Front Strut Assembly Inspection

WARNING: When handling front strut assembly (1) in which low-pressure gas and oil are sealed, make sure to observe the following precautions.

Do not disassemble the assembly.
Do not put the assembly into the fire.
Do not store the assembly where it gets hot.
Before disposing of the assembly, be sure to drill a hole (approximately 3 mm (0.1 in.) in diameter) (2) in it at location shown in figure to let low-pressure gas and oil out. Be sure to wear eye shield since low-pressure gas discharged may be accompanied by drill swarf although the gas is harmless.

Inspect strut for oil leakage, damage or deformation.
If defect is found, replace strut as an assembly unit, because it cannot be disassembled.

Inspect front strut assembly function using the following procedure:
1. Check and adjust tire pressures to specification.
2. Bounce vehicle body up and down 3 or 4 times, continuously by pushing front end of vehicle's side body on one side to check strut assembly.
  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 spring upper seat for cracks or deformation. If defective, replace spring upper seat.
Inspect strut bearing and bump stopper for wear, cracks or deformation. If defective, replace front strut bearing and bump stopper.
