No idea. The best way to correct issues is to have a known starting point. Anything else is guessing. Now that you have your baseline you can look into options for adding more caster.
Going through this on my 2018.
Dealer installed a leveling kit when I bought it new. Fast forward to recently and local dealer replaced all of my front end joints at 32k. Post repair alignment showed caster of 1.6 and 1.8. Figured I'd try caster bushings now since I've never been happy with the steering feedback.
Bought the SPC 2.3 and 2.6 bushings.
Had a shop install and caster is showing 3.2 and 3.9. I may be off a tenth or so but those numbers stick out. Definitely under 4.
It did help the bumpsteer but I'm fighting a tire balance issue that moves the steering wheel constantly. Getting a road force balance next week.
