0A-20 GENERAL INFORMATION
In raising front or rear vehicle end off the floor by jacking, be sure
to put the jack against the center portion of the front suspension
frame or rear axle housing.
WARNING:
Never apply jack against suspension parts (i.e., stabilizer,
etc.) or vehicle floor, or it may get deformed.
If the vehicle to be jacked up only at the front or rear end,
be sure to block the wheels on ground in order to ensure
safety.
After the vehicle is jacked up, be sure to support it on
stands. It is extremely dangerous to do any work on the
vehicle raised on jack alone.
To perform service with either front or rear vehicle end jacked up,
be sure to place safety stands under chassis frame so that body is
securely supported. And then check to ensure that chassis frame
does not slide on safety stands and the vehicle is held stable for
safety's sake.

CONTENTS
GENERAL DIAGNOSIS
Since the problems in steering, suspension, wheels and tires involve several systems, they must all be considered
when diagnosing a complaint. To avoid using the wrong symptom, always road test the vehicle first.
Proceed with the following preliminary inspections 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 wheel. Inspect for out-of-round tires, out-of-balance tires, bent rims, loose and / or rough wheel bear-
ings.

TIRE DIAGNOSIS
IRREGULAR AND / OR PREMATURE WEAR
Irregular and premature wear has many possible causes. Some of
them are: incorrect inflation pressures, lack of tire rotation, driving
habits, improper alignment.
If the following conditions are noted, rotation is in order:
1. Front tire wear is different from rear.
2. Uneven wear exists across the tread of any tire.
3. Left front and right front tire wear is unequal.
4. Left rear and right rear tire wear is unequal.
5. There is cupping, flat spotting, etc.
A wheel alignment check is in order if the following conditions are
noted:
1. Left front and right front tire wear is unequal.
2. Wear is uneven across the tread of any front tire.
3. Front tire treads have scuffed appearance with ªfeatherº edges
on one side of tread ribs or blocks.
WEAR INDICATOR
The original equipment tires have built-in tread wear indicators to
show when tires need replacement. These indicators will appear as
12 mm (0.47 in.) wide bands when the tire tread depth becomes 1.6
mm (0.063 in.). When the indicators appear in 3 or more grooves
at 6 locations, tire replacement is recommended.
RADIAL TIRE WADDLE
Waddle is side to side movement at the front and / or rear of the ve-
hicle. It is caused by the steel belt not being straight within the tire.
It is most noticeable at low speed, 8 to 48 km / h (5 to 30 mph). It is
possible to road test a vehicle and tell on which end of the vehicle
the faulty tire is located. If the waddle tire is on the rear, the rear end
of the vehicle will shake from side to side or ªwaddleº. From the driv-
er's seat it feels as though someone is pushing on the side of the
vehicle. If the faulty tire is on the front, the waddle is more visual.
The front sheet metal appears to be moving back and forth and the
driver feels as though he is at the pivot point in the vehicle.
Waddle can be quickly diagnosed by using a Tire Problem Detector
(TPD) and following the equipment manufacturer's recommenda-
tions.
If a TPD is not available, the more time consuming method of sub-
stituting known good tire / wheel assemblies on the problem vehicle
can be used as follows:
