1. DAMPER STRUT
1. Check for oil leakage.
2. Move the piston rod up and down to check that it operates smoothly without any binding.
3. Play of piston rod
^
Measure the play as follows:
Fix the outer shell and fully extend the rod. Set a dial gauge at the end of the rod: L [10 mm (0.39 inch)], then apply a force of W [20 N (2 kgf,
4 lb.)] to threaded portion. With the force of 20 N (2 kgf, 4 lb.) applied, read the dial gauge indication: P1. Apply a force of 20 N (2 kgf, 4 lb.)
in the opposite direction of "W", then read the dial gauge indication: P2.
The free play is determined by the following equation:
Play = P1, P2
Limit of play: Less than 0.8 mm (0.031 inch)
If the play is greater, replace the strut.
2. STRUT MOUNT
Check the rubber part for creep, cracks and deterioration, and replace it with a new one if defective.
3. DUST COVER
If any cracks or damage are found, replace it with a new one.
4. COIL SPRING
One having permanent strain should be replaced with a new one. When the vehicle posture is uneven, although there are no considerable reasons like
tire puncture, uneven loading, etc., check the coil spring for its free length referring to specifications, cracks, etc., and replace it with a new one if
defective.
5. HELPER
Replace it with a new one if cracked or damaged.
