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.

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, "
Steering Gear".

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 ( — )

Service Notice or Precaution for EPS SystemINFOID:0000000005931271
CAUTION:
Check or confirm the following item wh en performing the trouble diagnosis.
• Check any possible causes by interviewing the symptom and it’s condition from the customer if any
malfunction, such as EPS warn ing lamp turns ON, occurs.
• Check if air pressure and size of tires are proper, the specified part is used for the steering wheel,
and control unit is genuine part.
• Check if the connection of steer ing column assembly and steering gear assembly is proper (there is
not looseness of mounting bolts, damage of rods, boots or sealants, and leakage of grease, etc).
• Check if the wheel alignment is adjusted properly.
• Check if there is any damage or modification to su spension or body resulting in increased weight or
altered ground clearance.
• Check if installation conditions of each link and suspension are proper.
• Check if the battery voltage is proper
• Check connection conditions of each connector are proper.
• Before connecting or disconnect ing the EPS control unit har-
ness connector, turn ignition switch “OFF” and disconnect
battery ground cable. Because battery voltage is applied to
EPS control unit even if igniti on switch is turned “OFF”.
• When connecting or disconnect ing pin connectors into or
from EPS control unit, take care not to damage pin terminals
(bend or break).
When connecting pin connectors, make sure that there are no
bends or breaks on EPS control unit pin terminal.
• Before replacing EPS control unit, perform EPS control unit input/output signal inspectio n and make sure whether EPS
control unit functions properly or not. Refer to STC-20, "
Ref-
erence Value".
