1. Make certain the
car is located on a level surface.

2. Place
blocks or
boards under the front wheels to prevent the car
from rolling.

3. Using the floor
jack, raise the
rear of the car, insuring that the jack is positioned
in the
center of the rear cross member (silver/gray in color).

4. Place two
stands under the rear cross member, and SLOWLY lower the
car onto them.
Make sure you have raised the car high enough
to allow plenty of workspace.

5. Locate the rear
spring. There is a bolt on each end (18mm bottom, 13/16\” nut on top),
with a rubber bushing top and bottom. At the top of the bolt,
above the
nut, you will see a small c-clip. This clip must be
removed in order to
get the nut off the top. Use hog ring
pliers or needle nose pliers to
remove the clip.

6. With the c-clip
removed, loosen the top nut
from the bolt.

7. Pull out the bolt
and bushings
from the leaf spring(the leaf spring is NOT under pressure).

8. Cut both bushings
so that the section with the
extension is the only one left. Use a hacksaw
or serrated
knife. ** NOTE: If the car is too low for your personal preference,
you can add back the piece or pieces you cut off **.

9. Once the
are cut, reassemble the bolt, bushings, and nut
through the leaf spring
and A-Arm. Leave TWO threads showing
on top when you re-tighten. It will
seem loose, but when the
car is lowered onto the ground, the weight will
load the
spring. Don�t forget to put the c-clip back on.

10. Lower
the car,
the rear
done !!


1. Make sure the car
in gear to prevent it from rolling.

2. Raise the car with
the jack positioned in the center of the front cross member.

3. Place the two jack
stands under the cross
member, and SLOWLY lower the car onto them.

4. Remove the front
wheels. It may be necessary to slightly loosen the lug nuts
before the
wheels are completely off the ground.

5. Find the front
leaf spring, and with a 10mm
wrench or socket, turn the bolt as if you
were loosening it
(It is reverse threaded so you are actually tightening

6. Turn the bolt until
there is no longer a gap
between the bushing and the bolt. Measure the
exposed threads
to insure the other side is done the same.

7. Put the wheels
back on and lower the car.

NOTE- It may be necessary to
place a board
under the tires so you will be able to remove
the floor jack once the
car is lowered.
