10. Tighten each wheel nut by hand. Then use the
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 5-100 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 5-100 for the wheel
nut torque specification.
12. Tighten the nuts
firmly in a crisscross
sequence as shown
by turning the wheel
wrench clockwise.
13. When you install the wheel and tire, you must
also reinstall the center cap. Place the cap on
the wheel and tap it into place until it sits flush
with the wheel.
