FRONT AXLE - Wheel Hub
Preload Adjustment

After wheel bearing has been replaced or front
axle
has been reassembled be sure to adjust wheel
bearing preload
as described below
1. Before adjustment, thoroughly clean all parts
to prevent
dirt entry.
2 Apply recommended multi-purpose grease
sparingly to the following parts
Threaded portion of spindle
Contact surface between lock washer and outer
wheel bearing

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

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.
