2014 GMC Sierra 1500 grinding noise under the truck

grinding noise from under the truck

Can we get some specifics?
Accelerating, stopping, turning, down hill, left, right.

I’d get whatever it is fixed if I were you.

… or when using the starter, or when idling, or… ?

:question:

Are there legs sticking out from under the truck? Could be someone snoring very loud.
