• 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
1
. Apply a force of 20 N
(2 kgf, 4 lb) in the opposite direction of “W”, then
read dial gauge indication: P
2
.
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.

If any cracks or damage are found, replace it with a
new one.

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

tions, cracks, etc., and replace it with a new one if
defective.
