since these roxor are basically a cj3b then another similarity is that if you get it in a bind you will either twist a rear axle shaft or more likely spin the axle in the hub. this was a good design intended to protect the much more expensive and hard to replace ring gear and pinion.
Oh man that reminded me of my adventures with mid-50's Willys Wagons that I each owned a single year. Those were originally mostly sold to forestry crews etc, so at 20 years old they were pretty thrashed. I decided the first one simply wasn't safe on the road. A severe side angle could lift the body off its rusted mounts on the high side, and I shook the radiator loose on a dirt road into Bodie, a mining ghost town a couple hundred miles from home. I always made it home but after a while I realized every hour in 4wd cost me an hour of repairs.
I replace that one with one sold by a body shop that looked a lot better, and had the A/C and Ford 292 V8 from a Ford Galaxy 500 transferred into it. With the huge torque and low gears, and over drive, it would go up freeway grades full speed without even breathing hard. But ... on one adventure with friends aboard, I almost didn't make it home. Climbing the bluff up a Jeep trail leaving a back road, I twisted a spiral crack in the Ford/Flathead/Chrysler/Jeep bell housing stack of adapters and lost most of the ability to disengage the clutch. Made it home! But it took forever to find a replacement Ford Y-block to Jeep bell housing. Repaired and sold that one. Years later when I spoke to a subsequent owner he said the Warn overdrive's internal gears had stripped from the torque after awhile.
After that I bought a Navy Surplus Wagoneer that was indestructible, except its (unmodifed!) wiring was awful. Near killed me when I was tinkering with the dashboard lighting intensity on the headlight knob, and met a logging truck unexpectedly in a curve - and everything went black. I could still see by his lighting as he went by - but then nothing. I locked up the brakes and prayed I was still aimed in the right direction instead of over the bank into the creek. I drove that several more years but didn't trust it quite as much. I finally bought an Isuzu Trooper new and never hand any of those problems in 15 years.
Early jeeps are fun but I understand why some people trailer them in to where they are going to drive them ... ... its so they have a way to get home.
