and wear, and replace with new parts if defective.
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 outer shell and fully extend the rod. Set a dial
gauge at the end of rod: L [10 mm (0.39 in)], 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 dial gauge indication: P
(2 kgf, 4 lb) in the opposite direction of "W", then
read dial gauge indication: P
W
L
Limit of play (P
0.8 mm (0.031 in)
If the play is greater than limit, replace the strut.
2. STRUT MOUNT
Check the rubber part for creep, cracks and deteri-
oration, 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 un-
even, although there are no considerable reasons
like tire puncture, uneven loading, etc., check the
coil spring for its free length referring to specifica-
tions, cracks, etc., and replace it with a new one if
