Install the lower arm assemblies according to the identification
mark stamped in the illustrated position.
INSPECTION
1. TOE CONTROL ARM BALL JOINT TURNING
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
turning torque of the ball joint.
Standard value: 0.5 – 2.5 Nm {5 – 25 kgf
cm}
(2) When the measured value exceeds the standard value,
replace the toe control 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.

2. TOE CONTROL ARM SLIDE BUSHING OPERATING
TORQUE CHECK
(1) Insert a bolt into the slide bushing of the toe control arm.
Fit a washer onto the bolt from the opposite end and
screw a nut onto it. Turn the inner cylinder (together with
the washer) several turns, then measure the toe control
arm slide bushing operating torque using the special tool.
Standard value: 0.2 – 1.5 Nm {2 – 15 kgf
cm}
(2) If the measurement exceeds the standard value, replace
the toe control arm assembly.
(3) If the measurement falls short of the standard value, check
that the slide bushing turns smoothly without excessive
play. If so, the slide bushing should still be in good condition
for continued use.
3. TOE CONTROL ARM BALL JOINT DUST COVER
CHECK
(1) Check the dust cover for cracks or damage by pushing
it with a finger.
(2) If the dust cover is cracked or damaged, replace the
toe control arm assembly.
NOTE
A cracked or damaged dust cover can lead to a damaged
ball joint.
If the dust cover is damaged during servicing, replace
it with a new one.
TOE CONTROL ARM BALL JOINT DUST
COVER REPLACEMENT
Only when the dust cover is damaged accidentally during
service work, follow these steps to replace it with a new one.
(1) Remove the dust cover.
(2) Pack and apply the specified grease to the inside and
lips of the dust cover.
Molybdenum disulfide-base chassis grease:
SHOWA SHELL SEKIYU SUNLITE MB2, NISSEKI
CLAKNOCK FL, or equivalent
(3) Using the special tool, press the dust cover until it contacts
the snap ring.
(4) Push the dust cover with a finger to ensure that it is
free from cracks or damage.

ASTABILIZER BAR / BUSHING / STABILIZER BAR
BRACKET INSTALLATION
Position the stabilizer bar such that the identification mark
may protrude toward the vehicle center as shown in the figure,
and tighten first the stabilizer bar bracket mounting bolt 1
then the mounting bolt 2.
INSPECTION
1. STABILIZER LINK BALL JOINT TURNING 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
turning torque of the ball joint.
Standard value: 1.7 – 3.1 Nm {17 – 32 kgf
cm}
(2) When the measured value exceeds the standard value,
replace the stabilizer link.
(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.
2. STABILIZER LINK BALL JOINT DUST COVER
CHECK
(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
stabilizer link.
NOTE
Cracks or damage of the dust cover may cause damage
of the ball joint. When it is damaged during service work,
replace the dust cover.

(3) Wrap plastic tape on the stabilizer link threads as shown
in the illustration, and then install the dust cover to the
stabilizer link.
(4) Secure the dust cover with the clip ring.
When installing the clip ring, align the ends at a 90

angle from the axis of the stabilizer link.
(5) Check the dust cover for cracks or damage by pushing
it with finger.

BASIC BRAKE SYSTEM – General / On-vehicle Service35A-2
GENERAL
OUTLINE OF CHANGE

The service procedures for left-hand drive vehicles have been established as described below.

The service procedures for the front and rear disc brakes have been changed since they had been
replaced by a different type.
ON-VEHICLE SERVICE
BRAKE PEDAL CHECK AND ADJUSTMENT

1. Turn up the carpet, etc under the brake pedal.
2. Measure the brake pedal height as illustrated. If the brake
pedal height is not within the standard value, follow the
procedure below.
Standard value: 163.5 –166.5 mm
(1) Disconnect the stop lamp switch connector.
(2) Adjust the brake pedal height by turning the operating
rod with pliers (with the operating rod lock nut
loosened), until the correct brake pedal height is
obtained.
(3) Secure by tightening the lock nut of the operating
rod.
(4) Push the stop lamp switch in the direction of the
pedal stroke until it stops. (The switch will slide if
it is pushed firmly.)
(5) Lift up the pedal until the operating rod is fully
extended, and then slide the stop lamp switch back
to the required position. Adjust the position of the
switch by turning it until the distance shown in the
illustration is correct.
(6) Connect the connector of the stop lamp switch.
(7) Check that the stop lamp is not illuminated with the
brake pedal unpressed.
3. With the engine stopped, depress the brake pedal two
or three times. After eliminating the vacuum in the power
brake booster, press the pedal down by hand, and confirm
that the amount of movement before resistance is met
(the free play) is within the standard value range.
