INSTALLATION

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.

Note the following, and install in the reverse order of removal.

• To install dash seal (1) to the vehicle, insert dash seal into the

steering gear assembly and press in the protrusions (A) by hand.

CAUTION:

Never allow dash seal lip to run off the engine room side or

passenger room side.

• Follow the instructions below to install intermediate shaft to steer-

ing gear assembly.

- Insert intermediate shaft into steering gear assembly. Align groove

of the steering gear assembly with the bolt hole of the intermediate

shaft.

CAUTION:

The guide protrusion is not required to be reinstalled.

- Check for galling while hand-tightening the mounting bolt of intermediate shaft (steering gear assembly

side). After checking that the bolt is inserted in the groove of steering gear assembly, tighten the bolt to the

specified torque.

• For intermediate shaft mounting bolt direction, refer to 

ST-14, "Exploded View"

. (Do not insert it from the

other side.)

CAUTION:

Never reuse intermediate shaft mounting bolt.

• When connecting intermediate shaft upper side (1) and column

shaft, make sure the bolt is securely seated in groove (A) of col-

umn shaft (A) before final tightening.

• After installing steering column assembly, perform self-diagnosis

with CONSULT to ensure correct operation. Refer to 

STC-9,

"CONSULT Function"

.

• Perform inspection after installation. Refer to 

ST-15, "Inspection"

.

INFOID:0000000012200346

INSPECTION AFTER REMOVAL

• Check each part of intermediate shaft for damage or other malfunctions. Replace if there are any abnormal

conditions.

INSPECTION AFTER INSTALLATION

• Check each part of intermediate shaft for damage or other malfunctions. Replace if there are any abnormal

conditions.

• Rotate steering wheel to check for decentered condition, binding, noise, or excessive steering effort.

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

turning angle. Refer to 

ST-8, "Inspection"

, 

ST-5, "Inspection"

.

• Adjust neutral position of steering angle sensor. Refer to

STEERING GEAR AND LINKAGE

5. Remove steering outer socket from steering knuckle so as not to

damage ball joint boot using suitable ball joint remover (com-

mercial service tool).

CAUTION:

Temporarily tighten the nut to prevent damage to threads

and to prevent the ball joint remover from sudden drop

turning.

6. Remove front suspension member. Refer to 

FSU-17, "Removal

and Installation"

.

7. Remove steering gear assembly.

INSTALLATION

Note the following, and install in the reverse order of removal.

CAUTION:

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

ing gear assembly. Always fix the steering wheel using string to avoid turning.

• Perform final tightening of nuts and bolts on each part under unladen conditions with tires on level ground

when removing steering gear assembly. Check wheel alignment. Refer to 

FSU-7, "Inspection"

.

• Rotate steering wheel to check for decentered condition, binding, noise or excessive steering effort.

• Never reuse steering outer socket mounting nut and steering gear assembly mounting nut.

• Perform inspection after installation. Refer to 

ST-19, "Inspection"

.

Disassembly and Assembly

INFOID:0000000012200349

DISASSEMBLY

1. Loosen outer socket lock nut, and remove outer socket.

CAUTION:

When loosening lock nut, be sure to fix outer socket with a wrench or an equivalent.

2. Remove boot clamps, and then remove boot from inner socket.

CAUTION:

Never damage inner socket part and gear housing part of steering gear assembly when removing

boot. steering gear assembly must be replaced if steering gear assembly are damaged because it

may cause foreign material interfusion.

3. Remove dust cover.
4. Perform inspection after disassembly. Refer to 

ST-19, "Inspection"

.

ASSEMBLY

1. Apply recommended grease to the entire inner perimeter (A) of

the dust cover lip and contact surface (B) of the gear housing

)].

CAUTION:

• Never reuse boot clamp (large diameter).

• Install boot clamp (large diameter) (1) securely to boot

groove, and crimp it so as to have clearance (B) of 3 mm

(0.12 in) or less as shown.

4. Install boot clamp (small diameter) to boot.

CAUTION:

Never reuse boot clamp (small diameter).

5. Adjust inner socket to standard length (L), and then tighten lock

nut (1) to the specified torque. Check length again after tighten-

ing lock nut.

CAUTION:

• When tightening the lock nut (1), be sure to fix outer

socket (2) with a wrench or an equivalent to prevent the

ball joint from getting contact with the knuckle. 

• Adjust toe-in after this procedure. The length achieved

after toe-in adjustment is not necessary the above value.
