remove all wheels from vehicle and install it on the tire balance machine.if it off,install wheel weights.once balance,put it back to the vehicle and put the vehicle on the alignment machine.make sure all tires treads are okay and pressure are inflated corectly.get a reading and see if it under specification.if it not,you can adjust it or replace worn parts to bring it back to specification
