INSPECTION AFTER REMOVAL
lCheck component parts for damage or other malfunctions. Replace if there are.
lMeasure the length “L” as shown in the figure if vehicle has been
involved in a minor collision. Replace steering column assembly
if outside the standard.
lMeasure steering column assembly rotating torque using pre-
load gauge [SST: ST3127S000]. Replace steering column
assembly if outside the standard.
INSTALLATION
lInstallation is the reverse order of removal. For tightening torque, refer toPS-11, "COMPONENT".
lWhen installing lower shaft to steering gear assembly, follow the procedure listed below.
–Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn pinion assembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.
–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.
–Install slit part of lower shaft (C) aligning with the projection (A)
of rear cover cap (1). Make sure that the slit part of lower shaft
(C) is aligned with both the projection (A) of rear cover cap (1)
and the marking position (B) of gear housing assembly.Steering column length “L” : 423.1 mm (16.66 in)

then measure the intermediate position of the distance.
–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.
–Install slit part of lower shaft (C) aligning with the projection (A)
of rear cover cap (1). Make sure that the slit part of lower shaft
(C) is aligned with both the projection (A) of rear cover cap (1)
and the marking position (B) of gear housing assembly.
lAfter installation, bleed air from the steering hydraulic system.
Refer toPS-6, "
Air Bleeding Hydraulic System".
lPerform final tightening of nuts and bolts on each part under
unladen conditions with tyres on level ground when removing
steering gear assembly. Check wheel alignment. Refer toFSU-
7, "Front Wheel Alignment".
INSPECTION AFTER INSTALLATION
Make sure that steering wheel operates smoothly by turning several times from full left stop to full right stop.

11. Remove end cover assembly with a 45 mm (1.77 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(104°F) with a
dryer, and remove rack Teflon ring and O-ring B from rack
assembly.
CAUTION:
Do not damage rack assembly. Rack assembly must be
replaced if damaged because it may cause fluid leakage.
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.
Pinion Assembly
lCheck pinion assembly for damage or wear, and replace it if a malfunction is detected.
lRotate 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.

lHook 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
lMake 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
lApply 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.

b. Insert rack oil seal (inner) into rack assembly piston (rack Teflon
ring).
c. Push retainer to adjusting screw side by hand, and move the
rack assembly inside the gear housing assembly so that the
rack oil seal (inner) can be pressed against the gear housing
assembly.
d. Wrap an OHP sheet [approximately 70 mm (2.76 in)´100 mm
(3.94 in)]. Around the edge to avoid damaging rack oil seal
(outer). Install rack oil seal over sheet. Then, pull oil seal along
with OHP sheet until they pass rack edge, and remove OHP
sheet.
e. Install end cover assembly to rack edge, and move rack oil seal
(outer) until it contacts with gear housing assembly.
5. Tighten end cover assembly to specified torque using a 45 mm
(1.77 in) open head (suitable tool).
CAUTION:
Do not damage rack assembly. Replace it if damaged
because it may cause fluid leakage.
6. Crimp gear housing assembly at one point using a punch as
shown in the figure so as to prevent end cover assembly from
getting loose after tightening end cover assembly.
7. Install pinion assembly to gear housing assembly.
CAUTION:
In order to protect rack oil seal from any damage, insert pin-
ion assembly out straightly.
8. Apply recommended fluid to O-ring A. Install O-ring A to rear
cover.
9. Using a rear cover wrench [SST: KV489Q0030] (A), install rear
cover to gear housing assembly.
