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 "COMPONENT".
• When tightening bolt (intermediate shaft lower side), tighten it by hand first, and make sure there is no feel-
ing 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 opera-
tion. Refer to STC-11, "
CONSULT-III Function (EPS)". Steering column

• 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 "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

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.
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 "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-6, "
Wheel Alignment Inspec-
tion". Length achieved after toe-in adjustment is not neces-
sarily the above value.Standard value : Less than 0.1 mm (0.004 in)
