4. CHECK HEIGHT SENSOR SIGNAL AND AIMING MOTOR DRIVE SIGNAL
Remove height sensor link bracket mounting nuts (rear stabilizer side). For details, refer to LT- 1 9 2 , "
Removal
and Installation of Height Sensor" . Change sensor angle from the basic point of sensor angle 0 (standard
position) and check “HI SEN OTP RR” and “LEV ACTR VLTG” of “Data Monitor”.
With 18-inch wheel
NOTE:
1. Reference value. The value can be different from that of sensor angle and HI SEN OTP RR of maximum/minimum angle of auto
aiming operation depending on LEVELIZER ADJUSTMENT state.
2. Reference value. Approx.
1.5 V from the LEVELIZER ADJUSTMENT value.
With 19-inch wheel
NOTE:
1. Reference value. The value can be different from that of sensor angle and HI SEN OTP RR of maximum/minimum angle of auto
aiming operation depending on LEVELIZER ADJUSTMENT state.
2. Reference value. Approx.
1.2 V from LEVELIZER ADJUSTMENT value.

When approx. 4.5 V or 0.5 V is not displayed on “HI SEN OTP RR” screen with sensor angle
approx. 45
or 45, check connector for connection, bend and loose fit. If it is normal, replace
height sensor. Refer to LT- 1 9 2 , "
Removal and Installation of Height Sensor" .
When “HI SEN OTP RR” value is normal but “LEV ACTR VLTG” value differs from maximum/
minimum angle of auto aiming operation, replace AFS control unit. Refer to LT- 1 9 1 , "
Removal
and Installation of AFS Control Unit" .
When “LEV ACTR VLTG” value is normal but operation range is irregular, check aiming motor

DISASSEMBLY
1. Remove fixing bolts of EPS solenoid valve, and then remove EPS solenoid valve from gear-sub assembly.
2. Remove cylinder tubes from gear housing assembly.
3. Remove rear cover cap from gear-sub assembly.
4. Measure adjusting screw height “H”, and loosen adjusting
screw.
CAUTION:
Do not loosen adjusting screw 2 turns or more.
Replace steering gear assembly if adjusting screw is
loosened 2 turns or more and it is removed.
5. Remove fixing bolts of gear-sub assembly, and then remove
gear-sub assembly from gear housing assembly.
6. Remove O-ring from gear housing assembly.
7. Loosen outer socket lock nut, and remove outer socket.
8. Remove boot clamp, and then remove boot from inner socket.
CAUTION:
Do not damage inner socket and gear housing assembly when removing boot. Inner socket and
gear housing assembly must be replaced if inner socket and gear housing assembly are damaged
because it may cause foreign material interfusion.
9. Remove inner socket from gear housing assembly.
10. Drill out the clinching part of gear housing assembly (end cover
assembly side) outer rim with a 3 mm (0.12 in) drill bit. [Drill for
approximately 1.5 mm (0.059 in) depth.]
11. Remove end cover assembly with a 36 mm (1.42 in) open head
(suitable tool).
CAUTION:
Do not damage rack assembly surface when removing.
Rack assembly must be replaced if damaged because it
may cause fluid leakage.
12. Pull rack assembly together with rack oil seal (outer side) out
from gear housing assembly.
CAUTION:
Do not damage cylinder inner wall when removing rack
assembly. Gear housing assembly must be replaced if dam-
aged because it may cause fluid leakage.
13. Heat rack Teflon ring to approximately 40
C (104F) with a
dryer, and remove rack Teflon ring and O-ring from rack assem-
bly.
CAUTION:
Do not damage rack assembly. Rack assembly must be
replaced if damaged because it may cause fluid leakage.

to the thread (2 turns thread), and then screw in the adjusting
screw until it reaches height “H” from gear housing assembly
measured before disassembling.
13. Move rack assembly 10 strokes throughout the full stroke so that
the parts can fit with each other.
14. Measure pinion rotating torque within
180 of neutral position
of the rack assembly using the preload gauge [SST] and preload
adapter [SST]. Stop the gear at the point where highest torque is
read.
15. Loosen adjusting screw and retighten to 5.4 Nꞏm (0.55 kg-m, 48
in-lb), and then loosen by 20 to 40
.
16. Measure pinion rotating torque using the preload adapter [SST]
and preload gauge [SST] to make sure that the measured value
is within the standard. Readjust if the value is outside the stan-
dard. Replace steering gear assembly if the value is outside the
standard after readjusting or adjusting screw rotating torque is 5
Nꞏm (0.51 kg-m, 44 in-lb) or less.
17. Apply Genuine Liquid Gasket, Three Bound 1111B or equivalent to inner socket and turn pinion fully to left
with inner socket installed to gear housing assembly.
18. Set dial gauge as shown in the figure. Measure vertical move-
ment of rack assembly when pinion is turned clockwise with
torque of 19.6 Nꞏm (2.0 kg-m, 14 ft-lb). Readjust adjusting screw
angle if the measured value is outside the standard. Replace
steering gear assembly if the measured value is still outside the
standard or adjusting screw rotating torque is 5 Nꞏm (0.51 kg-m,
44 in-lb) or less.

4. If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height (dimension X).
If the tooth contact is near the face (face contact), or near the
heel (heel contact), thicken pinion height adjusting washers to
move drive pinion closer to drive gear.
Refer to RFD-38, "
Pinion Height Adjusting Washer" .
If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thin pinion height adjusting washers to move
drive pinion farther from drive gear.
Refer to RFD-38, "
Pinion Height Adjusting Washer" .
Backlash
1. Remove rear cover. Refer to RFD-22, "Differential Assembly" .
2. Fit a dial indicator to the drive gear face to measure the back-
lash.
If the backlash is outside of the specified value, change the
thickness of side bearing adjusting washer.
CAUTION:
Do not change the total amount of washers as it will change the bearing preload.

Backlash: 0.10 - 0.15 mm (0.0039 - 0.0059 in)
When the backlash is large:
Make drive gear back side adjusting washer thicker,
and drive gear tooth side adjusting washer thinner by
the same amount. Refer to RFD-38, "
Side Bearing
Adjusting Washer" .
When the backlash is small:
Make drive gear back side adjusting washer thinner,
and drive gear tooth side adjusting washer thicker by
the same amount. Refer to RFD-38, "
