1999 SUBARU LEGACY steering wheel

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.
ST 927380000 ADAPTER
B4M0567A
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).
G4M0482
3) Tighten tie-rod lock nut.
Tightening torque:
83
±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.

1. On-car Services

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.

a: Right rear wheel toe angle
b: Left rear wheel toe angle
B4M0194A
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.

Turn tie-rod to adjust steering angle of both inner
and outer wheels.

B: INSPECTION
1) Check bushing for cracks, fatigue or damage.
2) Check stabilizer link for deformities, cracks, or
damage, and bushing for protrusions from the hole
of stabilizer link and its play.
C: INSTALLATION
1) To install, reverse the removal procedure.
NOTE:
IInstall bushing (on front crossmember side)
while aligning it with paint mark on stabilizer.
IEnsure that bushing and stabilizer have the
same identification colors when installing.

A: REMOVAL
1) Disconnect ground cable from battery.
2) Loosen front wheel nuts.
3) Lift-up vehicle, and remove front tires and
wheels.
4) Remove both stabilizer and jack-up plate.
G4M0520
5) Disconnect tie-rod end from housing.
6) Remove front exhaust pipe.
7) Remove front transverse link from front cross-
member and body.
G4M0521
8) Remove nuts attaching engine mount cushion
rubber to crossmember.
9) Remove self-locking nuts connecting steering
U/J and pinion shaft.
10) Lift engine by approx. 10 mm (0.39 in) by
using chain block.
11) Support crossmember with a jack, remove
nuts securing crossmember to body and lower
crossmember gradually along with steering gear-
box.
CAUTION:
When removing crossmember downward, be
careful that tie-rod end does not interfere with
DOJ boot.
