2. MEASUREMENT OF STEERING EFFORT
Step Check Yes No
1CHECK STEERING EFFORT.
1) Stop the vehicle on paved road.
2) Start the engine.
3) Run the engine at idle.
4) Install a spring scale on the steering wheel.
5) Pull the spring scale at a right angle to the
steering wheel, and measure both right and left
steering wheel efforts.
NOTE:When turning the steering more quickly than
necessary from a direction to the other direction
at an engine speed over 2,000 rpm, steering ef-
fort may be heavy. This is caused by flow char-
acteristic of the fluid in the oil pump and is not a
defect.
Is the steering effort less than
29.4 N (3.0 kgf, 6.6 lb)?
Go to step 2.Adjust the back-
lash.
2CHECK STEERING EFFORT.
1) Stop the engine.
2) Pull the spring scale at a right angle to the
steering wheel, and measure both right and left
steering wheel efforts.
Is the steering effort less than
294.2 N (30 kgf, 66.2 lb)?
Go to step 3.Perform the
adjustment.
3CHECK STEERING WHEEL EFFORT.
1) Remove the universal joint.
2) Measure the steering wheel effort.
Is steering effort less than 2.26
N (0.23 kgf, 0.51 lb)?
Go to step 4.Check, adjust and
replace if neces-
sary.
4CHECK STEERING WHEEL EFFORT.
Measure the steering wheel effort.
Is the difference of steering
effort between right and left
less than 20%?
Go to step 5.Check, adjust and
replace if neces-
sary.
5CHECK UNIVERSAL JOINT.
Measure the swing torque of the joint (yoke of
steering column side).
Is the swing torque of the uni-
versal joint less than 7.3 N
(0.74 kgf, 1.64 lb)?
Go to step 6.Replace with a
new part.
6CHECK UNIVERSAL JOINT.
Measure the swing torque of the joint (yoke of
gearbox side).
Is the swing torque of the uni-
versal joint less than 3.8 N
(0.39 kgf, 0.86 lb)?
Go to step 7.Replace with a
new part.
7CHECK FRONT WHEEL.
Check the front wheels.
Does the front wheels have
unsteady revolution or rattling,
or does the brake drag?
Inspect, readjust
and replace if nec-
essary.
Go to step 8.
8CHECK TIE–ROD ENDS.
Remove the tie–rod ends.
If the tie-rod ends of suspen-
sion have unsteady revolution
or rattling?
Inspect and
replace if neces-
sary.
Go to step 9.
9BALL JOINT CHECK.
Remove the ball joint.
If the ball joints of suspension
have unsteady revolution or
rattling?
Inspect and
replace if neces-
sary.
Go to step 10.
10 CHECK GEARBOX.
Measure the rotating of gearbox.
box.>
Is the rotating resistance of
steering gearbox less than
10.5 N (1.1 kgf, 2.4 lb)? Is the
difference between right and
left sides less than 20%?
Go to step 11.Readjust the back-
lash, and if ineffec-
tive, replace the
faulty par ts.
11 CHECK GEARBOX.
Measure the sliding of gearbox.
Is the sliding resistance of
steering gearbox less than 400
N (41 kgf, 90 lb)? Is the differ-
ence between the right and left
sliding resistance less than
20%?
Steering effort is
normal.
Readjust the back-
lash, and if ineffec-
tive, replace the
faulty par ts.

nector when removing or installing.
NOTE:
To check harness for broken wires or short circuits, shake trouble spot or connector.
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Check with the user regarding when the
warning light lit or started blinking.
2) Before performing diagnostics, check the
components which might mal-affect tire pres-
sure monitor system.
Is the component that might
affect the tire pressure monitor
system normal?
Go to step 2.Repair or replace
each component.
2CHECK DIAGNOSTIC TROUBLE CODE
(DTC).
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor to data
link connector.
