3-8 STEERING, SUSPENSION, WHEELS AND TIRES
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.

GENERAL INFORMATION
Front alignment refers to the angular relationship between the front wheels, the front suspension attaching parts
and the ground. Generally, the only adjustment required for front alignment is toe setting.
Camber and caster can't be adjusted. Therefore, should camber or caster be out of specification due to the damage
caused by hazardous road conditions or collision, whether the damage is in body or in suspension should be deter-
mined. If the body is damaged, it should be repaired and if suspension is damaged, it should replaced.
TOE SETTING
Toe is the turning in or out of the front wheels. The purpose of a toe specification is to ensure parallel rolling of the
front wheels (Excessive toe-in or toe-out may increase tire wear).
Amount of toe can be obtained by subtracting ªAº front ªBº as shown in above figure and therefore is given in mm
(in.).

POWER STEERING (P/S) SYSTEM
WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
Some parts in the Power Steering Gear Box cannot be disassembled or adjusted. For detailed informa-
tion, refer to the description of ªPOWER STEERING GEAR BOX ASSEMBLYº.
All steering gear fasteners are important attaching parts in that they 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 these parts.
Although the figures in this section show only the left-hand steering vehicle, the same work procedure
and data apply to the right-hand steering vehicle.

oughly, disconnect hose from pump and install special tool (oil
pressure gauge, attachment and hose).
Tighten each flare nut to specified torque.
CAUTION:
Take care not to cause damage to A / C condenser during
service operation, if equipped.

(B): 09915-77420
2) Check each connection for fluid leakage and bleed air.
Refer to ªAIR BLEEDING PROCEDUREº in this section.
3) With engine idling, turn steering wheel and warm up engine till
temperature of fluid in P/S fluid reservoir rises to 50 ± 60C (122
± 140F).
4) Check back pressure by measuring hydraulic pressure with en-
gine idling and hands off steering wheel.
Back pressure: Lower than 1000 kPa (10 kg / cm
2, 142 psi)
When back pressure is higher than specified values, check con-
trol valve and piping for clogging.

knuckle, set rack in position close to neutral. Then obtain the neu-
tral state by aligning match marks on pinion shaft and steering
gear case and insert steering lower joint into pinion shaft.
CAUTION:
Be sure to confirm that steering wheel and front tires
(wheels) are in straight position when inserting steering
lower joint into steering pinion shaft.

CAUTION:
Never disassemble tie-rod except for canvas top LH model.
Performing this prohibited service will affect original per-
formance.
1) Remove steering gear box by referring to ªPOWER STEERING
GEAR BOX ASSEMBLY REMOVALº in this section.
2) For ease of adjustment after installation, make marking of tie-rod
end lock nut position of tie-rod end thread.
3) Loosen tie-rod end lock nut and remove tie-rod end.
4) Remove boot wire and clip.
5) Remove boot from tie-rod.
INSTALLATION
1) Visually inspect that rack and rack end ball joint are free from dirt
or foreign matters. Clean thoroughly with cloth or such.
Position boot properly in grooves of gear case and tie-rod and
clamp it with wire and clip.
Wire should be new and should go around twice.
Pull its both ends together by screw driver or such and make
sure that the wire won't be crossed. Then twist the ends several
times, the twisted ends should be bent in the circumferential
direction.
After this, check to ensure that wire is tight and boot is free from
twist and dent.
