Front Strut Assembly Disassembly and
Assembly

S5JB0A2206004

Disassembly

1) Attach special tool (A) to coil spring as shown. Turn

special tool bolts alternately until coil spring tension
is released. Rotate the strut around its axis to
confirm that the coil spring is released or not.

Special tool
(A): 09943–25010

WARNING

Use a regular coil spring compressor and
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

spring end (2) onto spring lower seat (1) as shown.

NOTE
End of coil spring must not interfere with
step of spring lower seat.

4) Pull strut rod as far up as possible and use care not

to allow it to retract into strut.

5) Attach coil spring seat to coil spring upper seat and

then install strut dust cover firmly.

6) Install coil spring upper seat with strut dust cover on

coil spring and then spring upper seat (1) aligning
“OUT” mark (3) on spring upper seat and center of
strut bracket (2).

7) Install bearing (3), strut support (2) and strut nut (1)

in this sequence.
Tighten strut nut (1) holding stud with special tools.

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

Tightening torque
Strut nut (a): 90 N·m (9.0 kgf-m, 65.0 lb-ft)

Front Strut Assembly Check

S5JB0A2206005

• Inspect strut for oil leakage, damage or deformation.

If defect is found, replace strut as an assembly unit,
because it can not be disassembled.

• Inspect strut function referring to the following

procedures:

1) Check and adjust tire pressures as specified.
2) Bounce vehicle body up and down 3 or 4 times

continuously by pushing front end of the vehicle side
body to check strut.
Also, note how many times vehicle body rebounds to
stop after force application.

3) Repeat the same procedure to the other strut to

confirm that the both side struts equally respond.

If conditions of struts are in doubt, compare them with
known-good vehicle or strut.
• Inspect bearing for wear, abnormal noise or gripping.

If defective, replace.

• Inspect coil spring seat for cracks or deformation.

If defective, replace.

• Inspect bump stopper for deterioration.

If defective, replace.

• Inspect rebound stopper and strut mount for wear,

cracks or deformation.
If defective, replace.
