NEUTRAL POSITION STEERING WHEEL
1. Check that steering gear assembly, steering column assembly and steering wheel are installed in the cor-
rect position.
2. Check wheel alignment within specification. Refer to
3. Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
• 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.
CAUTION:
If the adjustment is performed by using the inner socket, check wheel alignment after the adjust-
ment. Refer to
.
STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Tires need to be inflated normal pressure. Refer to
3. Set the vehicle to READY.
4. Check steering wheel turning force using Tool when steering
wheel has been turned 360
° from the neutral position.
FRONT WHEEL TURNING ANGLE
1. Perform toe-in inspection. Refer to
CAUTION:
Perform front wheel turning angle inspection, after toe-in inspection.
2. Place front wheels on turning radius gauges and rear wheels on
stands, so that vehicle can be level.
3. Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.

• Set the vehicle to READY and fully steer right and left to check
the steering angle (maximum inner wheel steering angle and
maximum outer wheel steering angle).
• Check the following items when turning angle is out of the standard.
- Check rack stroke (L).
- If rack stroke is out of specification, replace steering gear
assembly.
• Steering angles are not adjustable. Check steering gear
assembly, steering column assembly, and front suspension
components for wear or damage if any of the turning angles
are different from the specified value. Replace any of them, if
any non-standard condition exists.
