FRONT SUSPENSION - General Information

GENERAL INFORMATION

33200010181

The front suspension is of a multi-link construction
with two lower arms which create the ideal virtual
kingpin axis for the suspension system. In addition,

by mounting the upper arm in a higher position
than the tyres, excellent steering stability and ride
comfort are obtained.

FRONT SUSPENSION - On-vehicle Service

ON-VEHICLE SERVICE

33100090175

WHEEL ALIGNMENT CHECK AND
ADJUSTMENT
Measure the wheel alignment with the vehicle parked on a
level surface.
The front suspension, steering system, and wheels should
be serviced to normal condition prior to measurement of wheel
alignment.
TOE-IN
Standard value:
At the centre of tyre tread 0±3 mm
Toe angle (per wheel) 0_00’±09’

Clip

(1) If the toe-in is not within the standard value, adjust the
toe-in by undoing the clips and turning the left and right
tie rod turnbuckles by the same amount (in opposite
directions).
NOTE
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.
(2) Use a turning radius gauge to check that the steering
angle is at the standard value. (Refer to GROUP 37A
- On-vehicle Service.)
TOE-OUT ANGLE ON TURNS
To check the steering linkage, especially after the vehicle
has been involved in an accident or if an accident is presumed,
it is advisable to check the toe-out angle on turns in addition
to the wheel alignment.
Conduct this test on the left turn as well as on the right turn.
Standard value:
22_ (inner wheel when outer wheel at 20_)

FRONT SUSPENSION - On-vehicle Service

CAMBER, CASTER AND KINGPIN INCLINATION
MB991004

Standard value:
Camber
0_00’ ± 30’ (difference between right and left wheel:
less than 30’)
Caster
4_20’ ± 1_30’ (difference between right and left
wheel: less than 30’)
Kingpin inclination 7_20’ ± 1_30’
NOTE
1. Camber and caster are preset at the factory and cannot
be adjusted.
2. If camber is not within the standard value, check and
replace bent or damaged parts.
3. For vehicles with aluminium type wheels, attach the
camber/caster/kingpin gauge to the drive shaft by using
the special tool. Tighten the special tool to the same
torque 196 - 255 Nm as the drive shaft nut.
Caution
Never subject the wheel bearings to the vehicle load
when the drive shaft nuts are loosened.

BALL JOINT DUST COVER CHECK

33200860021

(1) Check the dust cover for cracks or damage by pushing
it with finger.
(2) If the dust cover is cracked or damaged, replace the
upper arm assembly, compression lower arm assembly,
lateral lower arm assembly or stabilizer link.
NOTE
Cracks or damage of the dust cover may cause damage
of the ball joint.

UPPER ARM BALL JOINT ROTATION STARTING
TORQUE CHECK
(1) After shaking the ball joint stud several times, install the
nut to the stud and use the special tool to measure the
rotation starting torque of the ball joint.
Standard value: 0.3 - 1.5 Nm
(2) When the measured value exceeds the standard value,
replace the upper arm assembly.
(3) When the measured value is lower than the standard
value, check that the ball joint turns smoothly without
excessive play. If so, it is possible to use that ball joint.
