my 2008 jku starts to shake at 50 mph. it is not like a out of control shake. i can take my hands off the wheel and watch the steering wheel shake back and forth i can feel it shake my body. i recentley installed a 2 inch rancho sport lift. and added a new steering stabilizer. and new sway bar links. the tires were rotate properly also. anyone have a idea what it is. it starts shaking at exactly 50 i slow down and it goes away.
