WINDNOISE REPAIR

Windnoise leak repairs are very similar to waterleak re-
pairs. Refer to Section 9I, Waterleaks. The actual proce-
dure depends on the type of seal being repaired.

Leaks around the door opening weatherstrips do not al-
ways indicate a faulty weatherstrip. A door or window ad-
justment may resolve the condition. Refer to Section 9P,
Doors or Section 9L, Glass and Mirrors.

DIAGNOSIS

WHEEL RUNOUT

Measure wheel runout with an accurate dial indicator.
Measurements may be taken with the wheels either on or
off the vehicle, using an accurate mounting surface such
as a wheel balancer. Measurements may be taken with or
without the tire mounted on the wheel.

Measure radial runout and lateral runout on both the in-
board and the outboard rim flanges. With the dial indicator
firmly seated next to the wheel and tire assembly, slowly
rotate the wheel one revolution and record the indicator
reading. If any measurement exceeds the following speci-
fications and there is a vibration that wheel balancing will
not correct, replace the wheel. Disregard any indicator
readings due to welds, paint runs, or scratches.

Steel Wheels

S

Radial runout: 0.8 mm (0.03 inch).

S

Lateral runout: 1.0 mm (0.04 inch).

Alloy Wheels

S

Radial runout: 0.8 mm (0.03 inch).

S

Lateral runout: 0.8 mm (0.03 inch)

Measure free radial runout on the center of the tire tread.
The tread can be taped to present a smooth surface. Mea-
sure free lateral runout on the outboard side of the tire
nearest to the tread.

Steel and Alloy Wheels

S

Free radial runout: 1.5 mm (0.06 inch).

S

Free lateral runout: 1.5 mm (0.06 inch).

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.

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
4. Remove the wheel. Difficulty in removing the

wheels from the vehicle can be due to foreign ma-
terial or to a tight fit between the wheel centerhole
and the hub or the rotor. The wheels can be re-
moved using the following procedure:
1) Retightening the wheel blots on the affected

wheel and then loosening the wheel nuts by two
turns.

2) Lowering the vehicle and rocking it from side to

side as hard as possible, using one or more per-
son

’

s body weight to loosen the wheel.

3) 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) Penetrating oil in this area could cause the
wheel to loosen as the vehicle is driven, resulting in
loss of control and an 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.
