10. Turn the wheel wrench
counterclockwise to lower the
vehicle. Lower the jack
completely.
11. Tighten the nuts firmly in a
crisscross sequence as shown
by turning the wheel wrench
clockwise.
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. See
original equipment wheel nut
torque specifications.
When reinstalling the regular wheel
and tire, also reinstall either the
center cap or the bolt-on hub cap,
depending on which one the
vehicle has.
For center caps, line up the tab
on the center cap with the slot in
the wheel. The cap only goes in
one way. Place the cap on the
wheel and press until it snaps
into place.
For bolt-on hub caps, line up the
plastic nut caps with the wheel
nuts and tighten clockwise by
for
hand to get them started. Then
tighten with the wheel wrench
until snug.
