3rd gen grinding noise when reversing

I first heard the sound about a month ago while reversing when my wheels were turned and just assumed it was rub since it kind of sounds similar. Last night, I reversed straight back with my wheels straight and heard it so I knew it wasn’t rub. If I reverse and don't push the gas, it doesn’t make the sound. But when I apply a little throttle, it makes it.
It’s 2019 sport 4x4 with about 12k on it. Any ideas?

 

What mods have you done to your truck?

 

When you select reverse , you place force or twisting momentum in the opposite direction . Have you slid under the truck to see if any exhaust shields are rubbing ?
Are you automatic or manual transmission ?
Is it worse in 4x4 ?

 

Kings front and rear set right under 3” 1.5 aal. Skids, sliders.

 

Do

Automatic, haven’t tried to mimic it in 4x.

 

Hey,

Any update on this? My 2019 stick shift @ 10,000 miles just started exhibiting similar behavior. It's going in on the 29th for the fuel pump recall and I've mentioned it to the dealer

 

Anyone have any updates on this? My 2020 just started doing this too. If im in reverse it sounds like the front drivers side brakes are grinding/creaking like crawl control is engaged, but if im in neutral or drive that noise doesn't occur. Im testing this on a flat surface so it isnt hill assist kicking in

This started happening after i used crawl control the day before in some soft sand. Going to pull the battery cables and see if that does anything
