This is not like locking hubs. Only the right wheel is disconnected and the inner half of the right axle shaft turns in the reverse direction to the outer half. This of course means that the differential spider gears will be spinning around like crazy. I have heard that this concept was first tried back in the early 70s but was quickly abandoned. It definitely is not used by everyone’s Chevy, Ford, Ram, Toyota, etc.

Interesting, as I recall the early 70's you had: manual lock out hubs, automatic hubs, full time 4X4, or drive flanges.
Please share these other examples.
Thank You
Look at Chevy IFS since 1988 to today, Dodge ( Ram ) trucks since 1994, Ford IFS 4X4, Toyota pickups 89 and up, Tacoma 1997, (AAD) and up,
Jeep Cherokee 84 -90 and Wrangler YJ's pre 95.
About the ONLY exception is Ford Super Duty, and some older Toyota HiLux pickups, some Nissans, Samurai's etc...( lock out hubs ).
Please take a look online at CAD, ( Center Axle Disconnect ) All these examples work the same way, disconnecting one axle side from the diff. allowing free rotation through the spider gears. Just like new Jeeps.
Some of the older systems used vacuum to move the shift collar, GM used a "thermal actuator" to shift ,( Real Dumb )
Most newer systems are electric shift.
Personally, I like the TJ and 91 and up Cherokee direct drive setup.
However if you had extreme lift and driveshaft angles, lock out hubs would be your friend on the highway !
If this was the only issue with new Jeeps I could get around it. However with all the other multitude of of electronic nannies, electronic power steering, auto start / stop, 2nd mini battery under the floor, and touchscreen controlled crap that is less than reliable count me out.
Hell, seems like the new Jeep has issues even building a 3.6 pentastar that doesn't missfire.
