erates 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 the 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
force of 20 N (2 kgf, 4 lb) in the opposite direction
of "W", then read dial gauge indication: P
W
L
The free play is determined by the following equa-
tion:
Play = P , P

Limit of play:
Less than 0.8 mm (0.031 in)
If the play is greater, replace the strut.
2. STRUT MOUNT
Check rubber part for creep, cracks and deteriora-
tion, and replace it with new one if defective.
3. DUST COVER
If any cracks or damage are found, replace it with a
new one.
