Locking hubs

[Jean-Luc]

I have a Silverado 1500 2019 high country, 6.2L heavy trailering package.

 

i have noticed that my front shafts are actually turning in 2WD mode,  when I switch to 4wd the transfer case engages.  
is this a new set up my previous 1500 Silverado used to disconnect my shafts from the front hubs 

 

let me know,  thanks

Been that way since they started using independent front suspension. I think 1988 was first year for pickups.
