Assembly

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.





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.





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.





7) Pull the piston rod fully upward, and install rubber seat and spring seat.

NOTE: Ensure that upper spring seat is positioned with "OUT" mark facing outward.

8) Install strut mount to the piston rod, and tighten the sell-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.

Tightening torque:
54 ± 5 Nm (5.5 ± 0.5 kg-m, 39.8 ± 3.6 ft-lb)

10) Loosen the coil spring carefully.

CAUTION:
- Install rear strut with "FWD" or "4WD" mark on strut mount facing outside of vehicle body.
- Insert the protrusion of lower rubber seat into the strut spring seat hole.
