Disconnect the wiring harness located near the battery that supplies power to the deck
lid lock solenoid from the deck lid (if equipped).
Disconnect the radio static grounding wire on the air cleaner side of the deck lid (if
Mark the orientation of the deck lid to the hinges using tape, a marker, etching device,
etc. to allow for proper alignment of the deck lid upon re-installation.
Remove the deck lid by removing the two bolts on each side that hold the deck lid to the
hinges using a 13MM socket.
Tape large squares of wood onto the rear window glass just behind the hinges as a
precaution to prevent the deck lid hinges from smashing through the glass as tension is
released from the hinges.
Mark the orientation of the hinge bolts to the hinge using paint, an etching device,
etc. to allow for proper alignment of the hinges to the hinge support bracket upon
Notice the shape of the torque rods. The torque rods have squared off open loop
("U" shaped) end's on the opposite end of the hinge linkage. This "U"
end goes underneath and in between the sides of the hinge support bracket and rests
against the torque rod retaining pin that passes through the hinge support bracket. Three
rates of tension can be created using the three hole settings on each bracket to vary the
tension rates of the rods. Normally, this solid pin is in the middle of the three holes.
This pin needs to be removed to release most of the tension created in the torque rod.
This can be done using nylon rope that is looped around the bottom of the loop at the
"U" end of the torque rod. . We have found that the person who will be pulling
the rope rearward to release the tension should wear gloves to protect their hands and
wrap the rope securely around each hand. Then, place one foot against the forward trunk
well for leverage as you pull rearward to release the tension of the rod in order to
remove the pin. Start by removing the driver's side pin. With your assistant firmly
pulling the rope towards the rear of the car, the torque rod "U" end will begin
to be pulled rearward to allow the pin to be pulled out from the hinge support bracket Be
very cautious with this step - for if the rope slips and your fingers are in the way, the
tension of the torque rod will smash your fingers into the firewall. Make certain your
partner has a firm, steady grip on the rope before you move your fingers in place to
remove the pin. Once the pin is pulled out, slowly release the hold on the rope to gently
allow the torque rod to rest against the firewall.
Follow the same steps that are in #7 to remove the torque rod retaining pin from the
Please be aware that there is still quite a bit of tension built up in the torque rods
even though the pins have been removed. The next step is to remove the deck lid hinges
with the torque rods still connected to them, as a unit. Begin by loosening the lower nut
holding the hinge to the hinge support bracket on the passenger's side using a 13MM
socket. Do not remove the lower nut entirely, just loosen it a few turns at this time.
Next, loosen the upper nut holding the hinge to the hinge support bracket using a 13MM
socket. Slowly loosen this upper nut all the way to remove it - be aware that tension is
being released as you slowly loosen these nuts.
Now that the upper nut has been removed, the lower nut now needs to be removed. Slowly
remove the lower nut holding the hinge to the hinge support bracket. Be careful because
once this nut is removed, the tension will be fully released from this rod - keep hands
clear from the hinge to prevent injury.
The torque rod is held in position in two places. The first place is on the side of the
hinge support bracket where a "C" shaped hook holds the torque rod in place. The
second place is on the opposite end of the torque rod where it slides behind a lip on the
hinge support bracket. Once the nuts holding the hinge in place have been removed, work
the torque rod free from these two points to remove the torque rod from the Fiero. NOTE:
you may need to use a screwdriver to pry the torque rod out of the "C" hook if
the tolerance is too close. Once removed, label this torque rod "#1 Passenger
Side" and set aside. Notice that this torque rod has a rubber cushioning sleeve
wrapped around it to prevent it from rubbing with the other torque rod.
Repeat steps 9, 10, and 11 to remove the torque rod connected to the driver's side
hinge. Once removed, label this one "#2 Driver Side" and set aside.
Looking at the torque rod/hinge assemblies you just removed, notice the Torx bit screw
head which holds the torque rod to the hinge. The bit needed to remove this screw is a
special theft deterrent bit because it has a center piece to prevent using a standard Torx
bit to remove it. These special Torx bits are available from your local Trak Auto parts
store - other parts stores should have them as well. The part number for this seven piece
set is #26000 from Lisle Corp. and cost about $12.99. Using the #T-40 size bit, loosen the
bolt securing the torque rod from the hinges on both the #1 and #2 rods. If you want to,
repaint the hinges and torque rods for that "new, factory" look.
Match up the new torque rods with the old torque rods labeled #1 and #2 to make sure you
are installing the correct bar to the correct hinge. Apply grease to the contact points
where the screw holds the torque rods to the hinge to prevent wearing.
It would also be recommended to apply grease to the contact points that hold the torque
rods in place - both the "C" hook and the lip that are both located on the sides
of the hinge support brackets.
We are now ready for the re-installation of the torque rod/hinge assemblies. The first
assembly to re- install is the one labeled "#2 Driver Side" (because this one
was the last one removed). This step requires two people. First, position the assembly so
that the torque rod fits into the "C" hook on the passenger side hinge support
bracket making sure the hinge aligns up with the screws in the hinge support bracket while
aligning the torque rod to fit behind the lip on the driver's side hinge support bracket -
and at the same time, aligning the "U" loop on the end of the torque rod up and
in between the sides of the driver's side hinge support bracket. This step is as
complicated and difficult as it sounds because you are trying to align four things at the
While having your assistant tightly hold the torque rod in position, pull down firmly on
the deck lid hinge to align the hinge with the hinge support screws. Position the hinge in
place so you can screw on the lower retaining nut to hold the hinge in position. Tighten
this nut down making sure it aligns with the marks you placed on the hinge when you
removed the retaining nuts. Be careful and hold firmly because you are now building
tension in the torque rod. With the alignment correct, re-install the upper retaining nut
and then tighten both nuts securely. Verify the torque rod is correctly positioned.
Now you are ready to install the "#1 Passenger Side" torque rod. Follow the
same steps in #16 and #17 as you did for the "#2 Driver Side" torque rod.
Verify the torque rods are seated in the "C" hook and up in back of the lips
on the hinge support brackets. Verify that the four hinge nuts are securely tightened. We
are now ready to add more tension to the rods by setting the torque rods on the pins.
Generally, a good place to insert the torque rod pins is in the middle hole of the three
located on the hinge support brackets.
Review step #7. This step requires two people. Loop the nylon rope around the bottom of
the "U" end of the torque rod on the passenger side. Have your assistant pull
firmly back on the torque rod until you can insert the pin into the middle hole on the
side of the hinge support bracket.. Insert the pin and cautiously release the rope's
tension to allow the torque rod to rest on the pin. Be very cautious with this step - for
if the rope slips and your fingers are in the way, the tension of the torque rod will
smash your fingers into the rear firewall.
Repeat step #20 for the driver's side pin insertion.
You are now ready to re-place your deck lid. Make sure you properly aligned the deck lid
with the hinges using the alignment marks you have made on the deck lid. Re-install the
four bolts which secure the deck lid to the hinges - two on each side.
Re-connect the radio static grounding wire located on the air cleaner side of the deck
Re-connect the wiring harness for the power deck lid lock solenoid on the battery side
of the deck lid (if equipped).
Slowly lower the deck lid to test the newly installed torque rods and make sure the deck
lid is properly aligned with the rest of the body panels.
If you were successful, your deck lid will stay up all by itself as you raise it - no
more prop rods, no more lumps on your head. Enjoy!
