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.

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

2) Slide boot toward the center of shaft and remove snap ring from
outer race, then take shaft out of outer race.
3) Remove circlip and then cage.
4) Remove inside and outside boots from shaft.
CAUTION:

Do not disassemble wheel side joint (outboard joint). If
any malcondition is found in joint, replace it as assem-
bly.

Do not disassemble ball joint of differential side joint.
If any malcondition is found in ball joint, replace differ-
ential side joint assembly.
INSPECTION

Check boots for breakage or deterioration. Replace them as nec-
essary.

Check circlip, snap ring and boot bands for breakage or deforma-
tion. Replace as necessary.
CLEANING

Wash disassembled parts (except boots) in degreaser. After
washing, dry parts completely by blowing air.

Clean boots with cloth. DO NOT wash boots in degreaser, such
as gasoline or kerosene, etc.
Washing in degreaser causes deterioration of boot.

ASSEMBLY
CAUTION:

To prevent any problem caused by washing solution, do
not wash joint boots. Degreasing of those parts with cloth
is allowed.

For M / T vehicle with H25 engine
To ensure full performance of joint as designed, be sure
to distinguish between two types of grease in repair set
and apply specified volume to respective joint. i.e. yellow
grease to wheel side joint and black one to differential
side.

Bend each boot band against forward rotation.

Do not squeeze or distort boot when fastening it with
bands.
Distorted boot caused by squeezing air may reduce its du-
rability.
1) Fully apply joint grease to wheel side joint.
Use joint grease in the tube included in spare part.
2) Fit wheel side boot on shaft.
Fill up inside of boot with joint grease of about 90 gram.
Before fixing boot band, insert screwdriver into boot on joint side
and allow air to enter boot so that air pressure in boot becomes
the same as atmospheric pressure.
3) Fixing boot band.
4) Install boot onto drive shaft till its small diameter side fits to shaft
groove and fix there with boot band.
5) Install cage to shaft.
CAUTION:
Install cage directing smaller outside diameter side to
shaft end.
6) Install circlip by using snap ring plier.
