Doesn’t the Wrangler have live axles? 
Yes, is that surprising?
Yeah Ian said its probably going to have to be done by a mechanic unless you have the certain type of tools it requires
Yes, because since the wheels are rigidly connected with the axle, a sway bar is not needed.
Why would you think a sway bar is not needed? A live axle couples left and right camber, but a sway bar is still needed to couple the left and right vertical excursions.
Live axles need a sway bar MORE than independent suspension.
Because the suspension is inboard of the wheel (coil or leaf, it matters not) the increased weighting of the outboard wheel increases the weight on the inboard wheel, which exacerbates body roll. This decreases stability at speed, but helps articulation off-road.
There is a small grain of truth to Dog80’s post. Leaf springs on a Hotchkiss drive resist roll as well as compression. A swaybar is beneficial but not as vital as they are on a coil spring suspension. Most trucks with leaf spring rear suspension do not have them from the factory. Maybe in the days when Mustangs had leaf springs, it was more common, but modern vehicles that use leaf springs are usually not deisgned for agile handling anyway.
Presumably Fubaya’s Wrangler has coil springs.
