it's cold, once it warms up it goes away. Im thinking it's a loose heatshield.

Squirrels have stored acorns in the wheels and other places, probably

Any rattle annoying.

Not related, but maybe it is, had a Jeep Cherokee that rattled. Turn out it was the cat converter, beads loose. They rattled when engine running. Had a muffle shop replace it. Quieter!

Few weeks after, Jeep issued a service letter About cat rattling. And would reimburse if cat replaced. Sent receipt, got my money back.

What year jeep?

1996 Cherokee Country. Loved that Jeep. My youngest son took over it. Started aging, trouble with it. He brought himself new vehicle. Not using it, but died anyway. So donated it to Purple Hearts.

Thank you for the reply.

Very straightforward design.
