What’s this on the JL front axle

It's a front axle disconnect I believe. We were talking about it over on jlwrangler when Eddie and Cindy did the reveal coverage. A few manufacturers have used them over the years.

What I’ve read is, it’s almost like locking hubs. The Long shaft it split in two and spins freely until the actuator is activated and it locks the shaft.

Yes. It's just less power train resistance. I'm guessing fuel economy and lower parts wear would be primary reasons for this.

This ^^^ The FAD or front axle disconnect is designed to act like manual locking hubs in the open position. This is supposed to help improve MPG but at the cost of creating one more weak link. What I can tell you is that the engineers at Jeep fought hard to get rid of this thing.
 
So I guess manual locking hubs are a deal breaker, so it's either live axle or better MPG!
 
So is this a throwback to the beloved CAD system in the YJ's, sort of Jeep's version of the other manufacturers doing their retro styling?
 
here is a pic of the system they are using in the JL

Edit: sorry its upside down.

Unfortunately, yes. But, it is supposed to be an improved version of it.

Chevy and Dodge have been using these in their pickups for a long time. They are usually pretty reliable but I wouldn’t want it on an offroad vehicle.

This is true but like you, I'd prefer not to have another weak link. Even the guys at Jeep fought against having this.
