SECTION 3D
FRONT SUSPENSION
CAUTION:

All front suspension fasteners are an important attaching part in that it could affect the performance
of vital parts and systems, and / or could result in major repair expense. They must be replaced with
one of the same part number or with an equivalent part if replacement becomes necessary. Do not
use a replacement part of lesser quality or substitute design. Torque values must be used as specified
during reassembly to assure proper retention of this part.

Never attempt to heat, quench or straighten any front suspension part. Replace it with a new part or
damage to the part may result.

SUSPENSION CONTROL ARM JOINT CHECK
1) Check for smoothness of rotation.
2) Inspect ball stud for damage.
3) Inspect dust cover for damage.
Replace any parts found defective in steps 1) ± 3).
SUSPENSION CONTROL ARM BUSHING
CHECK
Inspect for damage, wear or deterioration.
WHEEL DISC, NUT & BEARING CHECK
1) Inspect each wheel disc for dents, distortion and cracks.
Disc in badly damaged condition must be replaced.
2) Check wheel nuts for tightness and retighten them to specifica-
tion as necessary.
Tightening Torque
(a): 100 N
.m (10.0 kg-m, 72.5 lb-ft)
3) Check wheel bearing for wear. After retightening lock nut to spe-
cified torque, apply dial gauge to wheel hub center and measure
thrust play.
Thrust play limit: 0.05 mm (0.002 in.)
When measurement exceeds limit, replace bearing.
4) By rotating wheel actually, check wheel bearing for noise and
smooth rotation. If defective, replace bearing.

INSTALLATION
Reverse removal procedure to install coil spring.
NOTE:
Upper and lower diameters of coil spring are different.
Bring larger diameter end at bottom and set its open end in
place on spring seat.

Be sure to use specified torque for tightening each fastener.

Refer to torque specification chart at the end of this section.

As for ball stud nut, be sure to insert split pin and bend it after tight-
ening it.

Tighten tie-rod end nut with pushing ball stud to upper side so as
not ball stud to be rotated.

For 4WD vehicle
Apply lithium grease to front drive shaft washer and front wheel
spindle outer.
ªAº: Grease 99000-25010

For 4WD vehicle
When installing circlip to drive shaft, utilize screw hole in drive
shaft to pull it out and bring large diameter of circlip at right as
shown.

For 4WD vehicle
When installing axle shaft drive flange to wheel hub, apply sealant
to mating surface of axle shaft drive flange and tighten flange bolt
to specified torque.

with ABS).
CAUTION:

Pull out sensor rotor from wheel hub gradually and
evenly.

Do not reuse sensor rotor once removed.
Be sure to new sensor rotor when installing.
11) Remove hub bolts from hub.
INSTALLATION
1) Insert new stud in hub hole. Rotate stud slowly to assure serra-
tions are aligned with those made by original bolt.
