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.
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 for

for

crisscross sequence, as
shown, by turning the wheel
wrench clockwise.
For vehicles with dual wheels, have
a technician check the wheel nut
tightness of all wheels with a torque
wrench after the first 160 km
(100 mi) and then 1 600 km
(1,000 mi) after that. Repeat this
service whenever you have a tire
removed or serviced. See
.
When reinstalling the regular wheel
and tire, also reinstall either the
center cap, or bolt-on hub cap,
depending on what the 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.
