SERVICE ADJUSTMENT PROCEDURES
REAR WHEEL ALIGNMENT INSPECTIONN17FAAC
The rear suspension assembly must be free of worn, loosen or
damaged parts prior to measurement of rear wheel alignment.
Standard value:
Toe-in (Left-right difference)
Of3 mm (Of.118 in.)
Camber-45’ + 30’
NOTEThe rear wheel alignment is set at the factory and cannot be
adjusted.If toe-in or camber is not within the standard value, replace
bent or damaged parts.
WHEEL BEARING END PLAY ADJUSTMENT,7FBA0
1.Inspect the play of the bearings while the vehicle is jacked
up and resting on floor jack.
2.Remove the hub cap and then release the parking brake.
3. 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 isend play.
Limit: 0.01 mm
(.004 in.) or less
NOTE12AO531If 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.

(1) Supporting the rear suspension assembly with a trans-
mission jack, move it toward the rear (in the direction of
wtthe fuel tank).
c1(2) Gradually lower the transmission jack, avoiding contact
with the stabilizer bar and the propeller shaft.
Caution
1. Ensure that the propeller shaft does not bend
greatly.
2.Ensure that the liibro joint does not receive any
shock.
NOTEThe lowering of the rear suspension assembly from the
transmission jack requires three individuals due to the
amount of weight being handled (one on the differen-
tial, and one on either side of the lower arm).
(3) In order to protect the rear suspension assembly dust
shield, support the lower arm ball joint with a wooden
block.

l Check the ball joint dust cover for cracks.
l Check all bolts for condition and straightness.
CHECKING OF BALL JOINT FOR STARTING TORQUE
(1) If a crack is noted in the dust cover, replace it, adding
grease.(2) Deflect side to side the ball joint stud several times.
(3) Mount two nuts on the ball joint, and then measure the ball
joint starting torque.
“,Standard value: 2-9 Nm (17-78
in.lbs.)(4) If the starting torque exceeds the upper limit of standard
value, replace the upper and lower arm assembly.
(5) Even if the starting torque is below the lower limit of the
standard value, the ball joint may be reused unless it has
drag and excessive play.
