DISASSEMBLY
1. Remove cylinder tubes from gear housing assembly.
2. Remove rear cover cap from pinion assembly.
3. Using a rear cover wrench [SST: KV489Q0030] (A) to remove
rear cover from pinion assembly.
4. Remove O-ring using a flat-bladed screw driver, and pull out
rear cover.
5. 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.
6. Remove pinion assembly 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. 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].

INSPECTION AFTER DISASSEMBLY
Boot
Check boot for cracks, and replace it if a malfunction is detected.
Rack Assembly
Check rack assembly for damage or wear, and replace it if a malfunction is detected.
Pinion Assembly

Check pinion assembly for damage or wear, and replace it if a malfunction is detected.

Rotate pinion and check for torque variation or rattle, and replace it if a malfunction is detected.
Gear Housing Assembly
Check gear housing assembly for damage and scratches (inner wall). Replace if there are.
Outer Socket and Inner Socket
1. Ball joint swinging torque

Hook a spring balance at the point shown in the figure 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 steering gear assem-
bly if they are outside the standard.
2. Ball joint rotating torque

Make sure that the reading is within the following specified
range using the preload gauge [SST]. Replace outer socket if
the reading is outside the specified value.

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
N·m (0.51 kg-m, 44 in-lb) or less.
17. Apply recommended Liquid Gasket to inner socket and turn pin-
ion fully to left with inner socket installed to gear housing assembly.
18. Set dial indicator as shown in the figure. Measure vertical move-
ment of rack assembly when pinion is turned clockwise with
torque of 19.6 N·m (2.0 kg-m, 14 in-lb). Readjust adjusting
screw angle if the measured value is outside the standard.
Replace gear assembly if the measured value is still outside the
standard or adjusting screw rotating torque is 5 N·m (0.51 kg-m,
44 in-lb) or less.
19. Install large end of boot to gear housing assembly.
20. Install small end of boot to inner socket boot mounting groove.
21. Install boot clamp to boot small end.
22. Install large side of boot clamp.

Tighten large side of boot with boot clamp (stainless wire).

Wrap clamp around boot groove for two turns. Insert a flat-
bladed screwdriver in loops on both ends of wire. Twist 4 to
4.5 turns while pulling them with force of approximately 98 N
(10 kg, 22 lb).

Twist boot clamp as shown. Pay attention to relationship
between winding and twisting directions.

Twisted point of clamp is in the opposite side of adjusting
screw as shown in the figure (to prevent contact with other
parts).

Bend cut end of the wire toward rack axial as shown in the fig-
ure after twisting the wire 4 to 4.5 turns so that cut end does
not contact with boot.
CAUTION:
Keep gap from cylinder tube 5 mm (0.20 in) or more.
23. Install cylinder tubes to gear housing assembly.
24. Adjust inner socket to standard length L, and then tighten lock
nut to the specified torque. Refer to PS-20, "
COMPONENTS" .
Check length of inner socket L again after tightening lock nut .
Make sure that the length is the standard.
CAUTION:
Adjust toe-in after this procedure. Length achieved after
toe-in adjustment is not necessary the above value.

able tool) from suddenly coming off.
INSPECTION AFTER REMOVAL
Check the components for deformation, cracks and other damage. Replace if there are.
Ball Joint Inspection
Check suspension arm ball joint boot for breakage, axial play, and torque. Refer to RSU-11, "INSPECTION
AFTER REMOVAL" .
INSTALLATION
Wheel Hub and Bearing Assembly

Installation is the reverse order of the removal. For tightening torque, refer to RAX-3, "COMPONENT" .
NOTE:
Do not reuse non-reusable parts.

Assemble disc rotor and wheel hub and bearing assembly by
aligning each matching mark as shown in the figure when install-
ing disc rotor.
NOTE:
Refer to BR-33, "
REAR DISC BRAKE" for assembly when
removing disc rotor without matching mark.

Check wheel sensor harness for proper connection. Refer to
BRC-33, "
WHEEL SENSORS" .

Adjust neutral position of steering angle sensor after checking
the wheel alignment for the models with VDC. Refer to BRC-40,
"Adjustment of Steering Angle Sensor Neutral Position" .
