Give us a little more insight into your shake/wobble. Is it at a certain speed, or maybe after hitting bumps? How is your alignment and steering components?
Sometimes something as simple as a tire being out of balance can cause wobbles.
Sorry for the late follow-up, like i said bought the jeep about 2 months ago , I replaced wheel bearings, installed RC tie rod and new ends , new drag link, steering stabilizer, 2 weeks ago. Bought new tires and got them balanced at discount tire a week ago , today I installed 4 new RC lower control arms and RC adjustable trac bar as Jeep previously had the stock trac barn installed, drove after the control arms and trac bar insatll and still shaking but obviously very out of alignment, i will take it for alignment tomorrow, hopefully it will help but i dont have my hopes up as the shaking was completely still there. Shaking starts as about 65mph
