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:

1. Ride vehicle to determine if the waddle is coming from the front
or rear.
2. Install tires and wheels that are known to be good (on similar ve-
hicle) in place of those on the offending end of the vehicle. If the
waddle cannot be isolated to front or rear, substitute the rears.
3. Road test again. If improvement is noted, install originals one at
a time until offender is found. If no improvement is noted, install
known good tires in place of all four. Then install originals one
at a time until offender if found.

RADIAL TIRE LEAD
ªLeadº is the deviation of the vehicle from a straight path on a level
road with no pressure on the steering wheel.
Lead is usually caused by:
1) Incorrect alignment.
2) Uneven brake adjustment.
3) Tire construction.
The way in which a tire is built can produce lead in a vehicle. An ex-
ample of this is placement of the belt. Off center belts on radial tires
can cause the tire to develop a side force while rolling straight down
the road. If one side of the tire is a little larger diameter than the oth-
er, the tire will tend to roll to one side. This will develop a side force
which can produce vehicle lead.
The procedure on previous page should be used to make sure that
front alignment is not mistaken for tire lead.
1) Part of the lead diagnosis procedure is different from the tire
rotation pattern currently in the owner's and service manuals. If
a medium to high mileage tire is moved to the other side of the
vehicle, be sure to check that ride roughness has not developed.
2) Rear tires will not cause lead.
VIBRATION DIAGNOSIS
Wheel unbalance causes most of the highway speed vibration
problems. If a vibration remains after dynamic balancing, it can be
caused by three things.
1) Tire runout.
2) Wheel runout.
3) Tire stiffness variation.
Measuring tire and / or wheel free runout will uncover only part of the
problem. All three causes, known as loaded radial runout, must be
checked by using a Tire Problem Detector (TPD). If a TPD is not
available, the more time consuming method of substituting known
good tire and wheel assemblies on the problem vehicle can be
used.

NOTE:

All suspension fasteners are an important attaching part in that it could affect the performance of vital
parts and systems, and / or could result in major repair expense. They must be replaced with one of the
same part number or with an equivalent part if replacement becomes necessary. Do not use a replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly to assure proper retention of this part.

Never attempt to heat, quench or straighten any suspension part. Replace it with a new part, or damage
to the part may result.

3E-2 REAR SUSPENSION
GENERAL DESCRIPTION
Rear suspension is 5 link type of rigid axle which consists of coil springs, rear axle, shock absorbers, upper rods,
lower rods and lateral rod.
The lower rod and upper rod are connected with the axle and body by using bushes so that axle moves up and
down with bushes as their supporting points.
The shock absorber is installed between the body and axle to absorb up-and-down movement of the vehicle body.
