• After tightening nut (A) of the steering column assembly, press in

slide plate (outer and inner) (1) to tighten nut (B).

CAUTION:

The slide plate must be securely pressed in before tightening

the nut of slide plate (outer and inner).

• For intermediate shaft bolt direction, refer to 

ST-38, "Exploded

View"

.

CAUTION:

• Do not insert intermediate shaft bolt from the other side.

• Do not reuse intermediate bolt.

• Measure steering column assembly rotating torque using a preload

gauge (A) [SST: ST3127S000 (J-25765-A)]. Replace steering col-

umn assembly if the rotating torque is outside the standard.

• Measure the length “L” shown in the figure, if vehicle has been

involved in a minor collision. Replace steering column assembly

(with motor, reduction gear, sensor) if “L” is outside the standard.

INSPECTION AFTER INSTALLATION

• Check each part of steering column assembly for damage or other malfunctions. Replace if there are any

abnormal conditions.

• Check the steering wheel play, neutral position steering wheel, steering wheel turning force, and front wheel

turning angle.

- Steering wheel play: Refer to 

ST-33, "Inspection"

.

- Neutral position steering wheel, steering wheel turning force, and front wheel turning angle: Refer to 

ST-16,

"Inspection"

.

• Check tilt mechanism operating range “T” shown in the figure.

• Adjust neutral position of steering angle sensor. Refer to 

BRC-70,

REMOVAL

CAUTION:

Spiral cable may be cut if steering wheel turns while separating steering column assembly and steer-

ing gear assembly. Be sure to secure steering wheel using string to avoid turning.
1. Set vehicle to the straight-ahead position.
2. Place the tilt to the lowest level.

CAUTION:

Securely lock the tilt lever.

3. Remove instrument lower panel LH. Refer to 

IP-17, "Removal and Installation"

.

4. Remove intermediate shaft bolt (steering gear side), and separate intermediate shaft from steering gear

assembly.

CAUTION:

• Place a matching mark on both intermediate shaft and steering gear assembly before removing

intermediate shaft.

• When removing intermediate shaft, do not insert a tool, such as a screwdriver, into the yoke

groove to pull out the intermediate shaft. In case of the violation of the above, replace intermedi-

ate shaft with a new one.

5. Remove intermediate shaft bolt (steering column side), and remove intermediate shaft from steering col-

umn assembly.

CAUTION:

• Place a matching mark on both intermediate shaft and steering column assembly before remov-

ing intermediate shaft.
