(cont'd)
9. Remove the hub bearing unit (A) from the spindle.
Install the hub bearing unit in the reverse order of
removal, and note these items:
. Tighten all mounting hardware to the specified
torque values,. Before installing the brake disc, clean the mating
surface ot the hub and the inside of the brake
disc.. Use a new spindle nut on reassembly.. After tightening, use a drift to stake the spindle
nut shoulder against the spindle.. Use a new hub cap on reassembly.. Before installing the wheel, clean the mating
surface of the brake disc and the inside of the
wneel.

Damper/Spring Replacement (cont'dl
Disassembly/lnspection
1. Compress the damper spring with a commercially
available strut compressor (A) according to the
manufacturer's instructions. then remove the self-
locking nut (B)while holding the damper shaft (C)
with a hex wrench (D). Do not compress the spring
more than necessarv to remove the nut.
Release the pressure from the strut spring
compressor, then disassemble the damper as
shown ln the Exploded View.
Reassemble all the pans, except for the spring.
Compress the damper assembly by hand, and
check for smooth operation through a full stroke,
both compression and extension. The damper
should extend smoothly and constantly when
compression is released. lf it does not, the gas is
leaking and the damper should be replaced.

Check for oil leaks, abnormal noises, or binding
during these tests.
