Vibration in front and now I put a 2" BB lift on my 2003 Jeep grand Cherokee and the steering wheel shakes if I hit the brakes hard. I've replaced pads and rotors 3 times since 2006 in front.
I bet your front end alignment was thrown off by the lift. Get a front end alignment and balance your tires. Warped rotors would make the brake pedal pulse but not necessarily make the steering wheel shake.
