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
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
.
• Perform inspection after installation. 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
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
• 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
.
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
.
ASSEMBLY
1. Apply recommended grease to the entire inner perimeter (A) of
the dust cover lip and contact surface (B) of the gear housing
part, and install dust cover to steering gear assembly.
Use Genuine Lithium Soap, Wanlouver No.2 (manufactured
by Kyodo yushi) or equivalent.

CAUTION:
Never reuse boot.
3. Install boot clamp (large diameter) (1) to boot using boot band
crimping tool (A) [SST: KV40107300 (
—
)].
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.

BALL JOINT SWINGING FORCE
• Hook a spring balance at the point shown in the figure and pull the
spring balance. Make sure that the spring balance reads the spec-
ified value when ball stud and inner socket start to move. Replace
outer socket or steering gear assembly (inner socket) if they are
outside the standard.
BALL JOINT AXIAL END PLAY
• Apply an axial load of 490 N (50 kg, 110 lb) to ball stud. Using a
dial gauge, measure amount of stud movement, and then make
sure that the value is within the following specified range. Replace
outer socket (1) steering gear assembly (inner socket) (2) if the
measured value is outside the standard.
INSPECTION AFTER INSTALLATION
• Check if steering wheel turns smoothly when it is turned several times fully to the end of the left and right.
• Check the steering wheel play, neutral position steering wheel, steering wheel turning force, and front wheel
turning angle. Refer to
.
• Adjust neutral position of steering angle sensor. Refer to
.
