Front Strut Assembly Check

S5JB0E2206005

• 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.
