Perhaps.Aren’t the 2021’s also getting cast iron steering knuckles vs the 2018-20 aluminum ones? Sounds like FCA may have gone a little too far trying to save weight on steering components
IIRC, JL weighs 200 lbs less than JK, despite being larger, having a bigger transmission and more “stuff”. They had to remove the weight somehow.
The new, lighter, Dana axles have been holding together well as far as I can tell. Sure hope they keep doing that.
