Front Strut Assembly Removal and Installation

S5JB0E2206003

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 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 
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.

2B-6 Front Suspension: 

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)
Front wheel speed sensor harness clamp bolt 
(e):  10 N·m (1.0 kgf-m, 7.5 lb-ft)

• 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 reuse strut bracket bolt and nut, apply 
engine oil to thread, bearing and trunk 
surface.

 

NOTE

• Don’t twist brake hose and ABS wheel 

speed sensor harness (if equipped) 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 headlight auto leveling system referring to

Assembly

S5JB0E2206004

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
