wheel wrench to tighten the nuts until the wheel
is held against the hub.
11. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
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 5-102 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 5-102 for the wheel nut
torque specification.

reinstall the center cap. Place the cap on the wheel
and tap it into place until it sits flush with the wheel.
12. Tighten the nuts firmly
in a crisscross
sequence as shown by
turning the wheel
wrench clockwise.
