The wander is generally incorrect caster, or worn steering components. Got nothing to do with the stance of the jeep.
I didn't mean to finish in the middle, but I had to go (this was at work).
I've adjusted down the ACOS to make it level by using a level on the fender and rear window sill. I didn't use the rocker as it's a bit bubbly (rusty underneath).
As for the wander, I'm not sure if the rear is not aligned with the front and was wondering if this could lead to the Jeep wander? I'm also thinking it could be the steering box itself. When I lower, I adjust the track arm to get as close to making both tires even on the fenders, and adjust the steering to re-center the steering wheel. I don't check the toe or caster. Think lowering it ~3/4-1" is significant to the caster? As for steering components, I do have a new Currie tie rod set to throw on. Just need to get new boots for the ripped ones.
Thanks.
