CAMBERStandard value: 0” + 30
To adjust camber, turn the lower arm mounting bolt
(cross-
member side).
NOTE(1) Make the adjustment with the assist link mounting bolt
(crossmember side) loosened.
(2) The difference between the right and left wheels should be30’ or less.
(3) Left wheel: Clockwise
(0 camber)
Right wheel: Clockwise
(0 camber)
One graduation changes camber by about 15’.
TOE-INStandard value: 0.5
-+ 2.5 mm (.Ol + .09 in.)
To adjust toe, turn the assist link mounting bolts (on crossmem-ber side) on both sides
t,he same amount.
NOTE
(1) The difference between right and left wheels should be 3mm (.I2 in.) or less.
(2) Left wheel: Clockwise (toe-in)
Right wheel: Clockwise (toe-out)
One graduation changes toe by about 4.8 mm
(.19 in.)
.
Caution1. Adjust the eccentric bolt within 90” from the central
position.
2.Adjust camber and toe, in that order, and, if camber isadjusted, be sure to adjust toe also.

WHEEL BEARING END PLAY INSPECTIONM34FBAG
1.Inspect the play of the bearings while the vehicle is jackedup and resting on floor jack.
2. Remove the hub cap and then release the parking brake.
s&i3. Remove the caliper assembly and the brake disc.
4. Check the bearing’s end play.
Place a dial gauge against the hub surface; then move the
hub in the axial direction and check whether or not there is
end play.Limit: 0.05 mm
(.002 in.) or less
NOTEIf the limit value is exceeded, the lock nut should be
tightened to the specified torque and check the end play
again.5. Replace the rear hub bearing unit if an adjustment cannot
be made to within the limit.
REAR HUB ROTARY-SLIDING RESISTANCE (TOR-
QUE) INSPECTION
M34FCAC
1.Inspect the play of the bearings while the vehicle is jackedup and resting on floor jack.
2. Release the parking brake.
3. Remove the caliper assembly and the brake disc.
..J
4.After turning the hub a few times to seat the bearing, attach
a spring balance to the hub bolt, and, pulling at a 90” anglefrom the hub bolt, measure to determine whether or not
the rotary-sliding resistance of the rear hub (the
rotary-sliding torque of the rear hub) is the standard value.
Limit:
Rear hub rotary-sliding resistance
31 N (7 Ibs.) or lessRear hub rotary-sliding torque
1.8 Nm (1.30 ftlbs.) or less
NOTEIf the limit value is exceeded, the lock nut should be
tightened to the specified torque and check the end play
again.5. Replace the rear hub unit bearing if an adjustment cannot
be made to within the limit.

1.REMOVAL OF REAR SPEED SENSOR ABS>Caution
Be careful when handling the pole piece at the tip of the
speed sensor and the toothed edge of the rotor so as
not to damage them by striking against other parts.
2. REMOVAL OF CALIPER ASSEMBLY
Remove the caliper assembly and suspend it with a piece of
wire.
8. REMOVAL OF REAR ROTOR ABS>Caution
Care must be taken not to scratch or scar the rotor’s
toothed surface, and not to drop it.
If the rotor’s toothed surface is chipped or the rotor is
deformed, it might not be able to accurately sense the
wheel rotation speed and the system as a result might
not perform normally.
