I have a 2011 4 door jeep wrangler X 4x4.
A few months ago I went ahead and got it lifted.
I took to a local off road shop and got a 4" lift, shock boots, stabilizers and a set of grab handle alignments and this all includes labor for a $1000.
Ever since then every time I hit a bump in the road or drive on a rough patch of road or begins to shake.... And violently. I took it back and they tightened the stabilizer bar, check the reparations and balance and even put in new brake calibers. It still shakes and rattle. I have no clue on why it is doing this and I regret getting the lift.

If anyone can chime in please let me know.

 

Keep taking it back to them until they get it right. If it wasn't shaking before the lift then it is something they didn't torque down enough. I suggest watching the death wobble video by plan man . Maybe you can figure it out since the shop can't. I would also suggest finding a more experienced shop.
