DIAGNOSIS
TIRE DIAGNOSIS
Irregular and Premature Wear
Irregular and premature tire wear has many causes. Some
of them are incorrect inflation pressures, lack of regular
rotation, poor driving habits, or improper wheel alignment.
If the wheel alignment is reset because of tire wear, always
reset the toe as close to zero degrees as the specification
allows. Refer to ”Rear Toe Adjustment” in this section.
Rotate the tires if:
S The front tire wear is different from the rear.
S The left and right front tire wear is unequal.
S The left and right rear tire wear is unequal.
Check wheel alignment if:
S The left and right front tire wear is unequal.
S The wear is uneven across the tread of either front
tire.
S The front tire treads are scuffed with ”feather”
edges on the side of the tread ribs or blocks.
Tread Wear Indicators
The original equipment tires have built–in tread wear indi-
cators to show when the tires need replacement. These in-
dicators appear as bands when the tire tread depth be-
comes shallow. Tire replacement is recommended when
the indicators appear in three or more grooves at six loca-
tions.
Radial Tire Waddle
Waddle is side–to–side movement at the front or rear of
the vehicle. It is caused by the steel belt not being straight
within the tire, or by excessive lateral runout of the tire or
wheel. It is most noticeable at low speeds, 8 to 48 km/h (5
to 30 mph), but may appear as ride roughness at 80 to 113
km/h (50 to 70 mph).
The vehicle must be road tested to determine which end
of the vehicle has the faulty tire. The rear end of the vehicle
will shake from side to side or ”waddle” if the waddle tire
is on the rear of the vehicle. From the driver’s seat, it feels
as though someone is pushing on the side of the vehicle.
If the faulty tire is on the front of the vehicle, the waddle is
more visual. The front sheet metal appears to be moving
back and forth, and the driver’s seat feels like the pivot
point in the vehicle.
Waddle can be diagnosed using the method of substi–tut-
ing known good tire and wheel assemblies on the problem
vehicle.
1. Road test the vehicle to determine if the waddle is
coming from the front or the rear of the vehicle.
2. Install good tires and wheels from a similar vehicle
in place of those on the offending end of the prob-
lem vehicle. If the source of the waddle is not ob-
vious, change the rear tires.
3. Road test the vehicle. If there is improvement,
install the original tires to find the offending tire. If
there is no improvement, install good tires in place
of all four offending tires.

PRELIMINARY INSPECTION
ChecksAction
Check the tires for proper inflation pressures and normal
tread wear.Inflate the tires to the proper tire pressure. Replace the
tires as needed.
Check the wheel bearings for looseness.Tighten the axle nut to the proper specification. Replace
the strut wheel bearing as needed.
Check for loose ball joints and tie rod ends.Tighten the ball joints and the tie rods.
Check the runout of the wheels and the tires.Measure and correct the tire runout.
Check the vehicle trim heights.Correct the trim heights. Make the correction before ad-
justing the toe.
Check for loose rack and pinion mounting.Tighten the mounting brackets for the rack and pinion as-
sembly.
Check for improperly operating struts.Replace the strut assembly.
Check for loose control arms.Tighten the control arm attachment bolts. Replace the con-
trol arm bushings as needed.
FRONT TOE ADJUSTMENT
1. Disconnect the outer tie rods from the knuckle as-
semblies. Refer to Section 6C, Power Steering
Gear.
2. Turn the right and the left outer tie rods and the ad-
juster nuts to align the toe to 0.0 ± 0.10 degree.
3. Reconnect the outer tie rods to the knuckle assem-
blies. Refer to Section 6C, Power Steering Gear.
Notice : In this adjustment, the right and the left tie rods
must be equal in length, or the tires will wear unevenly.FRONT CAMBER AND CASTER
CHECK
The front camber and caster are not adjustable. Refer to
”Wheel Alignment Specifications” in this section. Jounce
the bumper three times before measuring the camber or
the caster in order to prevent an incorrect reading. If the
front camber or caster measurements deviate from the
specifications, locate and replace or repair any damaged,
loose, bent, dented, or worn suspension part. If the prob-
lem is body related, repair the body.
REAR CAMBER CHECK
The rear camber is not adjustable. Refer to ”Wheel Align-
ment Specifications” in this section. If the rear camber
deviates from the specification, locate the cause and cor-
rect it. If damaged, loose, bent, dented, or worn suspen-
sion parts are found, they should be repaired or replaced.
If the problem is body related, repair the body.

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: 0.25 mm (0.01 inch)
S Lateral runout: 0.25 mm (0.01 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.

UNIT REPAIR
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:
S Amchem Alumi Prep No. 33. Stock No. DX533 or
equivalent cleaning and conditioning chemical for
alloys.
