Front Strut Assembly Removal and Installation

S6JB0A2206003

Removal

NOTE
When servicing component parts of strut
assembly, remove strut rod cap and then
loosen strut nut a little before removing strut
assembly. This will make service work easier.
Note that the nut must not be removed at this
point.

1) Hoist vehicle, allowing front suspension to hang free.
2) Remove wheel and disconnect stabilizer joint (1)

from strut bracket.
When loosening joint nut, hold stud with hexagon
wrench.

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”.

5) Remove wheel speed sensor harness clamp bolt (3)

and then detach wheel speed sensor harness (5)
from strut bracket as shown in figure.

6) Remove strut bracket bolts and nuts (4).

7) Remove strut support nuts (1).

NOTE
Hold strut by hand so that it will not fall off.

8) Remove strut assembly.

Installation
Install strut assembly by reversing removal procedure,
noting the following instructions.
• Insert bolts in such direction as shown in figure.
• Tighten all fasteners to specified torque.

Tightening torque
Strut bracket nut (a): 135 N·m (13.5 kgf-m, 98.0 lb-
ft)
Brake hose mounting bolt (c): 25 N·m (2.5 kgf-m,
18.0 lb-ft)
Stabilizer joint nut (d): 60 N·m (6.0 kgf-m, 43.5 lb-
ft)
Wheel speed sensor harness clamp bolt (e): 11
N·m (1.1 kgf-m, 8.0 lb-ft)

2B-6 Front Suspension:

• Lower hoist and vehicle in unloaded condition, tighten

strut support nuts (b) to specified torque.

Tightening torque
Strut support nut (b): 50 N·m (5.0 kgf-m, 36.5 lb-ft)

CAUTION

!

If bracket bolt and nut are reused, apply
engine oil to thread, bearing and trunk
surface.

NOTE

• Don’t twist brake hose and wheel speed

sensor harness when installing them.

• Insert strut bracket bolt from vehicle

forward.

• Tighten wheel nuts to specified torque.

Tightening torque
Wheel nut: 100 N·m (10.0 kgf-m, 72.5 lb-ft)

• After installation, confirm front wheel alignment and

adjust auto leveling headlight system (if equipped)
referring to “Initialization of Auto Leveling Headlight
System in Section 9B”.

Front Strut Assembly Disassembly and
Assembly

S6JB0A2206004

WARNING

!

Use a regular coil spring compressor and
follow the operation procedure described in
the Instruction Manual.
Otherwise, spring might come off and injure.

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

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.

Front Suspension: 2B-7

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.

NOTE
If using caulking nut, do not reuse.

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

Tightening torque
Strut nut (a): 70 N·m (7.0 kgf-m, 51.0 lb-ft)

Front Strut Assembly Check

S6JB0A2206005

• 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.
