INSTRUCTIONS
1. With the front wheels securely blocked, raise the rear of the vehicle to an
adequate working height, then support the vehicle / chassis / body securely
leaving the differential slightly supported with the jack. Place the jack under the rear
axle to support but do not lift.
2. Remove the rear wheels and then remove the bolts that retain the lower shock
absorber mounts. If you have a Quad-Shock equipped car remove the nuts on the
frame side of the axle dampening shock and pull it from the pivot.
3. Gradually lower the differential as far as possible (be very careful not to over
extend the flexible brake line that runs from the chassis to the rear end.). At this
point there should be little or no tension on the rear springs so they can be easily
removed from the car allowing the easiest and safest control arm installation
possible. NOTE – pay attention to the position of the cutoff spring end and be sure to
re-install the springs clocked in the same position as this will affect ride height and
ride quality.
4. Unbolt the rear sway bar from the lower control arms and remove the sway bar.
5. Working on one side of the car at a time, remove the two trailing arm pivot bolts.
The front pivot bolt has very limited clearance between the muffler and frame rail,
but can be reached with a deep socket and ratchet combination. Remove the old
control arm. Be sure to only remove and install one control arm at a time, failure to
do so will let the rear end housing rotate and will make your installation much more
difficult.
