1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.

Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating use) to remove adhering moisture, grease and foreign materials.
3. Apply liquid gasket to the liquid gasket application surface. Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-48, "
RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .

On-Vehicle Inspection and ServiceNGS000BW
CHECKING CONDITION OF INSTALLATION

Check installation condition of steering gear assembly, front suspension, axle and steering column.

Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.

Check if the mounting bolts for steering gear assembly are loose
or not. Refer to PS-18, "
POWER STEERING GEAR AND LINK-
AGE" .
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumference when steering wheel is turned up to the point
where tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
6, "Wheel Alignment Inspection" .
1. Set vehicle to the straight direction, check if steering wheel is in the neutral position.
2. If it is not in the neutral position, remove steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock nuts of steering outer sockets, then adjust outer socket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is approximately 50 to 80 °C (122 to 176 °F).]
NOTE:
Tires need to be inflated normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360 ° from neutral position.
NOTE:
Multiply the distance L from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-30,
"On-Vehicle Inspection and Service" .
a. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to PS-13, "
COMPO-
NENTS" , FAX-4, "COMPONENTS" , FA X - 1 0 , "COMPONENTS" .

INSPECTION AFTER REMOVAL

Check if there is something wrong with jacket tube of steering column assembly and collar etc. And then if
they are damaged, replace with new one.

If vehicle has a collision light shocked, check column length “L”
as shown in the figure. Then if it is out of the specified value,
replace with new one.

Check the turning torque of steering column with preload gauge
(SST). If it is out of the specified value, repair it or replace with
new one.
INSTALLATION

Refer to PS-13, "COMPONENTS" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing steering components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .
INSPECTION AFTER INSTALLATION

Check tilt and telescopic mechanism operating range “L1 ”, “L2 ”
as shown in the figure.

Check if steering wheel operation can turn to the end of the left
and right smoothly. Steering column length “L”: 572 mm (22.52 in)
Turning torque : 0 − 0.2 N·m (0 − 0.021 kg-m, 0 − 1 in-lb)

a. To avoid damaging inner rack oil seal, wrap an OHP sheet
[approximately. 70 mm (2.76 in) × 100 mm (3.94 in) around rack
tooth. Place oil seal on sheet. Then, pull oil seal along with OHP
sheet until they pass the toothed section of rack, then remove it.
b. Insert rack oil seal (inner) to piston (rack Teflon ring) position and push retainer to adjust screw side with fingers lightly, and
then make rack move in gear housing assembly, install rack oil
seal (inner) to fit with gear housing assembly.
c. When installing outer rack oil seal, cover the end of rack with an OHP sheet [70 mm (2.76 in) × 100 mm (3.94 in)]. It will avoid
damaging rack oil seal. Then place oil seal on sheet. Pull rack oil
seal along with OHP sheet until they pass rack end. Then
remove OHP sheet.
d. Install end cover assembly to rack, move it to gear housing assembly.
5. Using a 45 mm (1.77 in) open head (suitable tool), tighten end cover assembly at the specified torque.
CAUTION:
Do not damage rack surface. If it is damaged, it may cause
oil leaks. Replace rack assembly.
6. After tightening end cover assembly, caulk cylinder at one point as shown in the figure using a punch. This will prevent end cover
from getting loose.
7. Install pinion assembly to gear housing assembly. CAUTION:
In order to protect oil seal from any damage, insert pinion
assembly out straightly.
8. Apply recommended fluid to O-ring. Install O-ring to rear cover.
9. Use a rear cover wrench (SST), install rear cover to gear hous- ing assembly.
