{ CAUTION: Wheel nuts that are improperly or incorrectly tightened can cause the wheels to become loose or come off. The wheel nuts should be tightened with a torque wrench to the proper torque specification after replacing. Follow the torque specification supplied by the aftermarket manufacturer when using accessory locking wheel nuts. See Capacities and Specifications on page 5-114 for original equipment wheel nut torque specifications. 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. See Capacities and Specifications on page 5-114 for the wheel nut torque specification. 11. Use the wheel wrench to tighten the nuts firmly. Turn the wheel wrench clockwise and in a crisscross sequence as shown. 12. Put the wheel cover or the center cap and plastic wheel nut caps back on. Remove any wheel blocks. Have a technician check the wheel nut tightness of all wheels with a torque wrench after the first 100 miles (160 km) and then 1,000 miles (1600 km) after that. Repeat this service whenever you have a tire removed or serviced. See Capacities and Specifications on page 5-114 for more information. 5-93
