On-Vehicle Inspection and ServiceINFOID:0000000001282496
CHECKING CONDITION OF INSTALLATION
 Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
 Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
 Check steering gear assembly mounting bolts and nuts for looseness. Refer to ST-12, "
Removal and Instal-
lation" .
CHECKING STEERING WHEEL PLAY
 Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on the
outer circumference.
 When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
 Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the
correct position.
 Perform neutral position inspection after wheel alignment. Refer to SR-2, "
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"" .
 Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
 Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if steer-
ing wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Check steering wheel turning force when steering wheel has
been turned 360° from neutral position using suitable tool as
shown.
4. If steering wheel turning force is out of the specification, refer to
STC-3, "
Work Flow" .
CHECKING FRONT WHEEL TURNING ANGLE
Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)
Steering wheel
turning force: Less than 36 N (3.7 kg-f, 8.2 lb-f)

REMOVAL
NOTE:
When reconnecting spiral cable, secure cable with a tape so that case and rotating part keep aligned. This will
omit neutral position alignment procedure during spiral cable installation.
1. Set front wheels to straight-ahead position.
2. Remove driver air bag module. Refer to SR-4, "
Removal and Installation" .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
Do not run spiral cable idle needlessly. And do not turn it more than necessary (or it leads to discon-
nection of the cable).
NOTE:
 The neutral position is set as follows.
Turn the spiral cable clockwise to the end position. Then turn it
counterclockwise (about 2 and half turns) and stop turning at the
point on which the stopper insertion holes are in the same position
(B). The service part is installed in the neutral position by the stop-
per and can be set without adjusting after the stopper is removed.
 Adjust the spiral cable locating pin (B) to the steering wheel locat-
ing pin hole (C).

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 small diamter boot clamp.
14. Install large diameter boot clamp (1) to boot using Tool.
NOTE:
Install large diameter 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.
15. 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.
16. 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-17, "
Wheel Alignment
(Unladen*)". Length achieved after toe-in adjustment is not
necessarily the above value.Standard value : Less than 0.1 mm (0.004 in)

 Check if the connection of steering 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 suspension 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 disconnecting 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 ignition switch is turned “OFF”.
 When connecting or disconnecting 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 inspection and make sure whether EPS
control unit functions properly or not. Refer to STC-22, "
EPS
Control Unit Input/Output Signal Reference Value".

TRANSAXLE ASSEMBLY
When installing the torque converter to the transaxle measure dis-
tance A.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
 When replacing an engine or transmission you must make sure any dowels are installed correctly
during re-assembly.
 Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.
 Do not reuse O-rings and copper washers. Refer to TM-210, "
Exploded View".
 When turning crankshaft, turn it clockwise as viewed from the front of the engine.
 When tightening the bolts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-50, "
Removal and Installa-
tion".
 After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.
 When installing the transaxle to the engine, align the matching mark on the drive plate with the matching
mark on the torque converter.
 When securing the transaxle assembly to the engine, attach the
bolts in accordance with the following standard.
(A): A/T to engine
(B): Engine to A/T
 Align the positions for the bolts on drive plate with those of the
torque converter, and temporarily tighten bolts. Then, tighten bolts
to the specified torque.
 After completing installation, check for A/T fluid leakage, A/T fluid
level and A/T positions. Refer to TM-171, "
Checking A/T Fluid" and
TM-204, "
Checking of A/T Position". Dimension A: 16.2 mm (0.638 in) or more
