SERVICE ADJUSTMENT PROCEDURES
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.

1. REMOVAL OF BRAKE HOSE AND TUBE BRACKET
Do not pry the brake hose and tube clamp away when
removing it.
i. REMOVAL OF STRUT LOWER MOUNTING BOLTS
After the union between the strut and the knucke has
been removed, jack up the lower arm, attaching the brake hose, tube and drive shaft to the knuckle with wire so that
they will not be pulled on.

INSPECTIONMasLcAB
l Check for oil leaks from the strut assembly.
lCheck the strut assembly shock absorber for damage or
deformation.

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.

2. REMOVAL OF SELF-LOCKING NUT (1) Holding the spring upper seat with the special tool,loosen the self-locking nut.
Caution
The self-locking nut should be loosened only, not
removed.
(2) Using the special tools, compress the coil spring, and
then remove the self-locking nut.
NOTE
Install the special tools evenly, and so that the
maximum length will be attained within the installation
range.
9. REMOVAL OF STRUT ASSEMBLY
If it is to be discarded, place it horizontally with the piston
rod sticking out and drill a hole approximately 3 mm
(.12 in.)
in diameter in the position shown in the figure to release
the gas.
Caution
The gas is non-toxic but wear protective glasses
because there is danger that dust from the drill, etc.
may fly out along with the gas.
INSPECTIONM33LGAE
l Check the strut insulator bearing for wear or rust.
l Check the rubber parts for damage or deterioration.
l Check the spring for deformation, deterioration or dam-
age.
l Check the shock absorber for deformation.

4. INSTALLATION OF SPRING UPPER SEAT ASSEMBLY
(1) Assemble the sprivg upper seat to the piston rod,
fitting the notch in the rod to the shaped hole in spring
seat.
(2) Line up the holes in the strut assembly spring lower seat with the hole in the spring upper seat.
NOTE
The job is easily accomplished with a pipe [alO
mm x
300 mm
(0.4 in. x 11.8 in.)].
I2. INSTALLATON OF SELF-LOCKING NUT
(1) With the coil spring held compressed by the special
tools (MB991237
and
MB991238), temporarily tighten
the self-locking nut.
(2) Correctly align both ends of the coil spring with the
grooves in the spring seat, and then loosen the special
tools (MB991237
and
MB991238).
(3) Using the special tool, tighten the strut insulator at the
specified torque.
