3-2 STEERING, SUSPENSION, WHEELS AND TIRES
DIAGNOSIS
GENERAL DIAGNOSIS
Since the problems in steering, suspension, wheels and tires involve several systems, they must all be consid-
ered when diagnosing a complaint. To avoid using the wrong symptom, always road test the vehicle first. Pro-
ceed with the following preliminary inspection and correct any defects which are found.
1) Inspect tires for proper pressure and uneven wear.
2) Raise vehicle on a hoist and inspect front and rear suspension and steering system for loose or damaged
parts.
3) Spin front wheels. Inspect for out-of-round tires, out-of-balance tires, bent rims, loosen and/or rough wheel
bearings.

WHEELS AND TIRES 3F-5
MAINTENANCE AND MINOR ADJUSTMENTS
WHEEL MAINTENANCE
Wheel repairs that use welding, heating, or peening are not approved. All damaged wheels should be replaced.
WHEEL ATTACHING STUDS
If a broken stud is found, see Section 3E (rear) or Section 3D (front) for Note and Replacement procedure.
MATCHED TIRES AND WHEELS
Tires and wheels are match mounted at the assembly plant.
This means that the radially stiffest part of the tire, or “high spot”,
is matched to the smallest radius or “low spot” of the wheel.
This is done to provide the smoothest possible ride.
The “high spot” of the tire is originally marked by paint dot (1) on
the outboard sidewall. This paint dot will eventually wash off the
tire.
The “ow spot” of the wheel is originally marked by paint dot (2) on
the wheel rim-flange. Properly assembled, the wheel rims’ paint
dot should be aligned with the tires’ paint dot as shown in left fig-
ure.
Whenever a tire is dismounted from its wheel, it should be
remounted so that the tire and wheel are matched. If the tire’s
paint dot cannot be located, a line should be scribed on the tire
and wheel before dismounting to assure that it is remounted in
the same position.
TIRE MAINTENANCE
TIRE PLACARD
The “Tire Placard” is located on the left door (right door for right-hand side steering vehicle) lock pillar and
should be referred to tire information.
The placard lists the maximum load, tire size and cold tire pressure where applicable.
NOTE:
Whether rim size and/or maximum load are listed or not depends on regulations of each country.
