1999 SUBARU LEGACY steering wheel adjustment

B: INSPECTION AND ADJUSTMENT
1. WHEEL ARCH HEIGHT (FRONT AND
REAR)
1) Adjust tire pressure to specifications.
2) Set vehicle under ªcurb weightº conditions.
(Empty luggage 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 ªAº in
figure below) to determine a point directly above
center of spindle.
5) Measure distance between measuring point
and center of spindle.

3. CASTER (FRONT)
IInspection
1) Place front wheel on turning radius gauge.
Make sure ground contacting surfaces of front and
rear wheels are set at the same height.
2) Set ST into the center of the wheel, and then
install the wheel alignment gauge.

NOTE:
Refer to the ªSPECIFICATIONS AND SERVICE
DATAº for the caster value.
4. FRONT WHEEL TOE-IN
IInspection
1) Using a toe gauge, measure front wheel toe-in.
Toe-in:
0
±3mm(±0.12 in)
2) Mark rear sides of left and right tires at height
corresponding to center of spindles and measure
distance ªBº between marks.
3) Move vehicle forward so that marks line up with
front sides at height corresponding to center of
spindles.
4) Measure distance ªAº between left and right
marks. Toe-in can then be obtained by the follow-
ing equation:
B þ A = Toe-in
H4M1279
IAdjustment
1) Loosen the left and right side steering tie-rods
lock nuts.
2) Turn the left and right tie rods equal amounts
until the toe-in is at the specification.
Both the left and right tie-rods are right-hand
threaded. To increase toe-in, turn both tie-rods
clockwise equal amounts (as viewed from the
inside of the vehicle).

3) Tighten tie-rod lock nut.

±5 N´m (8.5±0.5 kg-m, 61.5±3.6 ft-lb)
CAUTION:
Correct tie-rod boot, if it is twisted.
NOTE:
Check the left and right wheel steering angle is
within specifications.

NOTE:
Thrust angle refers to a mean value of left and right
rear wheel toe angles in relation to vehicle body
center line. Vehicle is driven straight in the thrust
angle direction while swinging in the oblique direc-
tion depending on the degree of the mean thrust
angle.

b: Left rear wheel toe angle

NOTE:
Here, use only positive toe-in values from each
wheel to substitute foraandbin the equation.
7. STEERING ANGLE
IInspection
1) Place vehicle on a turning radius gauge.
2) While depressing brake pedal, turn steering
wheel fully to the left and right. With steering wheel
held at each fully turned position, measure both the
inner and outer wheel steering angle.

rotated fully from lock to lock without binding.
9) Check for service limit as per article of ªService
limitº.
Make replacement and
adjustment if necessary.
10) Install boot and mounting rubber to housing.
NOTE:
Apply grease through small hole in boot.11) Fit clip (large) to boot, and then install boot to
gearbox while holding boot flange.
After installing boot, fold back boot flange to the
extent that large clip can not be seen.

NOTE:
IBefore installing boot, be sure to apply grease to
the groove of tie-rod.
IInstall fitting portions of boots to the following
portions in both sides of assembled steering gear-
box.
(1) The groove on gearbox
(2) The groove on the rod
IMake sure that boot is installed without unusual
inflation or deflation.
12) Turn boot until it seats well on gearbox and
rubber mounting, then bend boot flange back.
