When I bought this Jeep 4 months ago it had 35's and I don't remember any vibes. Now that I am doing all of this suspension work and now on 33's is vibes. I'm reading now that 4.88 gears and 33s is a vibrating combo? The only other thing I realized is, it has a stock front track-bar on the 4" lift. Maybe I need a front track-bar and upper adjustable arms to help dial shit in.
