6. Installthe lower arm in the reverse order of
removal, and note these items:
. Be careful not to damage the ball joint boot when
connecting the lower arm to the knuckle.
' Tighten all mounting hardware to the specified
torque values,. Firstinstall all the components and lightlytighten
the bolts and nuts. then raise the suspension to
load it with the vehicle's weight before fully
tightening it to the specified torques.. Torque the castle nut to the lower torque
specification, then tighten it only far enough to
align the slot with the ball joint pin hole. Do not
allgn the castle nut by loosening it.
. Install a new lock pin on the castle nut after
torquing.. Before installing the wheel, clean the mating
surface of the brake disc and the inside of the
wneet.. Check the wheel alignment, and adjustitif
necessary (see page '18-4).

Disassembly/lnspection
1. Compress the damper spring with a commercially
available strut spring 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 necessary to remove the nut,
Release the pressure from the strut spring
compressor, then disassemble the damper as
shown in the Exploded View.

Reassemble all the pans, except for the upper
spring seat and 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, and binding
during these tests.
