STRUT MOUNT
Check the rubber part for deformation, abnormal cracks or deterioration, and then replace it with a new part if defective.
DUST COVER
If abnormal cracks or damage are found, replace it with a new part.
COIL SPRING
If a permanent strain is found, replaced it with a new part.
HELPER
If abnormal cracks or damage are found, replace it with a new part.
DISPOSAL
| CAUTION | Before handling struts, be sure to wear goggles to protect eyes from gas, oil and cutting powder. Do not disassemble the strut damper or throw into flames. When discarding gas filled struts, drill holes in them to purge the gas. |
Scheme 67
- Place the strut on a level surface with the piston rod fully expanded.
- Using a 2 - 3 mm (0.08 - 0.12 in) dia. drill, make holes in areas shown in the figure.
IMPROPER VEHICLE POSTURE OR IMPROPER WHEEL ARCH HEIGHT
| Possible cause | Corrective action |
|---|---|
| (1) Permanent distortion or damage of the coil spring | Replace. |
| (2) Rough operation of strut or shock absorber | Replace. |
| (3) Improper installation of strut or shock absorber | Replace with appropriate parts. |
| (4) Installation of the wrong coil spring | Replace with appropriate parts. |
INSPECTION CHART
POOR RIDE COMFORT
- Large rebound shock
- Rocking of the vehicle continues too long after running over bump and hump.
- Excessive shock in bumping INSPECTION CHART Possible cause Corrective action (1) Damaged coil spring Replace. (2) Overinflation of tires Adjust. (3) Improper wheel arch height Replace the coil springs with new parts. (4) Fault in operation of strut or shock absorber Replace. (5) Damage or deformation of strut mount or shock absorber mount Replace. (6) Unsuitable length (maximum or minimum) of strut or shock absorber Replace with appropriate parts. (7) Abnormal deformation or loss of bushing Replace. (8) Deformation or damage of helper in strut assembly or shock absorber Replace. (9) Oil leakage from the strut or shock absorber Replace.
