1996 SUBARU LEGACY Coil

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.

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.

7) Pull the piston rod fully upward, and install rubber seat
and spring seat.
NOTE:
Ensure that upper spring seat is positioned with“OUT”
mark facing outward.
8) Install strut mount to the piston rod, and tighten the
self-locking nut temporarily.
CAUTION:
Be sure to use a new self-locking nut.
G4M0507
9) Using hexagon wrench to prevent strut rod from turning,
tighten self-locking nut with ST.
Tightening torque:
54±5 N⋅m (5.5±0.5 kg-m, 39.8±3.6 ft-lb)
ST 927760000 STRUT MOUNT SOCKET
10) Loosen the coil spring carefully.
E: INSTALLATION
1) Install strut mount at upper side of strut to body and
tighten with nuts.
Tightening torque:
20±6 N⋅m (2.0±0.6 kg-m, 14.5±4.3 ft-lb)
2) Connect housing to lower side of strut.
3) Position aligning mark on camber adjusting bolt with
aligning mark on lower side bracket of strut.
CAUTION:

While holding head of adjusting bolt, tighten self-
locking nut.

Be sure to use new self-locking nut.
Tightening torque:
152±20 N⋅m (15.5±2.0 kg-m, 112±14 ft-lb)
4) Install A.B.S. sensor harness to strut. (A.B.S. equipped
models.)
Tightening torque:
152±20 N⋅m (15.5±2.0 kg-m, 112±14 ft-lb)
5) Install brake hose at lower side of strut with clamp.
G4M0503
6) Install union bolts which secure brake caliper to brake
hose.
Tightening torque:
18±3 N⋅m (1.8±0.3 kg-m, 13.0±2.2 ft-lb)
CAUTION:
Be sure to bleed air from brake system.
7) Install wheels.
NOTE:
Check wheel alignment and adjust if necessary.

Compressor clutch trouble is often caused by clutch slip-
page and noise. Check and take corrective measures, as
required.

2) Check that clearance between drive plate and pulley
over the entire perimeter is within specifications.
Clearance:
0.3 — 0.6 mm (0.012 — 0.024 in)
