PERIODIC MAINTENANCE SERVICES
12.Front & Rear Differential Oil
A: REPLACEMENT
1. FRONT DIFFERENTIAL
1) Drain the differential gear oil by removing drain
plug using TORX® BIT T70.
NOTE:
•Before starting work, cool off the differential gear
oil well.
•If front differential gear oil adheres to the exhaust
pipe, wipe it off completely.
2) Replace the gasket with new one, and then tight-
en the drain plug to specified torque.
Tightening torque:
70 N·m (7.1 kgf-m, 51.6 ft-lb)
3) Fill differential gear oil through the oil level
gauge hole up to the upper point of level gauge.
Recommended gear oil:
Refer to “RM” section. CANTS, RECOMMENDED MATERIALS, Rec-
ommended Materials.>
NOTE:
Each oil manufacturer has its base oil and addi-
tives. Thus, do not mix two or more brands.
Gear oil capacity:
1.3 — 1.5 2 (1 . 4 — 1 .6 U S q t , 1 . 1 — 1 .3 lmp q t)
2. REAR DIFFERENTIAL
1) Drain the oil by removing drain plug.
2) Remove the filler plug for quick draining oil.
3) Tighten the drain plug after draining oil and re-
placing with a new gasket.
Tightening torque:
29 N·m (3.1 kgf-m, 21.4 ft-lb)
4) Pour oil to the bottom end of filler plug hole.
Recommended gear oil:
Refer to “RM” section. CANTS, RECOMMENDED MATERIALS, Rec-
ommended Materials.>
Oil capacity:

Stall Test
AUTOMATIC TRANSMISSION
5. Stall Test
A: INSPECTION
NOTE:
The stall test is extremely important in diagnosing
the condition of an automatic transmission and en-
gine. It should be conducted to measure the engine
stall speeds in “R” and “2nd of manual mode”.
Purposes of the stall test:
•Operational check of the automatic transmission
clutch
•Operational check of the torque converter clutch
•Engine performance check
1) Check that the throttle valve fully opens.
2) Check that the engine oil level is correct.
3) Check that the coolant level is correct.
4) Check that the ATF level is correct.
5) Check that the differential gear oil level is cor-
rect.
6) Raise the ATF temperature to 70 to 80°C (158 to
176°F) by driving a distance of 5 to 10 km (3 to 6
miles). Confirm the ATF temperature on Subaru
Select Monitor. RENT DATA, OPERATION, Subaru Select Moni-
tor.>
7) Place the wheel chocks at the front and rear of
all wheels and apply the parking brake.
8) Move the select lever to ensure it operates prop-
erly, and then set to the “2nd gear of manual
mode”.
9) While stepping hard on the brake pedal, gradu-
ally step on the accelerator pedal.
10) When the engine speed is stabilized, quickly
record the engine speed and release accelerator
pedal.
11) Shift the select lever to “N” range, and cool
down the engine by idling it for more than one
minute.
12) Perform the procedure for “R” range in the
same way as “2nd on manual mode”.
NOTE:
•Do not continue the stall test for MORE THAN
FIVE SECONDS at a time (from fully closed throttle
to fully open throttle until stall speed reading). Do-
ing so will make the engine oil and ATF deteriorate
and the clutch and brake to be adversely affected.
•After performing the stall test, be sure to cool
down the engine for at least one minute with the se-
lect lever set in “P” or “N” range, and at an idle
speed of 1,200 rpm or less.
•If the stall speed is higher than the specified
range, attempt to finish the stall test in as short a
time as possible, in order to prevent the automatic
transmission from sustaining damage.
Stall speed (at sea level):
2,300 — 2,800 rpm
