If you have more death wobble, check those ball joints. They can wear out pretty quick on JK's. Especially if it was driven 60k miles at 44 psi. I would also recommend getting some Adjustable lower control arms for the front. The 2 doors drive great when stock, but when they are lifted, they get squirrely as shit unless you keep that caster dead on.
Teraflex Alpine arms made a huge difference in mine after lifting it.
