CONDITION OF INSTALLATION
• Check installation condition of power steering gear assembly, front suspension, front drive shaft and steering
column.
• Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
• Verify that the power steering gear nuts are tightened to specification. Refer to ST-36, "Exploded View"
.
STEERING WHEEL PLAY
1. Turn tires straight ahead, start engine, then turn steer ing wheel to the left and right lightly. Measure steer-
ing wheel movement on the outer circumference of the steering wheel when it is turned to the point where
tires start moving.
NEUTRAL POSITION ON STEERING WHEEL
• Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
25, "Wheel Alignment (Unladen*1)".
1. Turn tires straight ahead, check if st eering wheel is in the neutral position.
2. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot be attained by repositi oning the steering wheel two teeth or less on steering
stem, loosen tie-rod lock nuts of power steering gear outer sockets, then adjust tie-rods by the same
amount in the opposite direction.
STEERING WHEEL TURNING FORCE
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to operating temperature.
4. Verify that the tires are inflated to the specified pressure. Refer to WT-60, "Tire"
.
5. Check steering wheel turning force using Tool when steering wheel has been turned 360 ° from the neutral position.
6. If steering wheel turning force is out of specification, inspect steering column. Refer to ST-18, "Inspection"
.
7. If steering column meets specification, inspect steering gear. Refer to ST-20, "Inspection"
.

RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal be fore starting the following procedure.
1. Connect the Tool between oil pump discharge connector and high-pressure hose. Bleed air from the hydraulic circuit while
opening valve fully. Refer to ST-30, "Air Bleeding Hydraulic Sys-
tem".
2. Start engine. Run engine until power steering fluid temperature reaches 50 ° - 80 °C (122 ° - 176 °F).
CAUTION:
• Leave the valve of the hydraulic pressure gauge fully open while starting and ru nning engine. If engine is
started with the valve closed, th e hydraulic pressure in oil
pump goes up to the relief pressure along with unusual
increase of fluid temperature.
• Be sure to keep hose clear of belts and other parts when engine is started.
3. Fully close the Tool valve with engine at idle and measure the relief oil pressure.
CAUTION:
Do not keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Replace oil pump if the relief oil pressure is outside the standard.
5. After inspection, disconnect the Tool from hydraul ic circuit, then add fluid and bleed air. Refer to ST-30,
"Air Bleeding Hydraulic System".

Draining and RefillingINFOID:0000000009461266
DRAINING
1. Disconnect the high and low pressure piping from power steering gear.
2. Drain power steering fluid into a suitable container.
REFILLING
1. Fill power steering reservoir while checking power steering fluid level.
2. Bleed air from power steering hydraulic system. Refer to ST-30, "Air Bleeding Hydraulic System"
.
3. Check for power steering fluid leaks.
Air Bleeding Hydraulic SystemINFOID:0000000009461267
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, excessive noise in the power steering oil pump will be present.
1. Make sure engine is off.
2. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles are no longer being generated in the reservoir.
3. When the power steering fluid level lowers, refill the reservoir. CAUTION:
Do not allow the power steerin g fluid level to drop below
the hatching area.
4. Repeat steps one and two until the power steering fluid level stabilizes.
5. Start the engine and run at idle.
6. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles or fluid discoloration are no longer being generated in the reservoir.
7. When the power steering fluid level lowers, refill the reservoir.
8. Stop the engine.
9. Verify proper power steering fluid level. Power steering fluid level should be between the hatching area of the indicator on
the power steering reservoir tank cap.

6. Remove front exhaust tube. Refer to EX-5, "Exploded View" (QR25DE), EX-10, "Exploded View"
(VQ35DE).
7. Disconnect the high and low pressure piping from the steering gear assembly.
8. Remove steering hydraulic piping bracket bolts from the steering gear assembly.
9. Remove bolts and nuts of steering gear assembly, then remove steering gear assembly from vehicle.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
Do not reuse O-rings or copper sealing washers.
• When installing lower joint 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 gear-sub a ssembly and measure the distance of inner socket, and
then measure the intermediat e position of the distance.
- Align rear cover cap projection (A) with the marking position (B) of
gear housing assembly.
- Install slit part of lower joint (C) aligning with the projection (A) of
rear cover cap (1). Make sure that the slit part of lower joint (C) is
aligned with both the projection (A) of rear cover cap (1) and the
marking position (B) of gear housing assembly.
• After installation, bleed air from the steering hydraulic system. Refer to ST-15, "Inspection"
.
• Perform final tightening of nuts and bolts on each part under
unladen conditions with tires on level ground when removing steer-
ing gear assembly.
• Check wheel alignment. Refer to FSU-7, "Inspection and Adjust-
ment".
• Perform neutral position steering angle adjustment. Refer to BRC-58, "Work Procedure"
.
