attachment (SST) and sliding hammer (SST) to remove wheel
hub and bearing assembly from axle housing.
CAUTION:
When placing onto bench vise, be careful not to damage
strut mounting surface of steering knuckle. Use an alumi-
num plate or another suitable tool.
2. Use a bearing replacer (suitable tool), puller (suitable tool), and
drift (SST) to remove inner race of outer-wheel bearing from
wheel hub.
3. Remove back plate installation bolt and anchor block. Remove

7. Install boot securely into grooves (indicated by * marks) shown
in the figure.
CAUTION:
If there is grease on boot mounting surfaces (indicated by *
marks) of joint, boot may come off. Remove all grease from
surfaces.
8. Check that boot installation length “L” is the length indicated
below. Insert a flat-bladed screwdriver or similar tool into smaller
side of boot. Remove air from boot to prevent boot deformation.
CAUTION:

Boot may break if boot installation length is less than
standard value.

Be careful that screwdriver tip does not contact inside
surface of boot.
9. Secure big and small ends of boot with new boot bands as
shown in figure.
CAUTION:
Rotate housing and check that boot installation position
does not change. If position changes, reinstall boot bands.
Wheel Side
1. Use a drift (SST) to press-fit sensor rotor into joint sub-assem-
bly.
CAUTION:
Discard the old sensor rotor; replace with a new one.

REMOVAL
1. Remove tyre. Remove brake caliper and hung it aside.
CAUTION:
Avoid depressing brake pedal with brake caliper removed.
2. Remove electrical wires of wheel sensor from strut.
3. Remove brake hose lock plate.
4. Remove mounting bolts and nuts securing steering knuckle to strut.
5. Remove mounting nuts on upper mounting plate and remove upper mounting plate and strut from vehicle.
INSTALLATION

Refer to FSU-5, "Components" in “Front Suspension Assembly” for tightening torque. Tighten in the
reverse order of removal.

Be sure arrows on strut mount insulator and spring upper seat
are positioned as shown. Also be sure notch in strut spacer is
positioned as shown. Then install strut.

Assemble upper mounting plate with its notch facing toward the
outside.
Disassembly and AssemblyEES00075
DISASSEMBLY
1. Install strut attachment (SST) to strut and fix it in a vise.
CAUTION:
When installing strut attachment (SST), wrap a shop cloth
around strut to protect it from damage.
2. Slightly loosen piston rod lock nut.
WARNING:
Do not remove piston rod lock nut completely. If it is
removed completely, coil spring jumps out and may cause
serious damage or injury.
3. Compress coil spring using a spring compressor.
WARNING:
Make sure that the pawls of the two spring compressors are firmly hooked on the spring. The
spring compressors must be tightened alternately so as not to tilt the spring.
4. After making sure coil spring is free between upper and lower seats after Step 3. Remove piston rod lock
nut.
5. Remove small parts on strut.

Remove strut spacer, strut mount insulator, strut mounting insulator bracket thrust bearing, spring upper
seat, and upper rubber seat. Then remove coil spring.
6. Remove bound bumper from spring upper seat.
7. Gradually release spring compressor (commercial service tool), and remove coil spring.
INSPECTION AFTER DISASSEMBLY
Strut

Check strut for deformation, cracks, and damage, and replace if necessary.

Check piston rod for damage, uneven wear, and distortion, and replace if necessary.

Check welded and sealed areas for oil leakage, and replace if necessary.
