The vehicle should be on a level surface before you start.

1. In a few short hours you can update your classic car with new Speedtech
Performance Tubular Lower Control Arms. We recommend you inspect all of
your car's suspension prior to installation of our parts, such as tie rods, ball joints
and other suspension parts which may be worn and could cause adverse effects.
Replace parts as necessary.

2. Jack up and properly support the vehicle's frame. Remove the front wheels.
For cars with drop off style rotors, reinstall one lug nut if needed to prevent the
rotor from falling off.

3. Place the jack under the outer end of one of the lower control arms. Gently
raise the jack to compress the spring slightly and relieve the pressure on the ball
joint. Remove the shock and sway bar links. Attach a coil spring compressor to
the coil and compress the spring enough to remove spring pressure.

4. Removing the spindle from the upper control arm is not necessary, however
doing so may allow you more work room. To do this, remove the cotter pin and
loosen the castle nut until it has approximately 5 threads of contact. Use a pickle
fork if necessary to separate the spindle from the ball joint. Remove the castle
nut. Watch carefully for any tension on the spring that may pop the assembly
apart as the nut is removed.

5. Repeat this process for the lower ball joint. Watch carefully for any tension on
the spring that may pop the assembly apart as the nut is removed. Remove the
coil spring and place aside.

6. Remove the stover nuts and bolts from the mounts that hold the control arm in
the frame and remove the control arm from the frame. Clean, remove rust and
repaint the mounts as needed.

7. Install the new lower control arm in the reverse order. Because of bushing
variations and over tightening as bushings have been replaced in the past, you
may encounter an overly tight fit. If so, you will need to spread the tabs on the
control arm mounts. The best way to do this is to assemble a ½ X 4” length of all
thread with 2 nuts and washers inside the mount. Gently tighten the nuts so that
they spread the mount tabs apart. Test fit the arm periodically, as the mounts may
spring back slightly during this process.
