(4) If the starting torque exceeds the upper limit of standard value, replace the lower arm assembly.Even if the starting torque is below the lower limit of the
standard value, the ball joint may be reused unless it has
drag and excessive play.

2. REMOVAL OF FRONT EXHAUST PIPE
After disconnection of the front exhaust pipe assembly and
the exhaust manifold, use wire, etc. to hang the front
exhaust pipe down.
Caution Do not bend the flexible joint more than shown in the
figure, because there is danger the inside may be
damaged if it is bent too much.
7. REMOVAL OF STABILIZER LINK MOUNTING NUTS Using a wrench or similar tool to secure the ball studs at
both ends of the stabilizer link, remove the mounting nuts.
12. REMOVAL OF STABILIZER
BAR
(1) Disconnect either the left or right lower arm from the crossmember, and slightly lower the installation part.
(2) Pull out both ends of the stabilizer bar to the rear of the drive shaft.
NOTE
First pass the end of the stabilizer bar (at the side at
which the lower arm was not lowered) under the drive shaft, and then pull out toward the rear.

(3) Move either the left or right stabilizer bar until the endof the stabilizer bar clears the lower arm.
(4) With the end that has cleared the lower arm, pull out the stabilizer bar diagonally.
INSPECTION M33lCAH
l Check the bushing for wear and deterioraton.
l Check the stabilizer bar for deterioration or damage.
l Check the stabilizer link bail joint dust cover for cracks.
l Check all bolts for condition and straightness.

10. INSTALLATION OF STABILIZER BAR BRACKET
(1) Provisionally tighten the stabilizer bar bracket.
(2) Align the bushing end with the marked part of the stabilizer bar, and then fully tighten the stabilizer bar
bracket.
(3) Provisionally tighten the removed lower arm installation part to the crossmember.
Caution
Make the final tightening with the vehicle in the
unladen condition; the tightening should be at the
specified tightening torque.
7. INSTALLATION OF STABILIZER LINK MOUNTING NUTS
Using a wrench or similar tool to secure the ball studs at
both ends of the stabilizer link, tighten the mounting nuts.

AGE
For information concerning checking for air leakage of the
shock absorber assembly, refer to the section concerning the
strut assembly

1. CONNECTION OF AIR TUBE (1) After applying a coating of rubber grease to the O-ring, install the O-ring, bush and joint at the shock absorber
assembly side.
Caution
1.The O-ring might be damaged if it is installed at
the air tube side and then the insertion is made.
2. The bush must be installed so that the projec-
tion part is facing in the direction indicated in
the illustration.
(2) First insert the air tube until resistance is felt, and then push in the tube until the painted place on the air tube.
Caution
Air leakage may occur if the air tube connection is
not complete and secure.
(3) In order to prevent double-folding of the air spring diaphragm after reconnection of the air tube. the
vehicle-height switch should be pressed (wrth the
vehicle lifted) two seconds or more so as to
Supply air
to the air spring.
NOTE
By using the switch as described above, air should be
introduced to the rear air springs and front air springs, in
that sequence, for five seconds each.
