That he pulled it off on a YJ is pretty cool - holy crap you can put coil springs, e-lockers and now an e-disconnect sway bar on those old things. And the price for the assembly, at least when he did it, was pretty great - 80 bucks. Heck for 80 bucks, I'd have given the lazy a$% routine a try myself
But, with Jeeps, you've gotta get out to air-down anyway. You might as well pull the pins on the disconnects and lock the manual hubs - if you have them - while your out there; same with airing back up and reconnecting. And it doesn't appear to have been bullet-proof reliable for the guy, either. It looks like he ended up pulling the bar's motor out - scary.
