I obviously don't know enough about the 4WD system in our Jeeps. My first jeep was the 2002 Overland in Silver Metallic, I remember it vividly as it was when the Overland model was brand-spankin-new, and the 4.7HO was considered on par with the previous 5.9 Magnum Jeep. One of the primary reasons I liked the Jeep was it's "Quadra-Drive" System, which boasted the "gerator" couplings in both differentials and the new center differential , aka transfer case.
As the years went on I sold that jeep but I think "Quadra-Drive II" came out, which I suppose was an improvement. I was always under the impression that the Jeeps had an advanced locking 4WD system that could distribute power to any of the wheels, as much as 100% to the one wheel that had traction if needed.
So am I now to find out that this isn't the case, that we have a STUPID transfer case that does nothing more than send 50/50 torque to OPEN differentails? When did this happen and why do we have such an archaic system in our 2006+ model jeeps?
If we do have open diffs, then why not just throw a locker in the rear. A Dana44 isn't exactly the re-invented wheel... there must be a dozen different lockers availablel for it, pneumatic, mechanical, or electrical.
