When Using Floor Jack
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 axle housing
(1) or rear axle housing (2).
To perform service with either front or rear vehicle end jacked up,
be sure to place safety stands (1) under chassis frame so that
body is securely supported. And then check to ensure that chas-
sis frame does not slide on safety stands (1) and the vehicle is
held stable for safety’s sake. WARNING:
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.
CAUTION:
Never apply jack against suspension parts (i.e., stabi-
lizer, etc.) or vehicle floor, or it may get deformed.

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.
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
bearings.

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, driv-
ing habits, improper alignment.
If the following conditions are noted rotation is in order:
Front tire wear is different from rear.
Uneven wear exists across the tread of any tire.
Left front and right front tire wear is unequal.
Left rear and right rear tire wear is unequal.
There is cupping, flat spotting, etc.
A wheel alignment check is in order if the following conditions are
noted:
Left front and right front tire wear is unequal.
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
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 inch) wide bands when the tire tread depth
becomes 1.6 mm (0.063 inch). 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
vehicle. It is caused by the steel belt not being straight within the
tire. It is most noticeable at low speed, 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 “waddle”. 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, 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 vehi-
cle. Waddle can be quickly diagnosed by using a Tire Problem
Detector (TPD) and following the equipment manufacturer’s rec-
ommendations.
If a TPD is not available, the more time consuming method of sub-
stituting known good tire / wheel assemblies on the problem vehi-
cle can be used as follows:
[A] : Hard cornering, under inflation or lack of tire rotation
[B] : Incorrect wheel alignment, tire construction not uniform or wheel heavy acceleration

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 wadding end of
vehicle. If wadding 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.
