●Start engine. With engine at idle, turn steering wheel from stop
to stop and measure steering angles.
●If angles are outside specification, measure rack stroke.
●If rack stroke is outside of specification, disassemble steering
gear to check rack stroke.
●Steering angles are not adjustable. If any of steering angles is different from specified value, check steer-
ing gear, the column and the front suspension components for wear or damage. If any abnormality exists,
replace the malfunctioning parts.
Removal and InstallationEGS0004F
REMOVAL
1. Remove air bag module. Refer to SRS-29, "DRIVER AIR BAG MODULE" .
2. Remove horn connector.
3. Remove steering wheel mounting nut and paint mating marks on steering wheel body and top of column
shaft.
4. Using a steering wheel puller, remove steering wheel.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.
NOTE:
●When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned.
This will omit neutral position alignment procedure during spiral cable installation.
●Neutral position (refer to figure)... Gently turn spiral cable clock-
wise until it comes to the stop. Then turn it counter clockwise
(approximately 3.0 turns) until centering mark is aligned with
adjustment mark. (Service part is fixed in neutral position with
stopper. It can be installed onto steering wheel without align-
ment once stopper is removed.)
CAUTION:
●Place steering wheel as follows: Front wheels in straight-
ahead position. R mark on the cancel claw faces down. 3
bosses align with 3 holes behind steering wheel assembly.
Check that spiral cable is placed in neutral position and that
locating pin on the left of the spiral cable is aligned with the
locating pinhole behind the steering wheel assembly.
●Do not rotate spiral cable more than necessary. Do not tighten them excessively. (The cable may
be torn off.)
●After installation, check system for proper operation by observing air bag warning lamp.
●If air bag indicator indicates any abnormal condition, use self-diagnosis function or CONSULT to
reset or cancel memory.Inner wheel Minimum : 36°

On-Vehicle Inspection and ServiceEGS000AF
OIL PUMP PULLEY HYDRAULIC PRESSURE INSPECTION
Before starting following procedure, check tension of belt.
1. Raise vehicle. Connect oil pressure gauge between oil pump
discharge connector and high pressure hose. Then bleed the
hydraulic circuit.
2. Start engine. Run engine until oil temperature reaches 50°C -
80°C (122 - 176°F)
CAUTION:
●Leave valve of hydraulic pressure gauge fully open while
starting and running engine. If engine is started with
valve closed, hydraulic pressure in oil pump goes up.
This will relief pressure along with abnormal increase of
oil temperature.
●Care must be taken to keep hose clear of belt and other parts when engine is started.
3. Fully close hydraulic pressure gauge valve with engine at idle. Measure relief pressure.
4. After measurement, open valve slowly.
CAUTION:
Never keep valve closed for 15 seconds or longer.
●If relief pressure is outside specification, disassemble and service oil pump. Refer to PS-25, "Disas-
sembly and Assembly(QR20DE and QR25DE engine models)" .
5. After inspection, remove oil pressure gauge from hydraulic circuit. Add fluid. Be sure to bleed the system
completely. Refer to PS-5, "
Bleeding Hydraulic System"
Removal and Installation (QR20DE and QR25DE engine models)EGS000AG
REMOVAL
1. Loosen adjusting screw and oil pump mounting bolt. Then, remove belt.
2. Remove union bolt and hose for oil pump.
3. Remove oil pump bracket attaching bolt.
4. Remove oil pump from vehicle.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.
●After installation, adjust belt tension. Refer to EM-12, "DRIVE BELTS" .
●After installation, be sure to bleed system. Refer to PS-5, "Bleeding Hydraulic System" . Relief pressure specification:
8,140 - 8,728 kPa (81.4 - 87.3 bar, 83 - 89 kg/cm

●When installing rubber parts, final tightening must be carried out under unladen condition* with tires on
ground.
●Oil will shorten the life of rubber bushes. Be sure to wipe off any spilled oil.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
●After installing removed suspension parts, check wheel alignment and adjust if necessary.
Observe the following precautions when disassembling and servicing drive shaft.
●Perform work in a location which is as dust-free and dirt-free as possible.
●Before disassembling and servicing, clean the outside of parts.
●Disassembly and service location must be taken to prevent the entry of foreign objects.
●Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.
●Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.
●Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.

FRONT DRIVE SHAFT
●When the drive shafts listed below have been removed, check that a circular clip is attached to the end.
×: Applicable
–: Not applicable
●Remove installation bolt from right-side drive shaft support bearing bracket. Then remove bracket from
engine.
●Remove installation bolt from right-side drive shaft and remove drive shaft from side shaft.
INSPECTION AFTER REMOVAL
●Move joint in up/down, left/right, and axial directions. Check for
motion that is not smooth and for significant looseness.
●Check for cracking and damage of boots, and for grease leak-
age.
INSTALLATION
●Install support bearing bracket onto engine and tighten installation bolts to specified torque.
●Install drive shaft to side shaft and tighten installation bolts to specified torque.
1. In order to prevent damage to differential side oil seal, first fit a
protector onto oil seal before inserting drive shaft. Slide drive
shaft slide joint and tap with a hammer to install securely.
CAUTION:
Be sure to check that circular clip is securely fastened.
2. Insert drive shaft into steering knuckle. Install lock nut and then
temporarily tighten lock nuts.
3. Install installation bolt for steering knuckle and strut.
4. Use lock plate to fix brake hose to strut.
5. Install tie rod to steering knuckle.
6. Install ABS wheel speed sensor.
7. Tighten lock nuts to specified torque.
8. Install cotter pin.
CAUTION:
Discard the old cotter pin; replace with a new one.
