Take it out and see of theres vibes. If not then your good and a mml will still be fine. If so, wait til the mml goes on and see if it rids of them. If it doesnt then add washers inbetween until they are gone. With a 3 inch suspension lift and 1.25 body lift my jeep only needed 4 washers to rid of vibes
