Tighten the nuts firmly in a crisscross sequence as shown by turning the wheel wrench clockwise. NOTICE: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. 5-30
