C: INSPECTION
Check the disassembled parts for cracks, damage and
wear, and replace with new parts if defective.
G4M0508
1. DAMPER STRUT
1) Check for oil leakage.
2) Move the piston rod up and down to check its 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 the rod: L [10 mm (0.39 in)], then apply a force
of W [20 N (2 kg, 4 lb)] to threaded portion. With the force
of 20 N (2 kg, 4 lb) applied, read dial gauge indication: P
1.
Apply a force of 20 N (2 kg, 4 lb) in the opposite direction
of“W”, then read dial gauge indication: P
2. The free play
is determined by the following equation:
Play = P
1,P2
Limit of play:
Less than 0.8 mm (0.031 in)
If the play is greater, replace the strut with new one.
2. STRUT MOUNT
Check rubber part for wear, cracks and deterioration, and
replace it with new one if defective.
3. DUST COVER
If any cracks or damage are found, replace it with new one.
4. COIL SPRING
When vehicle posture is uneven, although there are no
considerable reasons like tire puncture, uneven loading,
etc., check coil spring and spring seats for cracks,
deformation, etc., and replace it with a new one if defective.
5. HELPER
Replace it with new one if cracked or damaged.

D: ASSEMBLY
1) Before installing coil spring, strut mount, etc., on the
strut, check for the presence of air in the dampening force
generating mechanism of the strut since air prevents
proper dampening force from being produced.
2) Checking for the presence of air
(1) Place the strut vertically with the piston rod facing
upward.
(2) Move the piston rod to the center of its entire
stroke.
(3) While holding the piston rod end with finger-tips,
move the rod up and down.
(4) If the piston rod moves at least 10 mm (0.39 in) in
step (3), purge air from the strut.
3) Air purging procedure
(1) Place the strut vertically with the piston rod facing
upward.
(2) Fully extend the piston rod.
(3) With the piston rod fully extended, place the piston
rod side down. The strut must stand vertically.
(4) Fully contract the piston rod.
(5) Repeat 3 or 4 times steps (1) through (4) above.
NOTE:
After completely purging air from the strut, be sure to place
the strut with the piston rod facing upward. If it is laid down,
check for entry of air in the strut as outlined under item 2)
above.
B4M0568A
4) Using a coil spring compressor, compress the coil
spring.
NOTE:
Make sure that the vertical installing direction of coil spring
is as shown in figure.
G4M0510
5) Set the coil spring correctly so that its end face fits well
into the spring seat as shown.
6) Install helper and dust cover to the piston rod.
