There is rumors of a “new” gearbox that is supposed to be released by the end of the year that is cast iron like the Jk. The wandering and the dead spot are two different things, my JLUR was absolutely terrible with the wandering. I replaced all the control arms and installed them correctly ( the way I linked earlier) and am running 6.5* caster. I have a very small dead spot 1/2 in only when the outside temp is below 60-65. In warmer weather it’s as tight as a rack system. I have fixed several of these the same way and have also swapped the AE box and corrected the dead spot. Every box is manually set from the supplier and can be set differently. I went through 5 boxes once before getting one that had acceptable play. You can bench test the box prior to installing them and have a pretty good idea if they are good or not prior to installing.DO you know of a fix(or one coming( for this steering issue(dead spot) with you experience, fixed my wandering with adjustable LCA bringing caster over 6.0
Not that I would recommend this but I have actually rented a Jl with good steering and was able to swap the box into a Jl with a decent amount of free play. The poor driving Jeep Drove perfect after the swap. A good majority of the issues with the dead spot absolutely Is the box.
