{ 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 5-116 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 5-116 for the wheel
