11. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
CAUTION:
{
Incorrect or improperly tightened wheel nuts
can cause the wheel to come loose and
even come off. This could lead to a crash.
If you have to replace them, be sure to
get new 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 5-133 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 5-133 for the wheel nut
torque specification.
12. Tighten the nuts firmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
When you reinstall the regular wheel and tire, you must
also reinstall either the center cap, or bolt-on hub
cap, depending on what your vehicle is equipped with.
For center caps, place the cap on the wheel and
tap it into place until it seats flush with the wheel.
The cap only goes on one way. Be sure to line up the
tab on the center cap with the indentation on the wheel.
For bolt-on hub caps, align the plastic nut caps with
the wheel nuts and then tighten by hand. Then use the
wheel wrench to tighten.
