INSTALLATION INSTRUCTIONS
1. This installation should only be performed by an experienced mechanic. Improper coil
spring removal and installation can result in serious injury. If you are not experienced
in this type of installation we recommend you have the installation performed by a
professional mechanic at a commercial garage and/or alignment shop.
2. Begin by jacking up the front of the vehicle and then place jack stands under the
frame to safely support the vehicle. The front wheels need to be off of the ground.
3. Remove both front wheels.
4. On The Driver's Side Only: Remove the top front shock's mounting nut, bushing and
washer. Remove the two lower shock t-bar mounting bolts and then remove the front
shock through the bottom of the a-arm.
5. Remove the front sway bar end link from the a-arm and the sway bar and discard.
6. Turn the spindle all the way in one direction for easier access to the lower ball joint.
Remove the cotter pin from the castle nut on the lower ball joint. Then loosen the
castle nut, but do NOT completely remove it. Using a hammer, hit the spindle around
the ball joint mounting hole until the ball joint pops loose. You may need to use a
pickle fork.
7. Position a jack under the a-arm in the area of the ball joint. Jack up on the a-arm until
there is no tension on the ball joint.
8. Insert an internal spring compressor through the bottom of the a-arm and up through
the inside of the coil spring. Fully compress the spring using the internal spring
compressor (we recommend using our Part# FCSC1 internal coil spring compressor
that is designed specifically for the G-Body application. It makes the job VERY easy!).
9. Remove the castle nut from the lower ball joint.
10. Place a block of wood underneath the front upper a-arm to support and hold the upper
a-arm, spindle, brakes, etc. up in the car. You can also tie this assembly up, but a
block of wood placed between the frame and the underside of the upper a-arm works
great.
11. Carefully lower the jack you placed underneath the lower a-arm and lower the a-arm
as far as it will come down. Hold onto the spring and remove it when it is free as you
lower the a-arm.
12. While holding onto the a-arm, remove both of the mounting bolts that go through the
a-arm bushings at the frame mounts and then remove the a-arm from the vehicle.
13. Lightly sand and/or wire wheel the insides of the frame mounts where the a-arm
bushings ride. When you have removed all dirt, rust and scale from these mounting
areas apply a liberal amount of grease to these areas of the mounts. See the end of
these instructions for information on what type of grease must be used.
14. Properly identify the left side Spohn Performance front lower a-arm. The sway bar end
link and polyurethane bump stop face the FRONT of the vehicle when installed.
