REMOVAL
1) Hoist vehicle.
2) Remove stabilizer bar mount bush bracket bolts.
3) Remove stabilizer ball joint nuts, washers and bushings.
4) Remove stabilizer bar with its ball joints.
5) Disconnect stabilizer ball joints from stabilizer bar.
INSTALLATION
NOTE:
For correct installation of stabilizer bar, side-to-side, be sure
that color paint on stabilizer bar aligns with mount bush, both
right and left, as shown.
1) Connect stabilizer ball joints and stabilizer bar.
2) Install stabilizer ball joints to control arms.
NOTE:
Do not tighten stabilizer ball joint nuts completely.
3) Install stabilizer bar mount bush brackets.
4) When installing stabilizer, loosely assemble all components
while insuring that stabilizer is centered, side-to-side.
Check that ball joint is set at neutral position seeing from body
upper side.
5) Tighten stabilizer bracket bolts and stabilizer ball joint nuts to
specified torque.

WARNING:

When performing a road test, select a place where there is no traffic or possibility of a traffic accident
and be very careful during testing to avoid occurrence of an accident.

Road test should be carried out with 2 persons, a driver and a tester, on a level road.
1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTC, pending DTC and freeze frame data in PCM memory by using scan tool and check fuel level meter
indication is 1/4 or more.
3) Start engine, warm it up to normal operating temperature and shift transfer lever to ª2Hº or ª4Hº range.
4) Increase vehicle speed with D range, and check that gear position changes from 1st to 2nd and keep driving
about 20 mph, 30 km/h in 2nd of ªDº range for 10 seconds. (Throttle valve should be not at idle position and
the opening should be kept constant in this step.)
5) Keep driving about 50 mph, 80 km/h in 4th of ªDº range for 10 seconds.
6) Release accelerator pedal, decrease vehicle speed and stop vehicle.
