{CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See Capacities and Specifications on page 5-99 for wheel nut torque specification. 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 5-99 for the wheel nut torque specification. 10. Use the wheel wrench to tighten the nuts firmly. Turn the wheel wrench clockwise and in a crisscross sequence as shown. 11. Put the wheel cover or the center cap and plastic wheel nut caps back on. Remove any wheel blocks. 5-79
