43. LEAF SPRING lNSPECTlON
Check leaf spring for wear, crack and damage.
(Where each end of the shorter leaf contacts.)
If excessive wear of cracking is noted, replace
the spring with a new one.
44. BOLTS AND NUTS TIGHTENING
Check suspension bolts and nuts for tightness
and retighten them as necessary.
Repair or replace defective parts, if any.
NOTE:
For the details of check points, refer to the
table of MAINTENANCE SERVICE (p. 17-24)
of SECTION 17.
45. STEERING SYSTEM INSPECTION
1) Check steering wheel for play and rattle,
holding car in straight forward condition on
the ground.
Steering wheel play10 - 30 mm
(0.4 - 1.2 in.)
3) Check bolts and nuts for tightness and retigh-
ten them as necessary. Repair or replace
defective parts, if any.
Refer to MAINTENANCE SERVICE on p.
18-18 for particular check points.
4) Inspect steering gear box for evidence of oil
leakage. If leakage is found, check oil level
in gear box.
NOTE:
For the details of the above steps 1) to 41, refer
to MAINTENANCE SERVICE (p. 18-18) of
SECTION 18.
.5) Check boots of tie rod ends for damage. If
damage is found, replace it with a new one.
6) Check wheel alignment.

FINAL INSPECTION
Carry out road test in safe place.
WARNING:
When carrying out the following road
tests, select a safe place where no man or
no running car is seen so as to prevent any
accident.
1) Engine start
Check engine start for readiness.
2) Clutch
Check the following:
l that clutch is completely released when
depressing clutch pedal,
l that no slipping clutch occurs when releas-
ing pedal and accelerating,
l and that clutch itself is free from any
abnormal condition.
3) Gearshift Lever (Transmission and Transfer)
Check gearshift lever for smooth shifting
to all positions and for good performance of
transmission and transfer in any position.
4) Brake
[Foot brake]
Check the following when depressing brake
pedal while driving;
l that brake works properly,
l that it is free from noise,
l and that braking force applies equally on
all wheels.
[Parking brake]
Check to ensure that parking brake is fully
effective when the car is stopped on the slop
and brake lever is pulled all the way.
5) Steering
Check to ensure that steering wheel is free
from instability, or abnormally heavy feeling
while driving.
