My symptoms weren't as bad as yours, but I too had a shimmy after hitting a bump in a turn and taking the stabilizer back to stock did the trick. Wasn't anything close to a death wobble though... Good luck 😬
Dumbass of the day here, including this sticker on the back of their trashed Renegade.
Mainly because it also includes this sticker below…
I have to say, I agree with them 😂
My left front spring was bowed towards the sway bar link after a while on the 2.5" lift as well - so much so that it rubbed it under articulation even. New adjustable control arms to fix the caster did the trick.
I do have a JK though in which there isn't any spring isolators - check what...
