another question from someone who is trying to understand this whole thing. would having adjustable controle arms help to reduce the chance of this happening or not make a difference.
and just to help me sleep better, with a 2.5 coil lift, stock gears and DS's i am in the clear for this happening. i Know i meet none of the post 16 requirements but just want to ask in case.

Your mostly stock components are reducing your chances of this happening.

This brings me to another point.
The owner's manual says not to tow the JK on a front wheel dolly because it will cause t-case damage.
Having the front hubs unlocked, and the front drive line not rotating, should be identical to having the front wheels on a dolly.
I called the vender who sells the hubs and asked about this. They said the front drive shaft still spins, although not as fast as if the hubs were connected.
I then pm'd a forum member who has the hubs. He said the front drive shaft does not spin when driving with the hubs disconnected.
That facet of the problem is still in question.
Chrysler doesn't make the t-case.

This is the recipe for disaster:
Lifted
Regeared
After market front drive shaft with single joint at the pinion, double cardan at the t-case
An adapter at the t-case that increases the distance of the double cardan from the t-case.
Front pinion more than a few degrees out of alignment with the drive shaft
Highway speed
That's when you are tooling along, fat, dumb, and happy, (no offense, it's just an expression), then you suddenly hear the onset of vibration. Then, all of a sudden, KABOOM!
It's happened to quite a few JKers.
The thing that would prevent this is getting the front pinion and drive shaft into alignment. The double cardan at the t-case requires the front joint to be in alignment with the drive shaft.
But then, that can't be done on a lifted JK because you would have too little caster.

You must have had something else going on, as your front drive shaft should not have been spinning. Some t-cases have exploded from lack of lubication of the front output area.
This brings me to another point.

I have the Tom woods double double cardan drive shaft in the front of my jk. It seems to be doing fine, also not sloppy at all, when both ends are bolted up u can not even move the driveshaft at all.
