INSPECTION
1. INSPECT SPEEDOMETER ON-VEHICLE
Using a speedometer tester, inspect the speedometer for allow-
able indication error and check the operation of the odometer.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.
If error is excessive, replace the speedometer.

2. INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from battery to terminal 1
and negative (-) lead to terminal 2.
(b) Connect the positive (+) lead from tester to terminal 3 and
negative (-) lead to terminal 2.
(c) Rotate shaft.
(d) Check that there is voltage change from approx. 0 V to 11
V or more between terminals 2 and 3.
HINT:
The voltage change should be 4 times for every revolution of
the speed sensor shaft.
If operation is not as specified, replace the sensor.
3. INSPECT TACHOMETER ON-VEHICLE
(a) Connect a tune-up test tachometer, and start the engine.
NOTICE:
Reversing the connection of the tachometer will damage
the transistors and diodes inside.
(b) Compare the tester and tachometer indications.
If error is excessive, replace the tachometer.

(b) Check the tire runout.
Tire runout: 1.4 mm (0.055 in.) or less
2. INSPECT WHEEL BALANCE
(a) Check and adjust the Off-the-car balance.
(b) If necessary, check and adjust the On-the-car balance.
Imbalance after adjustment: 5.0 g (0.011 lb) or less
3. CHECK WHEEL BEARING LOOSENESS
(a) Check the axle bearing backlash.
Maximum: 0.05 mm (0.0020 in.)
(b) Check the axle hub deviation.
Maximum: 0.05 mm (0.0020 in.)
4. CHECK FRONT SUSPENSION FOR LOOSENESS
5. CHECK STEERING LINKAGE FOR LOOSENESS
6. CHECK BALL JOINT FOR LOOSENESS
7. CHECK SHOCK ABSORBER WORKS PROPERLY

Check for oil leak.
