FRONT SUSPENSION - Spring and Strut Assembly
I nspl
Wash all parts, except for nonmetallic parts,
clean with suitable solvent and dry with com-
pressed air.
a Blow dirt and dust off of nonmetallic parts
using compressed air
a. Oil oozing out around gland packing does not
call for strut replacement.
If oil leakage
is evident on spring seat, check
piston rod and gland packing to correct
the
cause of problem.
If oil leakage occurs on welded portion of
outer strut
casing, replace strut assembly.
b. If shock absorber itself is malfunctioning,
replace
as shock absorber kit (including piston
rod, cylinder, bottom
valve and guide bushing).
INNER CYLINDER AND OUTER CASING
a Inspect inner cylinder and outer casing for
cracks, deformation or other damage. For inner
cylinder damage, replace shock absorber. For
outer casing damage, replace strut assembly

STRUT MOUNTING INSULATOR
Replace if cemented rubber-to-metal portion are
melted or cracked. Rubber parts should also be
replaced, if deteriorated.

Replace if inspection reveals abnormal noise or
excessive rattle in axial direction

Before assembly, keep away from dust to prevent
entry of dust.
Use "NISSAN GENUINE STRUT FLUID" or
equivalent.
Oil capacity
is very important since performance of
strut varies with amount of fluid in strut.
Add correct amount of fluid

TRANSVERSE LINK AND LOWER BALL JOINT
Removal ar
Separate knuckle arm from tie-rod using Tool.
SFA575
Separate knuckle arm from strut. Remove
stabilizer, tension rod and transverse link
SFA576
Separate ball joint from knuckle arm using
press
SFA577
Installation
To install transverse link, first temporarily
tighten nuts securing transverse
link spindle
which connects transverse
link to suspension
cross member.
Final tightening should be carried out at curb
weight with tires
on ground.
Make sure mating surface of bushing
is clean
and free from oil and grease.

Inspection
Refer to Front Suspension (Spring and Strut

0 Carefully insert the shock absorber cartridge
into the outer strut tube.
CAUTION:
Do not drop the shock absorber or otherwise
mishandle
it.
SFA165
After the shock absorber has been inserted
into the outer tube, gently shake the strut
assembly right and left
so that the shock
absorber
is centered.
Install gland packing and tighten the gland
packing with the Gland Packing Wrench and
a torque wrench
Refer to Spring and Strut Assembly for assembly
Be careful not to damage the piston rod during
tightening.
