4 wheel drive and lock-out hubs

I bought a new chevy pickup with 4wd. Instead of the old stick in the floor I'm used to to access the transfer case, it has push button on the dash. It also has automatic hubs instead of the lock-out style on my current, older Ford truck.

Would it be worth changing to lock-out style hubs on the Chevy ( Silverado 2500HD ) for the sake of increasing gas mileage ??

Nope. What you have is better and most efficient for the platform you have. Leave it alone.

If you have a new Chevy you don't have hubs anyhow.You have cv joints and an actuator that egages the differential when 4 wheel drive is selected.The axle shafts turn all the time even in 2 wheel drive but are not driven by engine power.
