DISASSEMBLYNJSU00101. Set shock absorber on vise, thenloosenpiston rod lock nut.
+Do not remove piston rod lock nut at this time.
2. Compress spring with Tool so that shock absorber mounting
insulator can be turned by hand.
WARNING:
Make sure that the pawls of the two spring compressors are
firmly hooked on the spring. The spring compressors must be
tightened alternately so as not to tilt the spring.

Precautions
PRECAUTIONSNJSU0024+When installing each rubber part, final tightening must be
carried out under unladen condition* with tires on ground.
Oil will shorten the life of rubber bushes. Be sure to wipe
off any spilled oil.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
+Use flare nut wrench when removing or installing brake
tubes.
+After installing removed suspension parts, check wheel
alignment.
+Do not jack up at the trailing arm and lateral link.
+Always torque brake lines when installing.
+Lock nuts are unreusable parts; always use new ones.
When replacing, do not wipe the oil off of the new lock nut
before tightening.
