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:
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 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.
1) 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.
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, its possible causes are as follows.
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 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

Diagnosis

For the details, refer to “Diagnosis Table” in Section 3.
Preliminary Checks Prior To Adjusting Front Wheel Alignment
Steering and vibration complaints are not always the result of improper alignment. An additional item to be
checked is the possibility of tire lead due to worn or improperly manufactured tires. “Lead” is the deviation of the
vehicle from a straight path on a level road without hand pressure on the steering wheel. Section 3 of this man-
ual contains a procedure for determining the presence of a tire lead problem. Before making any adjustment
affecting toe setting, the following checks and inspections should be made to ensure correctness of alignment
readings and alignment adjustments:
1) Check all tires for proper inflation pressures and approximately the same tread wear.
2) Check for loose of king pin bearings. Check tie rod ends; if excessive looseness is noted, it must be cor-
rected before adjusting.
3) Check for run-out of wheels and tires.
4) Check vehicle trim heights; if out of limits and a correction is to be made, it must be made before adjusting
toe.
5) Check for loose of suspension arms.
6) Check for loose or missing stabilizer bar attachments.
7) Consideration must be given to excess loads, such as tool boxes. If this excess load is normally carried in
vehicle, it should remain in vehicle during alignment checks.
8) Consider condition of equipment being used to check alignment and follow manufacturer's instructions.
9) Regardless of equipment used to check alignment, vehicle must be on a level surface both fore and aft and
transversely.
Toe Adjustment
Toe is adjusted by changing tie rod length. Loosen right and left
tie rod end lock nuts first and then rotate tie rod to align toe-in to
specification.
In this adjustment, right and left tie rod should become equal in
length (“A”).
After adjustment, tighten lock nuts to specified torque.
Tightening torque
Tie rod end lock nuts
(a) : 65 N·m (6.5 kg-m, 47.0 lb-ft)

Camber And Caster Check And Adjustment
Should camber or caster be found out of specifications upon
inspection, locate its cause first. If it is in damaged, loose, bent,
dented or worn suspension parts and axle housing, they should
be replaced. If it is in vehicle body, repair it so as to attain specifi-
cations.
Steering Angle Check And Adjustment
When tie rod (2) or tie rod end (3) was replaced, check toe and
then also steering angle with turning radius gauge (1).
If steering angle is not correct, check if right and left tie rods are
equal in length “A”.
Steering angle
Inside : 35° ± 3°
Outside : 32° ± 3°
Side Slip(Reference)
For inspecting front wheel side slip with side slip tester:
If side slip exceeds limit, toe or front wheel alignment may out not
be correct.
Side slip limit
: Less than 3 mm/m (Less than 0.118 in/3 ft) NOTE:
To prevent possible incorrect reading of camber or
caster, vehicle front end must be moved up and down a
few times before inspection.
NOTE:
If tie rod lengths were changed to adjust steering angle,
reinspect toe-in.

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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” position and negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM)
NOTE:
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
replacement part of lesser quality or substitute design. Torque values must be used as specified dur-
ing reassembly to assure proper retention of these parts.
