1996 SUBARU LEGACY spare wheel

1. WHEEL ARCH HEIGHT
1) Adjust tire pressure to specifications.
2) Set vehicle under“curb weight”conditions. (Empty lug-
gage compartment, install spare tire, jack, service tools,
and top up fuel tank.)
3) Set steering wheel in a wheel-forward position.
4) Suspend thread from wheel arch (point“A”in figure
below) to determine a point directly above center of
spindle.
5) Measure distance between measuring point and center
of spindle.

2. OIL LEAK CHECK PROCEDURE AND
REPLACEMENT PARTS
NOTE:
Parts requiring replacement are described in the smallest
unit of spare parts including damaged parts and spare
parts damaged. In actual disassembly work, accidental
damage as well as inevitable damage to some related
parts must be taken into account, and spare parts for them
must also be prepared. However, it is essential to pinpoint
the cause of trouble, and limit the number of replacement
parts as much as possible.
1) Leakage from“a”
The oil seal is damaged. Replace valve assembly with a
new one.
2) Leakage from“b”
The torsion bar O-ring is damaged. Replace valve assem-
bly with a new one.
3) Leakage from“c”
The oil seal is damaged. Replace valve assembly with a
new one.
4) Leakage from“d”
The pipe is damaged. Replace the faulty pipe or O-ring.
5) If leak is other than a, b, c, or d, and if oil is leaking from
the gearbox, move the right and left boots toward tie-rod
end side, respectively, with the gearbox mounted to the
vehicle, and remove oil from the surrounding portions.
Then, turn the steering wheel from lock to lock 30 to 40
times with the engine running, then make comparison of
the leaked portion immediately after and several hours
after this operation.
6) Leakage from“e”
The cylinder seal is damaged. Replace rack bush with a
new one.
7) Leakage from“f”
There are two possible causes. Take following step first.
Remove the pipe assembly B from the valve housing, and
close the circuit with ST.
ST 926420000 PLUG
Turn the steering wheel from lock to lock 30 to 40 times
with the engine running, then make comparison of the
leaked portion between immediately after and several
hours after this operation.
CAUTION:

If leakage from“f”is noted again:
The oil seal of pinion and valve assembly is damaged.
Replace pinion and valve assembly with a new one. Or
replace the oil seal and the parts that are damaged
during disassembly with new ones.

If oil stops leaking from“f”:
The oil seal of rack housing is damaged.
Replace the oil seal and the parts that are damaged
during disassembly with new ones.

3. CHECKING THE HYDRAULIC UNIT WITH BRAKE
TESTER
1) In the case of AWD vehicles, install a spare fuse with
the FWD connector in the engine compartment to simulate
FWD vehicles.
B4M0082A
2) Connect diagnosis terminals to 3 terminals (K) and 6
terminals (L) of the diagnosis connector beside driver seat
heater unit.
G4M0464
3) Set the front wheels or rear wheels on the brake tester
and set the select lever’s position at“neutral”.
4) Operate the brake tester.
5) Perform sequence control.
(1) Turn ignition switch ON.
(2) The ABS warning light comes on.
(3) Depress the brake pedal within 0.5 seconds after
the warning light goes out so that the brake tester reg-
isters a pressure equal to the initial value.
CAUTION:
Do not depress the clutch pedal.
NOTE:
The engine must not be operating.
6) Hydraulic unit begins to work; and check the following
working sequence.
(1) The left front wheel performs decompression,
holding, and compression in sequence, and subse-
quently the right front wheel repeats the cycle.
(2) Simultaneously both right and left rear wheel per-
form decompression, holding, and compression in
sequence.

7) Read values indicated on the brake tester and check if
the fluctuation of values, when decompressed and
compressed, meet the standard values.
Initial value When decompressed When compressed
Front wheel 1,961 N (200 kg, 441 lb) 245 N (25 kg, 55 lb) 1,961 N (200 kg, 441 lb)
Rear wheel 686 N (70 kg, 154 lb) 245 N (25 kg, 55 lb) 686 N (70 kg, 154 lb)

In case of hydraulic unit plunger piston malfunction:
Initial value When decompressed When compressed
Rear right wheel 686 N (70 kg, 154 lb) 245 N (25 kg, 55 lb) 686 N (70 kg, 154 lb)
Rear left wheel 686 N (70 kg, 154 lb) 686 N (70 kg, 154 lb) 686 N (70 kg, 154 lb)
8) After checking, also check if any irregular brake pedal
tightness is felt.
9) In case of AWD vehicles, remove the spare fuse from
the FWD connector in the engine compartment to return to
the original AWD state.
C: SEQUENCE CONTROL
Under the sequence control, after the hydraulic unit sole-
noid valve is driven, the operation of the hydraulic unit can
be checked by means of the brake tester or pressure
gauge.
B4M0082A
1. OPERATIONAL GUIDELINES OF THE SEQUENCE
CONTROL
1) Connect diagnosis terminals to 3 terminals (K) and 6
terminals (L) of the diagnosis connector beside driver seat
heater unit.
2) Set the speed of all wheels at 4 km/h (2 MPH) or less.
3) Within 0.5 seconds after the ABS warning lamp goes
out, immediately after the ignition switch is turned to on,
depress the brake pedal and hold.
CAUTION:
Do not depress the clutch pedal.
NOTE:

When the ignition switch is set to on, the brake pedal
must not be depressed.

Engine must not operate.
