6) Tighten the adjusting screw to 3.9 N·m (0.40 kgf-
m, 2.9 ft-lb) and then loosen 20°.
7) Install the lock nut. While holding the adjusting
screw with wrench, tighten the lock nut using ST.

Tightening torque (lock nut):
25 N·m (2.5 kgf-m, 18.1 ft-lb)
Hold the adjusting screw with wrench to prevent it
from turning while tightening the lock nut.
4. TIE-ROD
1) Check the tie-rod and tie-rod ends for bends,
scratches or other damage.
2) Check the connections of knuckle ball joints for
play, inspect for damage on dust seals, and check
free play of ball studs. If the castle nut is loose, re-
tighten it to the specified torque, then tighten it fur-
ther up to 60°until the cotter pin hole is aligned.
Tightening torque:
27 N·m (2.75 kgf-m, 19.9 ft-lb)
3) Check the lock nut on the tie-rod for tightness. If
it is loose, retighten it to the specified torque.
Tightening torque:
85 N·m (8.7 kgf-m, 63 ft-lb)
5. POWER STEERING FLUID LEVEL
NOTE:
•At power steering fluid temperature 20°C (68°F);
read the fluid level on the “COLD” side.
•At power steering fluid temperature 80°C
(176°F); read the fluid level on the “HOT” side.
1) Place the vehicle with engine “OFF” on a level
surface.
2) Check the fluid level using the scale on the out-
side of the reservoir tank. If the level is below MIN,
add fluid to bring it up to MAX.
NOTE:
If fluid level is at MAX level or above, drain fluid to
keep the level in the specified range of indicator by
using a syringe or the like.
Recommended fluid:
Refer to “RM” section.

6. POWER STEERING FLUID FOR LEAKS
Inspect the underside of oil pump and gearbox of
power steering system, hoses, pipes and their cou-
plings for fluid leaks.
If the fluid leaks are found, retighten their fitting
bolts (or nuts) and/or replace their parts.
NOTE:
•Wipe the leaked fluid off after correcting fluid
leaks.
•Also pay attention to clearances between hoses
(or pipes) and other parts when inspecting fluid
leaks.

A: INSPECTION
NOTE:
The level of ATF varies with fluid temperature. Pay
attention to the ATF temperature when checking
ATF level.
1) Raise the ATF temperature by driving a distance
of 5 to 10 km (3 to 6 miles). Otherwise, idle the en-
gine to raise ATF temperature to 70 — 80°C (158
— 176°F) on Subaru Select Monitor.
TION, Subaru Select Monitor.>
2) Park the vehicle on a level surface.
3) After selecting all positions (P, R, N, D), set the
select lever in “P” range. Idle the engine for 1 or 2
minutes, and measure the ATF level.
4) Make sure that the ATF level is between upper
and lower marks of the HOT side.
5) If the ATF level is below the lower mark, add rec-
ommended ATF until the fluid level is between up-
per and lower marks.
CAUTION:
•Be careful not to exceed the upper level.
•When the transmission is cold, be careful not
to add ATF to the upper level on HOT side.
Overfilling of ATF may cause oil splashing.
6) Raise the ATF temperature by driving a distance
of 5 to 10 km (3 to 6 miles). Otherwise, idle the en-
gine to raise ATF temperature to 70 — 80°C (158
— 176°F) on Subaru Select Monitor.
TION, Subaru Select Monitor.>
7) Check the ATF for leaks.
Visually check for leaks in the transmission. If there
are leaks, replace the gasket, oil seal, plug or other
parts.
B: REPLACEMENT
1) Lift-up the vehicle.
2) Remove the ATF drain plug to drain ATF.
CAUTION:
Directly after the vehicle has been running or
the engine has been long idle running, the ATF
is hot. Be careful not to burn yourself.
3) Check the condition of ATF.
4) Tighten the ATF drain plug.
NOTE:
Use a new gasket.
Tightening torque:
20 N·m (2.0 kgf-m, 14.8 ft-lb)
5) Lower the vehicle.

A: INSPECTION
1) Park the vehicle on a level surface.
2) Remove the collector cover.
3) Remove the oil level gauge and wipe it clean.
4) Reinsert the level gauge all the way. Make sure
the level gauge is inserted correctly and in the
proper orientation.
5) Remove the oil level gauge again, and check the
level of differential gear oil. If the differential gear oil
level is below “L” line, add oil to bring the level up to
“F” line.
NOTE:
To prevent overfilling the differential gear oil, do not
add oil above the “F” line.
B: REPLACEMENT
1) Lift-up the vehicle.
2) Remove the differential gear oil drain plug using
TORX® BIT T70, and then drain differential gear
oil.
CAUTION:
•Immediately after the vehicle has been run-
ning or after idling for a long time, the differen-
tial gear oil will be hot. Be careful not to burn
yourself.
•Be careful not to spill differential gear oil on
the exhaust pipe to prevent it from emitting
smoke or causing a fire. If differential gear oil is
spilled on the exhaust pipe, wipe it off com-
pletely.
3) Tighten the differential gear oil drain plug using
TORX® BIT T70.
NOTE:
Use a new gasket.
Tightening torque:
70 N·m (7.1 kgf-m, 51.6 ft-lb)
