COMPONENT
CAUTION:
• Do not allow axial impact to steering colu mn assembly during removal and installation.
• Steering column must be kept at maximum tilt up position during removal and installation. Do not
operate tilt mechanism while steeri ng column is out of the vehicle.
• Put matching mark on intermediate shaft and st eering column assembly before removing intermedi-
ate shaft.
• When steering wheel is turned re peatedly 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 assembly
from vehicle.
• Do not put steering column assem bly near the things that generate excessive magnetic force.
• Steering column assembly (with motor, reduc tion gear, sensor) cannot be disassembled.
• Any time the ignition switch h as been removed and installed, the keys must be re-registered in the
BCM. Refer to CONSULT–III ope ration manual IVIS/NVIS.
REMOVAL 1. Set front wheels to straight ahead-position.

5. Loosen steering outer socket (1) mounting nut.
6. Remove steering outer socket (1) from steering knuckle (2) so as not to damage ball joint boot (3) using the ball joint remover
(suitable tool).
CAUTION:
Temporarily tighten the nut to prevent damage to threads
and to prevent the ball joint remover (suitable tool) from
suddenly coming off.
7. Remove front suspension member. Refer to FSU-11, " Removal and Installation " .
8. Remove mounting bolts and nuts of steering gear assembly.
INSTALLATION
Installation is in the reverse order of removal.
• Clean mounting surface on the body side of lower dash seal when installing steering gear assembly.
• Check wheel alignment under unladen conditions with tires on level ground. Refer to FSU-7, " Wheel Align-
ment Inspection " .

INSPECTION AFTER INSTALLATION
Rotate steering wheel to check for decentered conditi on, binding, noise or excessive steering effort.
Disassembly and Assembly INFOID:0000000004305935
COMPONENT (R24K TYPE)
CAUTION:
Clean steering gear assembly with kerosene before disassembling.
DISASSEMBLY 1. Loosen outer socket lock nut, and then re move outer socket from inner socket.
2. Remove boot clamp, and then re move boot from inner socket.
CAUTION:
Do not damage inner socket an d gear housing assembly when re moving boot. Inner socket and
gear housing assembly must be replaced if inne r socket and gear housing assembly are damaged
because it may allow fore ign material to enter.
3. Remove inner socket from rack assembly while holdi ng the flat portion of the rack next to the inner socket
using a suitable tool.

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.
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.
11. Set dial gauge to the back of rack assembly on the pinion 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. Rack stroke “L” : 65.0 mm (2.559 in)
