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 422
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 422 for
the wheel nut torque specification.
12. Tighten the nuts
firmly in a crisscross
sequence as
shown by turning
the wheel wrench
clockwise.
