I am replacing the lower control arm and ball joints on a 1997

Resolved Question:

I am replacing the lower control arm and ball joints on a 1997 Mercury Grand Marquis. Using a floor jack and pickle fork I lowered the control arm and removed the shock and coil spring. I am unable to reinsert the coil spring back into the auto. Is there some secret way to do this? I replaced the lower control arms and ball joints on a 1995 Mercury Grand Marquis and the ball joint slipped right back in.

here's the instructions on the spring removal and replacement.

Spring

Removal

  1. Raise vehicle on a hoist. Remove wheel and tire assembly.

  2. Remove the two bolts retaining the front shock absorber (18124) to the front suspension lower arm (3078).

  3. Remove the upper nut, retainer and grommet from the front shock absorber. Remove the front shock absorber.

  4. Remove steering center link from pitman arm.

  5. Support the vehicle with safety stands under the jacking pads and lower the hoist but maintain sufficient working room.

  6. Using Coil Spring Compressor D78P-5310-A or equivalent, install one plate with the pivot ball seat facing downward into the coils of the front coil spring (5310). Rotate the plate so it is flush with the upper surface of the front suspension lower arm.

  7. Install the other plate with the pivot ball seat facing upward into the coils of the front coil spring. Insert the upper ball nut through the coils of thefront coil spring so nut rests in the upper plate.

  8. NOTE: This pin can only be inserted one way into the upper ball nut because of a stepped hole design.

    Insert the compression rod into the opening in the front suspension lower arm, through the upper and lower plate and upper ball nut. Insert the securing pin through the upper ball nut and compression rod.

  9. With the upper ball nut secured, turn the upper plate so it walks up the coil until it contacts the upper front spring insulator (5415). Then back-off one-half turn.
    Install the lower ball nut and thrust washer on the compression rod and screw on the forcing nut.

Do you know who the manufacturer of spring compressor part # XXXXX is?
Expert:  lostrider replied 4 years ago.
That would be OTC, but that may be a little hard to find, but if there is an Auto Zone near you they have a loan a tool program and may have something compatible.
