REAR AXLE – LSD Case Assembly <Vehicles without AYC>27-48
BSCREW TIGHTENING
(1) Align the alignment mark on differential case A with that
on differential case B.
(2) Tighten the screws connecting differential case A and
B a uniform amount little by little in the diagonal order.
NOTE
If tightening the screws does not bring the two cases
properly together, spring plates are not probably
assembled properly. Reassemble from the start.
CLSD DIFFERENTIAL TORQUE CHECK
(1) Using the special tool, check for differential torque.
Standard value:
When new clutch plate is
installed Nm {kgf
m}When existing clutch plate is
reused Nm {kgf
m}
5 – 19 {0.5 – 1.9}2 – 19 {0.2 – 1.9}
NOTE
Before measuring the differential torque, first turn the
gears so they snug each other, then take measurements
during rotation.
(2) If the measurement falls outside the specified range,
disassemble the differential case assembly and repair
or replace defective parts.
INSPECTION
1. DIFFERENTIAL CASE INTERNAL PARTS
CONTACT/SLIDING SURFACE CHECK
(1) Clean the disassembled parts with cleaning oil and dry
them with compressed air.
(2) Check each plate, disc, and pressure ring for the following:
A. Friction and sliding surfaces of friction discs, friction
plates, and spring plates.
Replace a defective part with heat discoloration and
excessive wear with a new one, as it degrades locking
performance.
NOTE
If the inner periphery of the friction face shows traces
of harsh contact, it is because of the spring tension
of each plate, disc and other part. Do not confuse
this with abnormal wear.
B. Inner periphery and outer periphery protrusions of
friction discs, friction plates, and spring plates.
Replace a cracked or damaged part with a new one.
C. Friction and sliding surfaces between pressure rings
and friction discs.

and grease from flowing out, ensure that protrusion
A of the ball joint stud from knuckle measures 4 mm
or less during installation of the lower arm assembly.
(2) Should the knuckle be pushed in excessively and grease
flow out from the dust cover, replace the dust cover with
a new one.
(3) Check that there is no clearance between the knuckle
and dust cover.

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.
