InspectionINFOID:0000000006225584
NEUTRAL POSITION STEERING WHEEL
1. Check that steering gear assembly, steering column assembly and steering wheel are installed in the cor-
rect position.
2. Perform neutral position inspection after wheel alignment. Refer to FSU-7, "
Inspection".
3. Set vehicle to the straight-ahead position and c onfirm steering wheel is in the neutral position.
4. Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if steering wheel is not in the neutral position.
STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Tires need to be inflated the specified pressure. Refer to WT-69, "
Tire Air Pressure".
3. Start the engine.
4. Bring power steering fluid up to adequate operating temperature.
5. Check steering wheel turning force when steering wheel has been turned 540 ° from neutral position.
NOTE:
Multiply the distance (L) from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
6. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to ST-52, "
Inspection".
RACK SLIDING FORCE
1. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to ST-41, "Exploded
View".
2. Start and run engine at idle to make sure steer ing fluid has reached normal operating temperature.
3. While pulling outer socket slowly in ±11.5 mm ( ±0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
4. If rack sliding force is not within specification, overhaul steering gear assembly.
FRONT WHEEL TURNING ANGLE
1. Check front wheel turning angle after toe-in inspection. Refer to FSU-7, "Inspection".
Fluid temperature : 50 – 80
°C (122 – 176 °F)

INSPECTION
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle
so that the A/T fluid temperature is 50 to 80°C (122 to
176 °F). Inspect the amount of AT F. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Start the engine, apply foot brake, and place selector lever in “D” position.
5. Gradually press down the accelerator pedal while holding down the foot brake.
6. Quickly read off the stall speed, and quickly release the accelerator pedal. CAUTION:
Never hold down the accelerator pedal for more than 5 seconds during this test.
7. Shift the selector lever to “N” position.
8. Cool down the ATF. CAUTION:
Run the engine at idle for at least 1 minute.
9. Repeat steps 5 through 8 with selector lever in “R” position.
