Removal Procedure
1. Loosen the wheel bolts.
2. Raise and suitably support the vehicle.
3. Remove the wheel bolts.
Notice : Never use heat to loosen a tight wheel. It can
shorten the life of the wheel, the wheel nuts and the wheel
bearings. Excessive force, such as hammering the wheel
or tire, can also cause damage and is not recommended.
Slight tapping of the wheel sidewall with one’s hand or with
a rubber mallet is acceptable.
4. Remove the wheel.
Difficulty in removing the wheels from the vehicle can be
due to foreign material or to a tight fit between the wheel
centerhole and the hub or the rotor. These wheels can be
removed by
5. Retightening the wheel bolts on the affected wheel
and then loosening the wheel bolts by two turns.
6. Lowering the vehicle and rocking it from side to side
as hard as possible, using one or more person’s
body weight to loosen the wheel.
7. Raising the vehicle and removing the wheel.
CAUTION : Do not allow the penetrating oil to get on
the vertical surfaces between the wheel and the drum
(or rotor) because penetrating oil in this area could
cause the wheel to work loose as the vehicle is driven,
resulting in loss of control and an injury accident.
Penetrating oil is not effective in removing tight wheels. If
it is used, however, apply it sparingly and only to the
wheel’s centerhole area.
Installation Procedure
Notice : Before installing the wheels, remove any buildup
of corrosion on the wheel mounting surface and the brake
drum or the rotor mounting surface by scraping and brush-
ing them with a wire brush. Installing the wheels without
good metal–to–metal contact at the mounting surfaces
can cause the wheel nuts to loosen, which can later allow
a wheel to come off while the vehicle is moving. Wheel
bolts must be tightened in sequence and to the proper
torque to avoid bending the wheel, the brake drum or the
rotor.
1. Mount the wheel.
2. Install the wheel bolts in the sequence shown. Do
not tighten the wheel bolts.
3. Lower the vehicle.
Tighten
Tighten the wheel bolts to 100 NSm (74 lb–ft).

ALLOY WHEEL POROSITY
Wheel repairs that use welding, heating or peening are not
approved.
1. Raise and suitably support the vehicle.
2. Remove the wheel. Refer to ”Wheel” in this sec-
tion.
CAUTION : To avoid serious injury, do not stand over
the tire when inflating, because the bead may break
when it snaps over the safety hump. Do not exceed
275 kPa (40 psi) of air pressure in any tire if the beads
are not seated. If 275 kPa (40 psi) of air pressure will
not seat the beads, deflate the tire. Relubricate the
beads. Reinflate the tire. Overinflation may cause the
bead to break and cause serious injury.
3. Locate leaking areas by inflating the tire to 345 kPa
(50 psi) and dipping the tire and wheel assembly
into a water bath.
4. Mark the leak areas and remove the tire from the
wheel.
5. Scuff the inside wheel surface at the leak area with
80–grit sandpaper. Clean the leak area with a gen-
eral–purpose cleaner.
6. Apply a 3.3 mm (0.13 inch) thick layer of adhesive/
sealant to the leak area. Allow it to dry for 12 hours.
7. Install the tire on the wheel. Inflate the tire to 345
kPa (50 psi) and check for leaks as in step 3.
8. Adjust the tire pressure to meet specifications. Re-
fer to ”Tire Size and Pressure Specifications” in
this section.
9. Balance the wheel. Refer to ”Tire and Wheel Bal-
ancing” in this section.
10. Install the wheel. Refer to ”Wheel” in this section.
11. Lower the vehicle.
ALLOY WHEEL REFINISHING
A protective clear or color coating is applied to the surface
of the original equipment cast alloy wheels. Surface deg-
radation can develop if this clear coating is damaged or re-
moved. This can happen at some automatic car wash fa-
cilities that use silicon carbide–tipped tire brushes to clean
white walls and tires. Once the protective coating is dam-
aged, exposure to caustic cleaners or road salt causes fur-
ther surface degradation. The following procedure details
how to strip, clean and recoat alloy wheels.
CAUTION : To avoid serious personal injury, follow
the manufacturer’s recommendations and cautions
when using these materials.
Required materials:

equivalent cleaning and conditioning chemical for
alloys.
