Also - doesn't somebody make some sort of deal where something goes in the middle of the driveshaft, and you leave the vehicle in 4X4 with the hubs locked and the part in the middle of the driveshaft switches on and off, to make the driveshaft turn the wheels or not. Something like that?

If you want to leave your hubs locked all the time and shift in and out of 4wd on the transfer case, there's no harm in doing so. Just make sure you're not in 4wd on hard surfaces. All that will happen from leaving the hubs always locked is you get a little more wear on the front axle gears and bearings and front driveshaft and maybe a slight drop in gas mileage. It won't hurt the truck. You can also replace your hubs with drive flanges if you don't want them on the truck, but there's really no reason to take them off.

Yeah if the weather is snowy, I do put the hubs in lock and shift in and out of 4WD on the fly with the manual t-case. I was just wondering if there was something else, to avoid the small gas mileage penalty and extra wear.

Some manufacturers have gone to a front axle disconnect system that gets rid of the auto or manual hubs, but it doesn't seem to be much better than the autohubs. Best system so far is the simple manual hubs
