A" SELF-LOCKING NUT REMOVAL
1. Use the special tools to compress the coil spring.
Caution
(1) Do not tighten the special tool bolt too tight. The
special tool will be broken if the allowable
tightening torque of 74 N·m is exceed.
(2) Install the special tools evenly, and so that the
maximum length will be attained within the
installation range.
(3) Do not use an impact wrench as it will cause the
bolt of the special tool to be seized.
2. Using the special tools, loosen the self-locking nut.
Caution
To prevent the piston rod lock nut inside the strut
from loosening, do not use an impact wrench when
the self-locking nut is loosened.

bolt of the special tool to be seized.
4. Align the hole in the strut assembly lower spring seat
with the hole in the upper spring seat.
NOTE
Using a pipe as shown facilitates the alignment.
5. Correctly align both ends of the coil spring with the grooves
in the spring seat, and then loosen the special tools.
6. Using the special tools, tighten the self-locking nut to the
specified torque.
Specified torque: 60 ± 10 N·m
Caution
To prevent the piston rod lock nut inside the strut
from loosening, do not use an impact wrench when
the self-locking nut is tightened.
7. After tightening self-locking nut, fill the multi purpose
greese to the bearing part of strut insulator.
