| installed them? Just throwing a rotor on the front will hardly ever be 100% true. You usually have to index them to find the least amount of runout. I always: Clean hub of any and all rust, dirt or paint. Install rotor, torque lug nuts (all 5) and measure runout Try in it all 5 positions to find the least amount of runout and mark the stud and put a matching mark on the rotor so if you have to remove in the future you will know where it goes. If you have runout in a rotor the vibration will continue to get worse as the miles are put on them, Any time there is runout in the rotor the pad hits that spot on every revolution wearing the rotor unevenly.
