cause an accident. When you change a wheel,
remove any rust or dirt from places where the
wheel attaches to the vehicle. In an emergency,
you can use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt off.

nuts tightened with a torque wrench to the
proper torque specication. SeeCapacities
and Specifications on page 5-115for wheel
nut torque specication.
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 specication. SeeCapacities
