Not really. Good quality unit bearings (like Timken) are simple, strong, and last plenty long.
I picked up some Explorer hub stuff from a guy that that was modifying it for a jeep TJ. (He'd given up). I got no further. Pretty small/flimsy mechanism to work with the 5x4.5" pattern.
Or the bearing is simply made differently.
I believe Chevy and Ford also began producing 2wds around '99 that were just using 4wd unit bearings with a tin cover pressed on over the splined center hole.

I was mainly thinking about fule milage because it makes a big difference without the front drive line in, mileage wise around 4 to 5 miles a gallon on the crd depending on how hard you push it. I dropped from 37 miles to the gallon to 32 to 33 miles to the gallon when I reinstalled the front drive shaft. If it had locking hubs to where the wheel bearing were the only moving parts instead of the front drive train and transfer case being turned it wouldn't surprise me if it wouldn't get around 40 ± mpg.
I would doubly recalculate for accurancy. If it was that significant on a V6/6spd I would have noticed. This is hotly debated in Dodge Ram forums, and consensus of perhaps 1mpg difference. The trade-off is having the front drivetrain stagnant and possibly seizing up from lack of use, vs being exercised.
Edit: the nv242 wouldn't be very happy in full-time mode if the hubs got left unlocked by accident.

I saw I slight improvement in gas mileage when my front driveshaft was out. from 20 mpg to about 22 mpg. I removed it to replace the starter and notice the rear CV of the front shaft was shot, so I left it out until the new one arrived

Why would I recalculate for my 3.7 it's 37x 13.5 tires on it doubt I would see much difference but the 2. 8 crd went from 37 to 32.6. the diagnostic tool I have calculated it for me. I don't have any reason to doubt it as of yet. Till it eventually gives me one
I don't understand why why a nv 231 or 242 would have any issues not being spun by the drive train and not wearing out the soft side of the drive being unlocked . Only issues I can see is the same as what once was. I'm not trying to get out in the mud and lock the hubs in because you forgot to do it before you ran off in the mud hole that's the only issues I really seen with lock-in lock out of hubs.

I forgot about the part if you don't use your four wheel drive enough to let it sees up you don't need a four wheel drive you're wasting your money
And I keep that I'm driving it probably been sitting around for a few years and a field now they're driving with no driveline once I put it back in I'm sure it had thin
gs to free up. Actually I have no doubt if anything it's free up because my first experience putting it in drive like dumping the clutch the torque converter was locked in I hadn't tested it after I drove it 5,000 miles since then but that was the first experience between driveline and no driveline I had.
And after putting the front drive on back in it I made it about 200 miles before it destroyed the boot and slung grease every where but nevertheless I don't get 37 miles to the gallon any more and the front drive shaft is the only thing different that i have done .
