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.).

3A-2 FRONT END ALIGNMENT
CAMBER
Camber is the tilting of the front wheels from the vertical, as viewed from the front of the vehicle. When the wheels
tilt outward at the top, the camber is positive. When the wheels tilt inward at the top, the camber is negative. The
amount of tilt is measured in degrees.
PRELIMINARY CHECKS PRIOR TO ADJUSTING FRONT 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. ªLeadº 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 manual 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 en-
sure 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 ball joints. Check tie rod ends; if excessive looseness is noted, it must be corrected before ad-
justing.
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 control 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 ve-
hicle, 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 right and left tie rods by the
same amount to align toe-in to specification.
In this adjustment, right and left tie rods should become equal in
length.
After adjustment, tighten lock nuts to specified torque.
Tightening Torque
(a): 65 N
.m (6.5 kg-m, 47.0 lb-ft)
CAMBER AND CASTER ADJUSTMENT
Should camber or caster be found out of specifications upon in-
spection, locate its cause first. If it is in damaged, loose, bent,
dented or worn suspension parts, they should be replaced. If it is
in body, repair it so as to attain specifications.
To prevent possible incorrect reading of camber or caster, vehicle
front end must be moved up and down a few times before inspec-
tion.

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.
