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.

TIRE DIAGNOSIS
IRREGULAR AND/OR PREMATURE WEAR
Irregular and premature wear has many causes. Some of them
are: incorrect inflation pressures, lack of tire rotation, driving hab-
its, improper alignment.
If the following conditions are noted, rotation is necessary:
Front tire wear is different from rear.
Uneven wear exists across the tread of any tire.
Front tire wear is unequal between the right and left.
Rear tire wear is unequal between the right and left.
There is cupping, flat spotting, etc.
A wheel alignment check is necessary if following conditions are
noted:
Front tire wear is unequal between the right and left.
Wear is uneven across the tread of any front tire.
Front tire treads have scuffed appearance with “feather”
edges on one side of tread ribs or blocks.
WEAR INDICATORS
Original equipment tires have built-in tread wear indicators (1) to
show when they need replacement.
These indicators (1) 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 (1) appear in 3 or more grooves at 6 loca-
tions, tire replacement is recommended.NOTE:
*1: Right-to-left trim height (“H”) difference should be
within 15 mm (0.6 in.) with curb weight. (same with rear
side.)
“H”
[A] : Hard Cornering, under inflation or lack of tire rotation
[B] : Incorrect wheel alignment, tire construction not uniform or wheel heavy acceleration

RADIAL TIRE WADDLE
Waddle is side to side movement at the front and/or rear of the
vehicle. It is caused by the steel belt not being straight within the
tire. It is most noticeable at a low speed, 8 to 48 kph (5 to 30
mph).
It is possible to locate the faulty tire by road testing the vehicle. If
it is on the rear, the rear end of the vehicle shakes from side to
side or “waddles”. To the driver in the seat, it feels as though
someone is pushing on the side of vehicle.
If the faulty tire is on the front, waddling 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 vehicle.
Waddle can be quickly diagnosed by using Tire Problem Detector
(TPD) and following the equipment manufacture’s recommenda-
tions.
If TPD is not available, an alternative method of substituting
known-good tire/wheel assemblies can be used as follows,
although it takes a longer time.
1) Ride vehicle to determine whether the front or rear waddles.
2) Install tires and wheels that are known to be good (on similar vehicle) in place of those on waddling end of
vehicle. If waddling end cannot be identified, substitute rear ones.
3) Road test again. If improvement is noted, reinstall originals one at a time till waddle causal tire is found. If no
improvement is noted, install known-good tires in place of all four. Then reinstall originals in the same man-
ner as above.
EQUIPMENT MANUFACTURE’S RECOMMENDATIONS
In flate tires to recommended pressure
Road test vehicle on level unrowned road in both directions
Switch front tires side to side and road test again
Lead corrected,
if roughness results, replace tiresLeads in same directionLeads reverses direction
Put tires back in original position
and check alignmentInstall a known-good tire on one front side
Lead remains install a known-good
tire in place of other front tire
Lead remains known-good tires are not goodLead corrected replace tire
Lead corrected replace tire

STEERING, SUSPENSION, WHEELS AND TIRES 3-7
RADIAL TIRE LEAD
“Lead” is the deviation of the vehicle from a straight path on a level rod even with no pressure on the steering
wheel.
Lead is usually caused by:
Incorrect alignment.
Uneven brake adjustment.
Tire construction.
The way in which a tire is built can produce lead in a vehicle. An example 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 has a little larger diameter than the other, the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in above figure (Lead Diagnosis) should be used to make sure that front alignment is not mis-
taken for tire lead.
Part of the lead diagnosis procedure is different from the proper tire rotation pattern currently in the owner
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
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, its possible causes are as follows.
Tire runout.
Wheel runout.
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 TPD is not available, alternative
method of substituting known-good tire and wheel assemblies on the problem vehicle can be used, although it
takes a longer time.
[A] : Tire out of round 1. Smooth road
[B] : Tire stiffness variation 2. Suspension movement (loaded runout)
[C] : Rim bent or out of round
