out of service.
2) Warm up engine to normal operating tem-
perature.
3) Connect CO tester to mufler tail pipe.
4) With the engine warmed up, keep the engine
speed at 1,500 to 2,000 r/min. (t-pm). If the
CO concentration is 0.4% or less in this state,
the catalytic converter is in good condition.
If it exceeds the specification, refer to DIA-
GNOSIS (p. 5-15).

Parking Brake Cable
Inspect brake cable for damage and smooth
movement. Replace cable if it is in deteriorat-
ed condition.
36. TIRE INSPECTION AND ROTATION
1) Check tires for uneven or excessive wear, or
damage. If defective, replace.
2) Check inflating pressure of each tire and
adjust pressure to specification as necessary.
NOTE:
l Tire inflation pressure should be checked
when tires are cool.
l Specified tire inflation pressure should be
found on tire placard or in owners’ manual
which came with the car.
3) Rotate tires.
For the details of above steps 1) to 3), refer
to MAINTENANCE SERVICE (p. 18-19 and
18-20) of SECTION 18.
37. WHEEL DISCS AND FREE WHEELING
HUBS (if equipped) INSPECTION
Wheel Discs
Inspect each wheel disc for dents, distortion and
cracks. A disc in badly damaged condition must
be replaced.
Free Wheeling Hub
This is applicable to the car equipped with
free wheeling hubs.
Check free wheeling hub for proper operation
by moving free wheeling hub knob to LOCK
and FREE positions. (The same check on both
right and left wheels)
For checking procedure, refer to MAINTE-
NANCE SERVICE (p. 17-29) of SECTION 17.
38. STEERING KNUCKLE OIL SEAL
REPLACEMENT
For replacement procedure, refer to MAIN-
TENANCE SERVICE (p. 17-23) of SECTION
17.
39. WHEEL BEARING INSPECTION
[Inspection of wheel bearing]
1) Check front wheel bearing for wear, damage,
abnormal noise or rattles. For the details,
refer to MAINTENANCE (p. 17-20 and
17-21) of SECTION 17.
2) Check rear wheel bearing for wear, damage
abnormal noise or rattles. For the details,
refer to MAINTENANCE SERVICE (p. 17-24)
of SECTION 17.
[Inspection of front wheel bearing grease]
1) Remove wheel hub and spindle referring to
FRONT WHEEL HUB REMOVAL of SEC-
TION 17.
2) Check grease around front wheel bearing
rollars and between front axle shaft surface
and wheel spindle bush for deterioration and
capacity.
If grease is deteriorated, remove grease tho-
roughly and apply enough amount of new
SUZUKI SUPER GREASE A or wheel bearing
grease. If grease is found insufficient, add some
more.

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

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
