I have the same setup (2012 with 35" tires and 2.5" lift). I had less than 25,000 miles on it and everything was tight and i would experience the steering wheel wobble (start of death wobble). I cured the problem by increasing the caster using front control arm drop brackets (JKS brand). The factory caster setting is suppose to be 3.7 to 4.7 degrees, but my lift decreased the caster to 2.4 degrees. After installing the control arm drop brackets my caster increased to 5.4 degrees. You can also install adjustable control arms so that you can adjust the caster, but it costs much more than drop brackets. The drop brackets also provide an additional benefit of restoring the angle of the control arms (restore to approximately level) which gives a smoother stock ride over bumps in the road (forces better directed into springs instead of being transmitted directly thru the angled control arms to the frame).
