FRONT WHEEL ALIGNMENTM33FBAQ
NOTE
The front suspension assembly must be free of worn, loose or
damaged parts prior to measurement of front wheel align- ments. Measure wheel alignment by using the tool.
CAMBER AND CASTER
Standard value:

Camber22’ f 30’ 31’& 30
Caster2”f301”56’rtr30
Camber and caster are pre-set at the factory and cannot be
adjusted.
NOTE
If camber and caster are not within specifications, replace bent
or damaged parts.
TOE-IN
Standard value: Ok3 mm (Of .12 in.)
1. Adjust the toe-in by undoing the clips and turning the left and right tie rod turnbuckles
by the same amount (in
opposite directions).
2. The toe will move out as the left turnbuckle
is turned
toward the front of the vehicle and the right turnbuckle is
turned toward the rear of the vehicle.
3.For each half turn of the left and right tie rods, the toe-in will
be adjusted by 6 mm
(24 in.).
4.After making the adjustments, use a turning radius gauge to confirm that the steering wheel turning angle is within the
standard value range. (Refer to GROUP
37A-Service
Adjustment Procedures.)
WHEEL BEARING ADJUSTMENTM?SCAA
Bearing preload is pre-set to the specified value by design and
therefore can not be adjusted.

4. INSTALLATION OF STRUT ASSEMBLY
Install the strut assembly so that the strut insulator faces
in the direction indicated in the illustration.
NOTE
Be sure to confirm that the direction is correct, because
there will be a deviation of the wheel alignment if it is not.

HUB END PLAY INSPECTION
1. Jack up the vehicle and remove the front wheels.
2.Remove the disc brake caliper and suspend it with a wire.
Refer to GROUP 26 FRONT AXLE-Service Adjustment
Procedures.
3.Attach a dial indicator as shown in the illustration, and then measure the axial play while moving the hub back and
forth.
Limit: 0.2 mm t.008
in.) or less
NOTE
Secure the brake disc and hub by the wheel nut so that the
brake disc won’t come of the hub.
4.If axial play exceeds the limit, disassemble and check parts.

(3) Connect the air tube at the shut-off valve side of the
special tool (air-pressure gauge) to the air tube side, and
the other one to the strut assembly.
The installation at the strut side is done by using the special tool (adaptor set).
Caution
To prevent the entry of moisture during the strut
assembly air leak check, utilize air from the dryer.
(4) Remove the compressor connector, then operate it by connecting it directly to the battery.
NOTE
Refer to P.33B-126 for compressor connector array.
(5) Insert
the strut assembly into a water tank and check for air
leakage at a pressure of about 500
kPa (71 psi). Caiition
1. Don’t mistake the rise of bubbles attached to the outside of the strut for air leakage.
2.Dry the strut with an air blower after the check has
been completed.
(6) When air leakage is found, check the strut assembly and replace it as necessary.
CHECKING THE ACTUATOR For detailed information concerning the checking of the
actuator, refer to the troubleshooting guide and to the service
adjustment procedures section.
SERVICE POINTS OF INSTALLATION

13. INSTALLATION OF STRUT ASSEMBLY Install the strut assembly so that the strut insulator is in
the direction shown in the figure.
NOTE
Be sure to check to be sure that the installation direction is
correct, because if it is not the wheel alignment will be
incorrect.
2. INSTALLATION OF AIR TUBE
(1) After coating the O-ring with rubber grease, install the
O-
ring, bush and flare nut to the strut assembly.
Caution 1. The O-ring may be damaged if it is installed at the
air tube side when the connection is made.
2. The bush must be installed so that the projection part is facing in the direction indicated in the
illustration.

SERVICE ADJUSTMENT PROCEDUEZ$
REAR WHEEL ALIGNMENT INSPECTION
The rear suspension assembly must be free of worn, loosen or
damaged parts prior to measurement of rear wheel alignment.
Standard value: Toe-in (Left-right difference)
0+3 mm (Ok.118
in.)
Camber-45’ f 30’
NOTE
The rear wheel alignment is set at the factory and cannot be
adjusted. If toe-in or camber is not within the standard value, replace
bent or damaged parts.

SERVICE ADJUSTMENT. PROCEDURES
REAR WHEEL ALIGNMENT INSPECTION mm
The rear suspension assembly must be free of worn, loosen or
damaged parts prior to measurement of wheel alignment.
TOE-IN
(1) Measure the toe-in with a toe-in gauge.
Standard value:
3+3 mm (.12+.12 in.)
(2) If the toe-in is not within the standard value, adjust it by moving the mounting bolts located on the crossmember
side of the trailing arm.
NOTE
Make the adjustment by moving the left and the right bolts
equally.
Movement of one division on the scale will cause toe-in
variation of about 2 mm
(.08 in.).
CAMBER
(1) Measure the camber with a camber/caster/kingpin gauge.
Standard value:
-1”OO’f30’
(2) If the camber is not within the standard value, adjust it bymoving the mounting bolt located on the crossmember
side of the upper arm.
NOTE
Movement of one division on the scale will cause camber
variation of about 15’.
Caution
1. As toe-in will vary 0.9 mm LO35 in.) for every
camber scale adjustment, adjust the toe after
adjusting camber.
2. The difference between the left and the right camber shall be less than 15’.
