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 up.
(2) Move the piston rod to the center of its
entire stroke.
(3) While holding the piston rod end with
fingertips, move the rod up and down.
(4) If the piston rod moves at least 10 mm (0.39
in) in the former step, purge air from the strut.
3) Air purging procedure
(1) Place the strut vertically with the piston rod
facing up.
(2) Fully extend the piston rod.
(3) With the piston rod fully extended, place the
piston rod side down. The strut must stand ver-
tically.
(4) Fully contract the piston rod.
(5) Repeat 3 or 4 times from the first step.
NOTE:
After completely purging air from the strut, be sure
to place the strut with the piston rod facing up. If it
is laid down, check for entry of air in the strut as
outlined under "Checking for the presence of air".
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.
(1) Flat (top side)
(2) Identification paint
(3) Inclined (bottom side)

5) Set the coil spring correctly so that its end face
(1) fits well into the spring seat as shown in the
figure.
6) Install helper and dust cover to the piston rod.
7) Pull the piston rod fully upward, and install rub-
ber seat and upper spring seat.
NOTE:
Ensure that upper spring seat is positioned as
shown in figure.

8) Install strut mount to the piston rod, and tighten
the self-locking nut temporarily.
CAUTION:
Be sure to use a new self-locking nut.
9) Using hexagon wrench to prevent strut rod from
turning, tighten self-locking nut with ST.
