EX-4
EXHAUST SYSTEM


Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.

Install seal bearings at exhaust front tube and main muffler as follows.
CAUTION:
Do not mix the bolt and spring for seal bearing as the dimension is different for each seal bearing.
Exhaust Front Tube Side (QR20DE and QR25DE)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with
exhaust front tube flange.
Main Muffler Side (QR20DE, QR25DE and YD22DDTi)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with main
muffler flange.
INSPECTION AFTER INSTALLATION

With the engine running, check exhaust tube joints for gas leakage and unusual noises.

Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

STEERING WHEEL

STEERING WHEELPFP:48430
On-Vehicle Inspection and ServiceEGS001BY
CHECKING CONDITION OF INSTALLATION

Check installation conditions 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 steering gear assembly mounting bolts and nut for looseness. Refer to PS-16, "COMPONENT" .
CHECKING STEERING WHEEL PLAY

Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on
the outer circumference.

When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL

Make sure that steering gear assembly, steering column and steering wheel are installed in the correct
position.

Perform neutral position inspection after wheel alignment. Refer to FSU-6, "Wheel Alignment" .

Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.

Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.
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).]
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 scale to the
center of steering wheel by the measurement value with a
spring scale.

Perform the following manner when the guideline value is
hard to be measured.
a. Park vehicle on a level and dry surface, set parking brake.
b. Remove driver air bag module. Refer to SRS-30, "
DRIVER AIR BAG MODULE" .
c. Start engine at idle, then check steering wheel turning force with
pre-load gauge [SST].
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-27,
"OIL PUMP PULLEY HYDRAULIC PRESSURE INSPECTION" .
a. Disconnect lower shaft and steering knuckle from steering gear
assembly. Refer to FAX-7, "
Removal and Installation" , PS-11,
"COMPONENT" . Steering wheel axial end play : 0 mm (0 in)

Gear Housing Assembly
Check gear housing assembly for damage and scratches (inner wall). Replace if there are.
Outer Socket and Inner Socket
1. 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. 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. Axial end play

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

INSPECTION AFTER REMOVAL
Check regulator assembly for the following items. If a malfunction is
detected, replace or grease it.

Gear wear

Regulator deformation

Spring damage

Grease condition for each sliding part
The arrows in the figure show body grease application points of the
grease “Dow Corning Moly Coat SK 623” or equivalent.
FITTING INSPECTION

Check that glass is securely fit into glass run groove.

While raising and lowering the window, check for abnormal operation.

Lower the glass slightly [approx. 10 to 20 mm (0.39 to 0.79 in)], and check that the clearance to the sash
is parallel. If the clearance between the glass and sash is not parallel, loosen the regulator mounting bolts,
guide rail mounting bolts, and glass & carrier plate mounting bolts to correct the glass position.
