It's better if you have the system set for the driving conditions you encounter (switching back and forth). But if is still snowy or wet on the roads, you'll be fine.
You'll cause undo wear and tear if you leave your truck in 4WD all the time. Your vehicle wasn't built for that type of service.

If the road is dry do not drive in 4wd. When you turn your wheels with the trans case in 2hi the front wheels turn at different speeds. the outside wheel turns more than the inside one due to it has further to go to make the turn. When 4hi is engaged the trans case turns both wheels at the same speed. So if it is dry the tires can't slip to make the turn. They end up binding up and cause havoc on the trans case. Make sure it is wet or slippery out before engaging it. So yes shift in and out of 4wd or just leave it off and slow down.

Best read your owners manual before driving in 4WD on dry of damp pavement. If your truck was designed with universal joint protection it's safe - but even them it is problematical.
All four wheels must be free to either slip on snow and ice, or their differences (tire wear etc) must be taken up by a universal. Your auto transmission has nothing to do with it.
So read that manual - it's cheaper than a repair by far.

Just leave it in Fourwheel drive till the road conditions are better.
You won't hurt it.
switching back and fourth between 4 wheel drive and2 wheel drive all the time is worse.

i understand all pickups immediately have an computerized mode for his or her move circumstances the position it is going to change from 2hi to 4hi proper away at the same time as needed. regardless of the indisputable fact that, i'm not particular in the journey that they're going to change to 4lo proper away, i have self assurance their's nonetheless a procedure for that (regardless of the reality that i'd be incorrect on that). GM has had an computerized move case on account that 1998. many of the time the truck will run in 2hi yet when it detects wheel slip it is going to proper away flow to 4hi with out any motive force enter. previous to 1998 GM had a push button depending move case that grow to be not computerized yet should be pushed at the same time as transferring (once again from 2hi to 4hi in hardship-free words). previous to that GM used a floor shifter the position you ought to change from 2hi to 4hi at the same time as transferring, to flow to 4lo try to be transferring at about 3mph. Any cutting-edge pickup is going to have both four wheel drive on-call for or computerized four wheel drive. And those are all going to be authentic area-time four wheel drive structures with hi and lo ranges. you'll frequently see AWD in smaller SUV's/CUV's that are finished-time awd yet haven't any lo decision.
