REAR AXLE – Drive Shaft27-37
REMOVAL SERVICE POINTS
ADRIVE SHAFT NUT REMOVAL
Caution
Do not apply the vehicle weight to the wheel bearing
with the drive shaft nut loosened.
BDRIVE SHAFT REMOVAL
(1) Using the special tool, drive the drive shaft out of the
hub.
(2) Apply a lever to the protrusion of the drive shaft and
remove the drive shaft from the differential carrier.
Caution
(1) Be sure to remove the drive shaft from the
differential side using a lever. Removing it from
the BJ side could damage the parts.
(2) Do not apply the vehicle weight to the wheel
bearing with the drive shaft removed. If it is
unavoidable to apply the weight for reasons of
moving the vehicle, use the special tool to
temporarily secure it in position.
(3) To prevent entry of foreign matter into the
differential carrier, use the special tool as a cover.

INSTALLATION SERVICE POINTS
ADRIVE SHAFT INSTALLATION
Caution
Use care not to allow the drive shaft splines to damage
the oil seal of the differential carrier.
BDRIVE SHAFT NUT INSTALLATION
(1) Install the washer on the drive shaft in the direction shown
on the left.
(2) Using the special tool, tighten the drive shaft nut to the
specified torque.
Caution
Before torquing the drive shaft nut to specification,
do not apply vehicle weight to the wheel bearing.
(3) If, at this time, the split pin holes are not aligned, tighten
the nut further (within 255 Nm {26.0 kgf
m}), insert the
split pin in the first matching holes, and bend it securely.

REAR SUSPENSION – On-vehicle Service34-3
ON-VEHICLE SERVICE
1. REAR WHEEL ALIGNMENT CHECK AND
ADJUSTMENT
(1) The rear suspension and wheels should be serviced to
the normal condition prior to measurement of wheel
alignment.
(2) Measure the wheel alignment with the vehicle parked
on level ground.
1-1 CAMBER
Standard value: –1
00’ ± 30’
(The difference between the left and right wheels
should be 30’ or less.)
NOTE
For vehicles equipped with aluminium wheels, measure the
camber using a compensator. If no compensator is available,
measure the camber after tightening the special tool
(MB991004) to the specified torque 196 – 255 Nm {20.0
– 26.0 kgf
m}.
Caution
Never subject the wheel bearings to the full vehicle load
when the flange nuts/drive shaft nuts are loosened.
If outside the standard value, adjust by the following
procedure.
(1) Adjust by turning the camber adjusting bolt (mounting
bolt for the lower arm and rear crossmember).
Left wheel: clockwise + camber
Right wheel: clockwise – camber
The scale has gradations of approximately 14’.
(2) After adjusting the camber, be sure to adjust the toe-in.
1-2 TOE-IN
Standard value:
At the centre of tyre tread 3 ± 2 mm
If outside the standard value, adjust by the following
procedure.
(1) Be sure to adjust the camber before adjusting the toe-in.
(2) Adjust by turning the toe adjusting bolt (inner mounting
bolt toe control arm).
LH: Turning clockwise → toe-in direction
RH: Turning clockwise → toe-out direction
The scale has gradations of approximately 3.3 mm (single
side toe angle equivalent to 19’).
2. 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
appropriate suspension arm assembly or stabilizer link.
NOTE
Cracks or damage of the dust cover may cause damage
of the ball joint.

2. INSPECTION PROCEDURE FOR DIAGNOSTIC TROUBLE CODES
Code Nos.11, 12, 13 and 14: Wheel speed sensor
(open circuit or short circuit)Probable cause
Code Nos.21, 22, 23 and 24: Wheel speed sensor
Code Nos 11, 12, 13 and 14 are output if the ABS-ECU detects an open circuit or
short-circuit in the (+) wire or (–) wire in any one of the four wheel speed sensors.
Malfunction of wheel speed sensor

Malfunction of wiring harness or connector

Malfunction of ABS-ECU
Code Nos.21, 22, 23 and 24 are output in the following cases.

When there is no input from any one of the four wheel speed sensors when travelling
at 8 km/h or more, even though open circuit can not be verified.

When a chipped or blocked-up ABS rotor is detected and if the anti-lock system
operates continuously because a malfunctioning sensor or a warped ABS rotor
is causing sensor output to drop.
Malfunction of wheel speed sensor

Malfunction of wiring harness or connector

Too much gap between the sensor and the rotor

of the four wheel speed sensors while driving (except for an open circuit or short
circuit).

ABS – Troubleshooting35B-14
INSPECTION PROCEDURE 4
When the ignition key is turned to “START”, the ABS
warning lamp does not illuminate.
Probable cause
The ABS-ECU is powered through IG2 which is turned off when the ignition key
is in START position. The ABS warning lamp is powered through IG1 which is not
turned off even when the ignition key is in START position. So the cause must be
a defective circuit on valve relay side.
Malfunction of wiring harness or connector

Malfunction of valve relay

bination meter and valve relay, and
repair if necessary.

INSPECTION PROCEDURE 5
Brake operation is abnormal
Probable cause
The varies depending on the driving conditions and the road surface conditions, so
problem diagnosis is difficult. However, if a normal diagnosis code is displayed, carry
out the following inspection.
Improper installation of wheel speed sensor

Incorrect sensor harness contact

Foreign material adhering to wheel speed sensor
