REMOVAL
1. Remove cotter pin. Use a hub lock nut wrench to remove lock
nuts and washers.
2. Remove ABS wheel speed sensor from steering knuckle.
3. Use a pitman arm puller to remove tie rod from steering knuckle.
4. Remove lock plate from strut. Disconnect brake hose from strut.
5. Remove steering knuckle and strut installation bolt.
CAUTION:
Do not apply an excessive angle (22°or more) to drive shaft
joint. Firmly support steering knuckle so that slide joint is
not excessively extended.
6. Use a puller to remove drive shaft from steering knuckle.
7. As shown in the figure, use a wheel wrench or other tool to
remove drive shaft from transaxle.
CAUTION:
lWhen removing drive shaft from vehicle, be careful to
avoid interfering with brake hose, ABS wheel speed sen-
sor harness, and other parts.
lWhen removing drive shaft, do not apply an excessive
angle (22°or more) to drive shaft joint. Also be careful

WAR NIN G:
Be sure to read “General Precautions” when working on fuel system. Refer toFL-3, "
General Precau-
tions"
1. Release fuel pressure from fuel line.
Refer toEC-34, "
FUEL PRESSURE RELEASE"(WITH EURO-
OBD),EC-399, "
FUEL PRESSURE RELEASE"(WITHOUT
EURO-OBD).
2. Open fuel filer lid.
3. Open the filler cap and release the pressure inside the fuel tank.
4. Check fuel level on level place. If gauge indicates more than the
level shown in figure (full or almost full), drain fuel from fuel tank
until gauge indicates level shown in figure or below.
In case of fuel pump does not operate, take following procedure.
a. Insert fuel tube of less than 25 mm (0.98 in) in diameter into fuel
filler tube through fuel filler opening to draw fuel from fuel filler
tube.
b. Disconnect fuel filler hose from fuel filler tube.
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel
from fuel tank.
lAs a guide, fuel level becomes the position shown in figure or
below when approximately 15 liter (13-1/4 lmp qt) of fuel are drained from fuel position.
