CAUTION:

Do not allow axial impact to steering column assembly during removal and installation.

Steering column must be kept at maximun tilt up position during removal and installation. Do not
operate tilt mechanism while steering column is out of the vehicle.

Put matching mark on intermediate shaft and steering column assembly before removing interme-
diate shaft.

When steering wheel is turned repeatedly with the vehicle stopped, care must be taken because
motor and EPS control unit may get too hot.

Steering column assembly is heavy. Care must be taken when removing steering column assem-
bly from vehicle.

Do not put steering column assembly near the things that generate excessive magnetic force.

Steering column assembly (with motor, reduction gear, sensor) cannot be disassembled.
REMOVAL
1. Set vehicle to the straight ahead-position.
2. Remove driver air bag module. Refer to SRS-41, "
DRIVER AIR BAG MODULE" .
3. Remove steering wheel. Refer to PS-8, "
Removal and Installation" .
4. Remove steering column cover (upper and lower). Refer to IP-10, "

INSPECTION AFTER REMOVAL

Check each part of steering column assembly, EPS control unit and intermediate shaft for damage and .
replace as necessary.

Measure the length “L” as shown, if vehicle has been involved in
a minor collision. Replace steering column assembly (with
motor, reduction gear, sensor) if outside the standard.

Check tilt mechanism for damage or other malfunctions.
Replace steering column assembly (with motor, reduction gear,
sensor) as necessary.

Measure steering column assembly rotating torque using Tool.
Replace steering column assembly (with motor, reduction gear, sensor) if outside the standard.
INSTALLATION
Installation is in the reverse order of removal.

Installation is in the reverse order of removal. For tightening torque, refer to PS-9, "COMPONENT" .

When tightening bolt (intermediate shaft lower side), tighten it by hand first, and make sure there is no
feeling of sticking or galling before final tightening.
CAUTION:
Insert bolt in the proper direction. (Do not insert it from the other side.)

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.
INSPECTION AFTER INSTALLATION

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

After installing steering column assembly, perform self-diagnosis with CONSULT-II to ensure correct oper-
ation. Refer to STC-13, "
CONSULT-II Function (EPS)" . Steering column

INSPECTION AFTER DISASSEMBLY
Joint Cover
Check joint cover protrusion for damage. Replace if there are.
Rack and Pinion Assembly

Check pinion assembly for damage or wear. Replace as necessary.

Rotate pinion assembly and check for torque variation or rattle. Replace steering gear as necessary.
Gear Housing Assembly
Check gear housing assembly for damage or scratches. Replace steering gear as necessary.
Outer Socket and Inner Socket
1. Check ball joint swinging torque.

Hook a spring balance at the point shown and pull the spring
balance. Make sure that the spring balance reads the speci-
fied value when ball stud and inner socket start to move.

Apply an axial load of 490 N (50 kg-f, 111 lb-f) to ball stud
using a dial gauge. Measure amount of stud movement, and
then make sure that the value is within the specified range.
Replace outer socket and inner socket if the measured value
is outside the standard.
ASSEMBLY
1. Apply recommended grease to teeth part and bush part of rack assembly, if necessary.
2. Apply recommended grease to back of rack assembly, if necessary.
3. Install inner socket to rack assembly. Torque to specified value while holding the flat portion of the rack
next to the inner socket using a suitable tool.
4. Apply recommended grease to inner socket. For application points, refer to PS-13, "
COMPONENT (R24K
TYPE)" .
5. Decide on the neutral position for the rack assembly.
6. Apply recommended grease to around retainer (3), then install
retainer (3), spring (4) and adjusting screw (1) to gear housing
assembly (5).
7. Apply recommended thread locking sealant to the thread (2
turns thread), and then screw in the adjusting screw (1) until it
reaches height “H” from gear housing assembly (5) measured
before disassembling.
8. Tighten lock nut to (2) the specified torque securing it to prevent
adjusting screw (1) from freewheeling condition.
9. Move rack assembly 10 strokes throughout the full stroke so that
the parts can fit with each other.
10. Using Tools A and B, measure rotating torque of pinion assem-
bly. If the measurement is outside of the specified range, read-
just pinion rotating torque. If the measurement is outside of the
specified range for readjust, replace steering gear assembly. Outer socket 0.5 mm (0.020 in) or less
Inner socket 0.2 mm (0.008 in) or less

assembly side around the center of stroke. Measure displace-
ment of rack under torsional torque of ± 7.8 N·m (0.80 kg-m, 69
in-lb), and then check if it is within the standard value. If the
measurement is outside the standard value, adjust it again. After
the readjustment, if measurement is still outside the standard
value, replace steering gear assembly.
12. Install boot to gear housing assembly and inner socket.
13. Install boot clamp (1) to boot using Tool.
NOTE:
Install large diameter side boot clamp (1) securely to boot
groove, and crimp it so as to have clearance of 3 mm (0.12 in) or
less as shown.
14. Install joint cover (1) to gear housing assembly (2).
CAUTION:
Install joint cover so that the protrusion for locating is
securely set to gear housing groove.
15. Adjust inner socket to standard length “L”, and then tighten lock
nut to the specified torque. Refer to PS-13, "
COMPONENT
(R24K TYPE)" . Check length of inner socket “L” again after
tightening lock nut. Make sure that the length is the standard.
CAUTION:
Adjust toe-in. Refer to FSU-8, "
