Front lower control arm instructions
Parts list:

Fully assembled right lower arm
Fully assembled left lower arm
Installation will require jack stands, floor jack, spring compressor,
and related hand tools. A Service manual will also have a procedure
detailed on removing the lower control arm. The procedure we use is as
follows.
- Make sure the car is in park or in gear and set the parking brake.
We also block the rear wheels. Raise the front and support the car
with jack stands under the frame rails. Make sure you raise the car up
high enough so the lower arm can swing down to the ground without
touching the ground.
- Remove the shock absorbers.
- Install an inside spring compressor up through the lower arm
and compress the spring.
- Remove the lower ball joint cotter pin and nut.
- Use the floor jack and place the jack under the spring pocket
offset towards the ball joint side. Raise the jack up until the upper
control arm rises up off the frame and bump stop. Use a suitable
pickle fork and separate the lower ball joint from the spindle. When
the spindle separates, the lower arm assembly with spindle will drop
off the ball joint.
- Raise the upper arm and spindle assembly up and slide a 2x4 up
between the frame and upper arm. This will hold the assembly out of
the way so you can work on the lower.
- Lower the floor jack and remove the coil spring.
- With the spring removed go ahead and unbolt the lower control arm
from the frame.

- Install the lower control arm. The lower control arm is
pre-assembled. There is a right and a left. The easiest way to tell
which is left or right is by the sway bar attachment bracket welded to
the control arm. The sway bar attachment goes to the front of the car.
In the kit there are 4 gold spacers. One spacer goes on each side of
the bearing. (See photo). In the kit you will also see a plastic
dowel. The dowel will help facilitate installing the control arms in
the frame. Take the dowel and push it through the bearing in the
control arm. Place on the dowel one steel spacer on each side of the
bearing. The taper on the spacer should be that the narrowed end goes
next to the bearing. The dowel will hold the spacers in place when you
install the control arm up into the frame.
- Install the control arm up into the frame. Take the
stock
eccentric lower arm bolt and install it through the frame and lower arm
assembly. This will push out the dowel through the frame hole and also
help align the bearing in the frame. The dowel will drop out and should
be used on the other side for installation. Keep the dowel in your
toolbox. You may need it someday. With the eccentric bolt through the
frame, finish stalling the eccentric cam washer and hardware. Position
the eccentric by rotating the bolt until the bolt appears to be about in
the middle of the slot. Torque the 9/16 bolt to 120 foot-pounds.
- Install the strut rod next onto the lower control arm. The strut
rod will index on the tubular arm just as it did on the stock unit.
Torque the bolts to 65 foot-pounds.

- The next step is to reinstall the spring. There is a coil spring
cushion that rests
in the spring pocket of the lower control arm. The
cushion has a place where the coil spring will index. When you place
the spring up into the frame, there is an index just like what is
shown in the spring cushion. Install the spring at this time.
- Index the upper part of the spring first and then swing the lower
arm up to the spring. Rotate the spring cushion until the cushion will
index with the spring.
Use a floor jack under the lower control arm to
help hold the arm close to the spring. The floor jack should be
positioned towards the ball joint side, not directly under the spring
pocket. Slowly raise the floor jack and slip the spring into the spring
cushion. Sometimes you may need a pry bar to help guide the spring into
the cushion.
- Raise the lower arm high enough to re install the spindle. Remove
the 2x4 holding the upper arm up and line the spindle up to the ball
joint. Lower the spindle so the ball joint drops in. Install the lower
ball joint nut and tighten to 80 to 90 foot-pounds. Install the cotter
pin.
- Remove the spring compressor from inside the coil spring.
- Reinstall the shocks.
- Lubricate the lower ball joint. (Note: The bearing does not require
grease).
- Use the same procedure on the other side.
- The car will require realignment after installation.
