Leaving hubs locked in 2WD

Looking for a second opinion...

I have a 97' F250 powerstroke with manual locking hubs. After some googling it seems leaving the hubs locked full time is an ok thing to do (in 2WD of course)... what are your thoughts on it?

If I'm in a situation where I'll be needing 4 wheel drive sporadically, like the few days we get some ice, or out on a hunting trip, I'll leave the hubs locked.

But, I found that if I get to highway speeds for more than a few minutes my front end starts to make noise so I don't do that. If I wasn't swapping to a D60 soon I'd change the diff fluid and inspect/replace the internal spindle bearings.

Most people opt to have the hubs unlocked as much as practical as it takes energy (fuel) to spin the axles.

I envy those that know exactly which modification to make and in the most logical of sequences. But not enough to trade for my meanderings and misfires.

If they were meant to be engaged all the time, there wouldn't be the option to unlock them. That said, you shouldn't feel compelled to lock/unlock them EVERY time you do/don't use the 4WD. Typically, in places where there's actual winter, you lock the hubs at the first sign of snow, and unlock in the spring. Likewise, when we go to our cabin, which requires a short off-road drive, we lock in when we arrive, leave them locked for local trips on/off road, and unlock for the trip home.

Our '85 IDI came with manual hubs from the factory, and the owner's manual recommends driving with the hubs locked for at least one mile at least once a month, whether you use the 4x4 or not.
