CAUTION:
Spiral cable may be cut if steering wheel turns while separating steering column assembly and steer-
ing gear assembly. Be sure to secure steer ing wheel using string to avoid turning.
REMOVAL
1. Remove front suspension member. Refer to FSU-11, "Removal and Installation".
2. 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 condition, binding, noise or excessive steering effort.

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 remove 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 foreign 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.

4. Measure adjusting screw height “H”, and loosen lock nut (2).
5. Remove adjusting screw (1), retainer (3) and spring (4) fromgear 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 variati on 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.
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.

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)

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. 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-7, "
Wheel Alignment Inspec-
tion". Length achieved after toe-in adjustment is not neces-
sarily the above value. Tool number : KV40107300 ( — )
