I’m not new to 4 wheel drive vehicles by any means. I have had and driven many in all kinds of conditions and know that you can’t turn them hard on bare ground etc. So you take them in and out of 4 wheel drive as needed . Bare parking lots etc. My 2022 3500 ho aisin gets real jumpy and floppy even when on ice or hard packed snow. I have the button on the dash model. It’s constantly in and out. . It gets pretty bad at times the front tire flop . I get a little concerned about tearing something up. Open for discussion thanks

As long as there is give it'll be fine. Just don't do it on bare pavement or concrete. These systems are very durable for the most part.

I am in and out of 4x4 on my work 3500 all the time.

I really hope high up on the wish list that there would be a full time 4x4 mode like there is on my 1500 EcoD on these trucks in the next revamp. My gosh would it be so nice.

A Cummins with full time/auto 4x4 mode with a solid 8 speed transmission... I'd be drooling.
 
I’ve wanted a full time transfercase for years!

I’d like one like our 4Runner has. 2 Hi, AWD Hi, AWD Low, 4wd Hi, and 4wd Low.
 
In the 80 s in Wyoming we drove 350 Chevy 3/4 ton 4x4 4 speed 410 rear pick ups. We only had chains for the


front. Don’t ask me why wasn’t my decision. We would run them hard and would blow the front ends out of them. I spent 18 hours in a raging blizzard because we couldnt get back to the hiway 8 miles away. Stayed with the pickup 40 gallons of gas saved three of us . Storm broke the next day and they sent a helicopter to bring us out. Guess that’s why the front flop really bothers me . Can I tear it up on a hard turn on ice or snow if I give it too much power . We have 60 inches snow and sometime you have to drive like hell to make it and it’s not all straight road etc.Don’t really hear of them going out I guess
 
I am in and out of 4X4 a lot on dry concrete and pavement in my 2018. Anytime I park "Nose Down" on my steep driveway (say to unload something out of the bed because I own a 3500 for a reason or three) I put it into 4X4 as the rear wheels alone with the parking brake on has allowed other pickups to slowly slide down the driveway. It hangs up now and then in 4X4 requiring the usual shift to reverse, etc. to unbind it. It hops real good to remind me when turning it's hung in 4X4. I have the floor lever 4X4 that takes it as a suggestion to shift into 2WD...

You can break things, but, you got to try hard. The shop that did the engine on my 2003 had a RAM 2500 in with an exploded transfer case. It was stuck in 4X4 and the owner decided it was ok to hit the freeway on dry road at speeds of 75 MPH+ in this condition. o_O What's the worst that could happen missed the catch on fire from all the oil and fuel let loose as the dive shafts were no longer supported ... just by luck. The insurance deductible, if they even covered it, is way higher than a tow that most policies add for little money. And it had to be towed anyway after they broke their known malfunctioning pickup.

We have seen a lot of snapped axles, even on 2WD, when operators are trying to rock stuck things out of the oilfield mud. It's a known known that GM's Gov Bomb locking rear end can go off when it decides to lock. We did training to keep MPH and RPM low, IE throttle back, when spinning because the sudden traction at the bottom of the mud would bring the tire to a quick stop. At high RPM and sudden traction an axle would snap. This advice to keep RPM low is even in some owner's manuals.

I still recall changing out dried out grease and worn out auto locking hubs in a 1988 1/2T Suburban with dad. The front diff oil was a whitish color when we changed it. The broken part of the ring gear in the rear was a surprise when we pulled the cover to change the oil. Yeah, learned me then and there the cover ALWAYS needs to come off for an inspection when changing the diff oil vs. the suck it out and put new in.
 
I sure miss the New Process NP203 transfer case in the 75 - 79 Dodge Ram Power Wagons I had. AWD with a locking transfer case differential. Hi-Loc - Hi - N - Lo - Lo-Loc.
Simple, Heavy Duty with mechanical shift and go-anywhere-in-all-conditions attitude.

I've done this before when loading trailers if I knew the machine may have a chance at pushing the truck and trailer, especially on loose dirt. Works like a charm.

My friend converted his full time Ramcharger to Warn Hubs.

I tried that on one of my '79 SWB W150's "attempting" to follow the crowd in search of some semblance of economy.
How does he like that conversion?
My experience:
1. You lose the AWD feature, which is quickly noted when encountering snow - ice - wet - gravel - dry road conditions on a route. Right foot becomes your traction control (-)
2. You gain a 2WD Low range (? +/- ?)
3. You DO NOT get better fuel economy (-)
4. You lose the ability to shift from AWD to Lock position on the fly (-)
5. You have to get out to engage the hubs when the goin' gets tough unexpectedly (YOU get dirty) (-)
6. You get stuck sooner than you would have with the original designed setup - oops...hubs first...:mad: (-)
7. Your wallet is a lot lighter (- $)
