Tire and Wheel Removal and Installation
(Wheel Removal)
Caution: If penetrating oil gets on the vertical
surfaces between the wheel and the rotor or drum,
it could cause the wheel to work loose as the
vehicle is driven, resulting in
a
loss of control and
an injury accident.
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 torque specification.
Notice:
NEVER use heat to loosen a tight wheel. It
can shorten the life of the wheel, wheel nuts and wheel
bearings. Excessive force, such as hammering the
wheel or tire, can also cause damage and is not
recommended. Slight tapping of the tire side wall, such
as with one's hand or a rubber mallet, is normally
acceptable.
Important: Penetrating oil has not been found to be
effective in removing tight wheels. However, if
used, you should apply the oil sparingly on the wheel
centerhole area only.
Sometimes the wheels can be difficult to remove due
to foreign material or a tight fit between the wheel
centerhole and the rotor.
You can remove the wheel without damage through
the following steps:
1. Retighten all the wheel nuts on the affected
wheel. Then loosen each nut two turns. Rock
the vehicle from side to side. If this is not effective,
go to step 2.
2. Rock the vehicle from Drive and Reverse allowing
the vehicle to move several feet in each direction.
Apply quick, hard pressure on the brake pedal in
order to loosen the wheel. If the wheel still does not
loosen, then rock the vehicle again from side to
side as hard as possible using one or more
person's body weight. If the wheel is still tight,
repeat the procedure.
