14. Push rack oil seal inside with a 29 mm (1.14 in) socket and an
extension bar to push out rack oil seal (inner side) from gear
housing assembly.
CAUTION:
Do not damage gear housing assembly and cylinder inner
wall. Gear housing assembly must be replaced if damaged
because it may cause fluid leakage.
INSPECTION AFTER DISASSEMBLY
Boot
Check boot for cracks, and replace it if a malfunction is detected.
Rack Assembly
Check rack for damage or wear, and replace it if a malfunction is detected.
Gear-Sub Assembly

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

Rotate gear-sub assembly 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.
3. Ball joint axial end play

Apply an axial load of 490 N (50 kg, 111 lb) to ball stud using a
dial gauge. Measure amount of stud movement, and then
make sure that the value is within the following specified
range. Replace outer socket and inner socket if the measured
value is outside the standard.

12. Apply recommended thread locking sealant 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 N·m (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
N·m (0.51 kg-m, 44 in-lb) or less.
17. Apply recommended liquid gasket 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 N·m (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 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 (1) as shown in the figure (to prevent contact with other
parts).

Bent 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-21, "
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.
