(4) If the piston rod moves at least 10 mm (0.39 in) in the former step, purge air from the strut.
3) Air purging procedure:
(1)
Place the strut vertically with the piston rod facing up.
(2) Fully extend the piston rod.
(3) With the piston rod fully extended, place the
--
-piston rod side down. The strut must stand ver- tically.
(4)
Fully contract the piston rod.
(5)
Repeat 3 or 4 times from the first step.
NOTE:
After completely purging air from the strut, be sure to place the strut with the piston rod facing up. If it is laid down, check for entry of air in the strut as outlined under “Checking for the presence of air”.
4)
Using a coil spring compressor, compress the coil spring.
NOTE:
Make sure that the vertical installing direction of coil spring is as shown in the figure.

A: INSPECTION
1) Take stone, glass, nail etc. off the tread groove.
2) Replace the tire:
CAUTION:
When replacing a tire, make sure to use only the same size, construction and load range as originally installed.
Avoid mixing radial, belted bias or bias tires on the vehicle.
(1) when large crack on side wall, damage or crack on tread is found.
(2) when the “tread wear indicator” appears as a solid band across the tread.

1. TIRE ROTATION
If tires are maintained at the same positions for a long period of time, uneven wear results. There- fore, they should be periodically rotated.
This lengthens service life of tires.
CAUTION:
When rotating tires, replace unevenly worn or damaged tires with new ones.

Steel
Wheel
A: REMOVAL
1)
Apply the parking brake, and position select le- ver to “P” or “LOW”.
2)
Set the shop jacks or a lift to the specified point, and support the vehicle with its wheels slightly con- tacting the floor.
3)
Loosen the wheel nuts.
4)
Raise the vehicle until its wheels take off the ground using a jack or a lift.
5) Remove the wheel nuts and wheels.
NOTE:
While removing the wheels, prevent hub bolts from damage.
NOTE:
Place the wheels with their outer sides facing up- ward to prevent wheels from damage.
B: INSTALLATION
--
I ) Attach the wheel to the hub by aligning the wheel bolt hole with the hub bolt.
2)
Temporarily attach the wheel nuts to the hub bolts. (In the case of aluminum wheel, use SUBA-
RU genuine wheel nut for aluminum wheel.)
3)
Manually tighten the nuts making sure the wheel hub hole is aligned correctly to the guide portion of hub.
4)
Tighten the wheel nuts in a diagonal selection to the specified torque. Use a wheel nut wrench.
Wheel nut tightening torque:
90
N.m (9. I kgf-m, 65.7 ff-lb)
CAUTION:
Tighten the wheel nuts in two or three steps by gradually increasing the torque and working diagonally, until the specified torque is reached. For drum brake models, excess tight- ening of wheel nuts may cause wheels to “jud- der”.
Do not depress the wrench with a foot;
Al- ways use both hands when tightening.
Make sure the bolt, nut and the nut seating surface of the wheel are free from oils.
5) If a wheel is removed for replacement or for re- pair of a puncture, retighten the wheel nuts to the specified torque after running 1,000 km (600 miles).
STEEL WHEEL

C: INSPECTION
1)
Deformation or damage on the rim can cause air leakage. Check the rim flange for deformation, crack or damage, and repair or replace as neces- sary.
2) Jack-up the vehicle until wheels clear the floor.
3) Slowly rotate the wheel to check rim “runout” us- ing a dial gauge.

-CAUTION
Aluminum wheels are easily scratched. To main- tain their appearance and safety, do the following:
1) Do not damage the aluminum wheels during re- moval, disassembly, installation, wheel balancing, etc. After removing the aluminum wheels, place them on a rubber mat, etc.
2)
While the vehicle is being driven, be careful not to ride over sharp obstacles or allow aluminum wheels to contact the shoulder of the road.
3) When installing a tire chain, be sure to install it properly not to have a slack; otherwise it may hit the wheel while driving.
4)
When washing the aluminum wheel, use neutral synthetic detergent and water. Avoid using the cleanser including abrasive, hard brushes or an automatic car washer.

B: INSPECTION
1)
Proper wheel balance may be lost if the tire is re- paired or if it wears. Check the tire for dynamic bal- ance, and repair as necessary.
2) To check for dynamic balance, use a dynamic balancer. Drive in the balance weight on both the top and rear sides of the rim.
3)
Some types of balancer can cause damage to the wheel. Use an appropriate balancer when ad- justing the wheel balance.
4)
Use genuine balance weights.

Wear working clothing, including a cap, protec- tive goggles, and protective shoes during opera- tion.
Remove contamination including dirt and corro- sion before removal, installation or disassembly.
Keep the disassembled parts in order and pro- tect them from dust or dirt.
Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary re- moval, installation, disassembly, and replacement.
Be careful not to burn your hands, because each part on the vehicle is hot after running.
Use SUBARU genuine grease etc. or the equiv- alent. Do not mix grease etc. with that of another grade or from other manufacturers.
Be sure to tighten fasteners including bolts and nuts to the specified torque.
Place shop jacks or safety stands at the specified points.
Apply grease onto sliding or revolution surfaces before installation.
Before installing O-rings or snap rings, apply suf- ficient amount of grease to avoid damage and de- formation.
Before securing a part on a vice, place cushion- ing material such as wood blocks, aluminum plate, or shop cloth between the part and the vice.

C: CAUTION
Wear working clothing, including a cap, protec- tive goggles, and protective shoes during opera- tion.
Remove contamination including dirt and corro- sion before removal, installation or disassembly.
Keep the disassembled parts in order and pro- tect them from dust or dirt.
Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary re- moval, installation, disassembly, and replacement.
Be careful not to burn your hands, because each part in the vehicle is hot after running.
Use SUBARU genuine grease etc. or the equiv- alent. Do not mix grease etc. with that of another grade or from other manufacturers.
Be sure to tighten fasteners including bolts and nuts to the specified torque.
Place shop jacks or safety stands at the specified points.
Apply grease onto sliding or revolution surfaces before installation.
Before installing O-rings or snap rings, apply suf- ficient amount of grease to avoid damage and de- formation.
Before securing a part on a vice, place cushion- ing material such as wood blocks, aluminum plate, or shop cloth between the part and the vice.
Do not put fluid on body. If the body is tainted, wash away with water.

CAUTION:
When checking operation, be sure to securely apply the hand brake.
Checking without gauges
This method cannot determine the exact portion which has failed, but it can provide a rough under- standing of the nature of the failure if checking is conducted in accordance with the following proce- dures.
Air tightness check
Start the engine, and run it for 1 to 2 minutes, then turn it off. Depress the brake pedal several times applying the same pedal force as that used in ordi- nary braking operations. The pedal stroke should be greatest on the 1 st depression, and it should be- come smaller with each successive depression. If no change occurs in the pedal height while in a de- pressed state, the brake booster is faulty.
Operation check
1)
With the engine off, depress the brake pedal several times applying the same pedal force and make sure that the pedal height does not vary with each depression of the pedal.

As engine starts, the brake pedal should move slightly toward the floor. If no change occurs in the pedal height, the brake booster is faulty.
NOTE:
If faulty, check precisely with gauges.
Loaded air tightness check
Depress the brake pedal while engine is running, and turn off the engine while the pedal is still de- pressed. Keep the pedal depressed for 30 sec- onds; if no change occurs in the pedal height, the brake booster is functioning normally; if the pedal height increases, it is faulty.
NOTE:
If faulty, check precisely with gauges.
NOTE:
In the event of defective operation, inspect the condition of the check valve and vacuum hose.
Replace them if faulty and conduct the test again.
If no improvement is observed, check precisely with gauges.

C: CAUTION
Wear working clothing, including a cap, protec- tive goggles, and protective shoes during opera- tion.
Remove contamination including dirt and corro- sion before removal, installation or disassembly.
Keep the disassembled parts in order and pro- tect them from dust or dirt.
Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary re- moval, installation, disassembly and replacement.
Be careful not to burn your hands, because each part on the vehicle is hot after running.
Use SUBARU genuine steering fluid, grease etc. or the equivalent. Do not mix steering fluid, grease etc. with that of another grade or from other manu- fact u rers.
Be sure to tighten fasteners including bolts and nuts to the specified torque.
Place shop jacks or safety stands at the specified points.
Apply steering fluid onto sliding or revolution sur- faces before installation.
Before installing O-rings or snap rings, apply suf- ficient amount of steering fluid to avoid damage and deformation.
Before securing a part on a vice, place cushion- ing material such as wood blocks, aluminum plate, or shop cloth between the part and the vice.

1) Reassembly precautions
(1) Whenever the O-rings, oil seals, and snap rings are removed, they must be replaced with new ones.
(2) Thoroughly wash the parts and allow to dry.
They must be kept free from cleaning oil and dust.
(3) Reassembly procedure must be performed in clean place. Ensure that the parts are kept away from the waste threads or other dust parti- cles.
(4) Cleaning oil tends to stay inside the front casing. Remove it completely by blowing com- pressed air.
(5) Ensure that the parts are free from rust.
(Use specified hydraulic oil for rust prevention after cleaning and drying.)
(6)
Reverse the sequence of disassembly pro- cedures.
2) Apply grease to the oil seal and inner surface of front casing (at bearing location).
CAUTION:
Make sure that the front body internal surfaces are free from damage.
3) Attach ST to front body. Using a press, install the oil seal.

*1 If the tires and/or rims are wider, the load to power steering system is the more. Accordingly, in a condition, for example before fluid warms-up, relief valve may work before maximum turning angle. In this case, steering effort may be heavy. When the mea- sured hydraulic pressure is normal, there is no abnormal thing.
*2 In cold weather, steering effort may be heavy due to increased flow resistance of cold fluid. After warming-up engine, turn the steering wheel from stop to stop several times to warm-up fluid. Then if steering effort reduces normally, there is no abnormal thing.
*3
In cold weather or with insufficient warm-up of engine, steering effort may be heavy due to excessive drop of idling when turn- ing steering wheel. In this case, it is recommended to start the vehicle with increasing engine speed than usual. Then if steering effort reduces normally, there is no abnormal thing.

GENERAL DIAGNOSTIC TABLE
POWER ASSISTED SYSTEM (POWER STEERING)
1.
NOISE AND VIBRATION
CAUTION:
Don’t keep the relief valve operated over 5 sec- onds at any time or inner parts of the oil pump may be damaged due to rapid increase of fluid temperature.
NOTE:
Grinding noise may be heard immediately after the engine start in extremely cold condition. In this case, if the noise goes off during warm-up there is no abnormal function in the system. This is due to the fluid characteristic in extremely cold condition.
Oil pump makes whine or growl noise slightly due to its mechanism. Even if the noise can be heard when steering wheel is turned at stand still there is no abnormal function in the system provid- ed that the noise eliminates when the vehicle is running.
When stopping with service brake and/or parking brake applied, power steering can be operated easily due to its light steering effort. If doing so, the disk rotates slightly and makes creaking noise. The noise is generated by creaking between the disk and pads. If the noise goes off when the brake is re- leased, there is no abnormal function in the system.
There may be a little vibration around the steer- ing devices when turning steering wheel at stand- still, even though the component parts are properly adjusted and have no defects.
Hydraulic systems are likely to generate this kind of vibration as well as working noise and fluid noise because of combined conditions, Le., road surface and tire surface, engine speed and turning speed of steering wheel, fluid temperature and braking con- dition.
This phenomena does not indicate there is some abnormal function in the system.
The vibration can be known when steering wheel is turned repeatedly at various speeds from slow to rapid step by step with parking brake applied on concrete road and in “D” range for automatic trans- mission vehicle.
