S5JB0E2206003

Removal

NOTE
When servicing component parts of strut
assembly, remove strut rod cap and then

3) Remove brake hose mounting bolt (1) and remove

brake hose (2) from bracket.

4) Disconnect front height sensor (if equipped) from

suspension control arm for left side referring to
“Height Sensor Removal and Installation (If
Equipped) in Section 9B in related manual”.

5) Remove front wheel speed sensor harness clamp

bolt (3) (if equipped) and then detach front speed
sensor harness (5) from strut bracket as shown in

is released. Rotate the strut around its axis to
confirm that the coil spring is released or not.

Special tool
(A): 09943–25010

WARNING

follow the operation procedure described in
the Instruction Manual.

2) While keeping coil spring compressed, remove strut

nut with special tools as shown.

Special tool
(A): 09900–00411
(B): 09900–00414
(C): 09941–56510

3) Disassemble strut assembly.

Assembly
For assembly, reverse disassembly procedure, noting
the following instructions.

1) Compress coil spring with special tool (A) until total

length becomes about 310 mm (12.2 in.) as shown.

Length
“a”: 310 mm (12.2 in.)

2) Install bump stopper onto strut rod. For installing

direction, refer to the figure in “Front Strut Assembly
Components”.

3) Install compressed coil spring to strut, and place coil
