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.
• When tightening bolt (intermediate shaft lower side), tight en 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. (D o 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-III to ensure correct opera-
tion. Refer to STC-8, "
CONSULT-III Function".

CAUTION:
Clean steering gear assembly with kerosene before disassembling.
DISASSEMBLY
1. Loosen outer socket lock nut, and then remove outer socket from inner socket.
2. Remove boot clamp, and then remove boot from inner socket.
CAUTION:
Do not damage inner socket and gear housin g assembly when removing boot. Inner socket and
gear housing assembly must be replaced if inne r socket and gear housing assembly are damaged
because it may allow foreign material to enter.
3. Remove inner socket from rack assembly while holding the flat portion of the rack next to the inner socket using a suitable tool.

4. Measure adjusting screw height “H”, and loosen lock nut (2).
5. Remove adjusting screw (1), retainer (3) and spring (4) from gear housing assembly (5).
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 scra tches. Replace steering gear as necessary.
Outer Socket and Inner Socket
1. Check ball joint swinging torque.
• Hook Tool at the point shown and pull the spring balance.
Make sure that the spring balance reads the specified value
when ball stud and inner socket start to move. Replace outer
socket and inner socket if they are outside the standard.
2. Ball joint axial end play • Apply an axial load of 490 N (50 kg-f, 111 lb-f) to ball stud.
Measure amount of stud movement using a dial gauge, 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 racknext 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 out side 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” : Refer to
PS-21, "
