1996 SUBARU LEGACY check oil

C: INSPECTION
Check the disassembled parts for cracks, damage and
wear, and replace with new parts if defective.
G4M0508
1. DAMPER STRUT
1) Check for oil leakage.
2) Move the piston rod up and down to check its operates
smoothly without any binding.
3) Play of piston rod
Measure the play as follows:
Fix outer shell and fully extend the rod. Set a dial gauge at
the end of the rod: L [10 mm (0.39 in)], then apply a force
of W [20 N (2 kg, 4 lb)] to threaded portion. With the force
of 20 N (2 kg, 4 lb) applied, read dial gauge indication: P
1.
Apply a force of 20 N (2 kg, 4 lb) in the opposite direction
of“W”, then read dial gauge indication: P
2. The free play
is determined by the following equation:
Play = P
1,P2
Limit of play:
Less than 0.8 mm (0.031 in)
If the play is greater, replace the strut with new one.
2. STRUT MOUNT
Check rubber part for wear, cracks and deterioration, and
replace it with new one if defective.
3. DUST COVER
If any cracks or damage are found, replace it with new one.
4. COIL SPRING
When vehicle posture is uneven, although there are no
considerable reasons like tire puncture, uneven loading,
etc., check coil spring and spring seats for cracks,
deformation, etc., and replace it with a new one if defective.
5. HELPER
Replace it with new one if cracked or damaged.

4. Front Strut

D: ASSEMBLY
1) Before installing coil spring, strut mount, etc., on the
strut, check for the presence of air in the dampening force
generating mechanism of the strut since air prevents
proper dampening force from being produced.
2) Checking for the presence of air
(1) Place the strut vertically with the piston rod facing
upward.
(2) Move the piston rod to the center of its entire
stroke.
(3) While holding the piston rod end with finger-tips,
move the rod up and down.
(4) If the piston rod moves at least 10 mm (0.39 in) in
step (3), purge air from the strut.
3) Air purging procedure
(1) Place the strut vertically with the piston rod facing
upward.
(2) Fully extend the piston rod.
(3) With the piston rod fully extended, place the piston
rod side down. The strut must stand vertically.
(4) Fully contract the piston rod.
(5) Repeat 3 or 4 times steps (1) through (4) above.
NOTE:
After completely purging air from the strut, be sure to place
the strut with the piston rod facing upward. If it is laid down,
check for entry of air in the strut as outlined under item 2)
above.
B4M0568A
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 figure.
G4M0510
5) Set the coil spring correctly so that its end face fits well
into the spring seat as shown.
6) Install helper and dust cover to the piston rod.

10. Wheel Balancing
1) Proper wheel balance may be lost if the tire is repaired
or if it wears. Check the tire for dynamic balance, 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 adjusting the
wheel balance.
4) Use genuine balance weights.
Service limit: A
Weight for steel wheel;
1.6—2.0 mm (0.063—0.079 in)
Weight for aluminum wheel;
4.6—5.4 mm (0.181—0.213 in)
CAUTION:
55 g (1.94 oz) weight used with aluminum wheel is
not available.
Balance weights are available for use with any of 14-
to 15-inch wheels.
11. Installation of Wheel Assembly to
Vehicle
1) 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 SUBARU 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:
88±10 N⋅m (9±1 kg-m, 65±7 ft-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 tightening of wheel nuts
may cause wheels to “judder”.
Do not depress the wrench with a foot; Always 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 repair of a
puncture, retighten the wheel nuts to the specified torque
after running 1,000 km (600 miles).
