STEERING COLUMN
ALIGNMENT
THUNDERBIRD AND
CONTINENTAL MARK III
A condition of high shift or steering
efforts may be experienced caused by
improper alignment of the energy ab-
sorbing steering column. The fol-
lowing procedures outline the steps
necessary to correctly re-align either
fixed or tilt columns.
It is recommended that before at-
tempting realignment, the toe plate
(column retainer) to dash panel fas-
tener holes be inspected for a binding
or misaligned condition.
If the conditions described above
could be attributed to this area, file or
ream the dash panel holes for greater
clearance.
The column alignment procedures:
1.
Loosen the nuts retaining the toe
plate (column retainer) to the dash
panel (B in Fig. 8).
2.
Loosen to fingertight the bolt
and nut located on the toe plate re-
taining clamp (C in Fig. 8).
3.
Remove trim at instrument panel
to steering column mounting to ex-
pose retaining bolts.
4.
Loosen to fingertight {.he bolts
that support the column and bracket
against the instrument panel (D in
Fig. 8).
5.
Loosen to fingertight the bolts or
nuts which retain the column brackets
to the brake pedal support bracket
(E).
6. Loosen to fingertight the bolt
which controls lateral adjustment of

tube.
In some instances the column
will shift into proper alignment when
the toe plate attaching nuts are loos-
ened. (Alignment is acceptable if a
.010 inch feeler blade can be passed
freely, completely around the area be-
tween the outer diameter of the steer-
ing shaft and the shift tube.) if the
misalignment condition can be attrib-
uted to this area, file or ream the dash
panel holes for greater clearance. If
the alignment is maintained after the
toe plate nuts and toe plate to column
clamp bolt and nut are torqued to the
8-12 ft-lb specification, no further ad-
justment is necessary.
4.
Remove instrument panel lower
trim panel. Vehicles equipped with a
combination radio stereo tape player
will require removal of the radio and
tape player assembly in order to gain
access to the upper R.H. steering col-
umn support bracket bolt.
5.
Loosen the seven bolts at the
steering column support bracket and
brake pedal support bracket.
6. Install a 3/16 inch diameter rod
spacer in the flex coupling to assure
proper clearance between upper and
lower steering shaft.
7.
Raise the vehicle, remove the
transmission splash shield, and visual-
ly align the column to center the
steering shaft in the column. Tighten
two toe plate attaching nuts sufficient-
ly to hold the column alignment (two
persons may be required for this oper-
ation).
8. Lower the vehicle.
9. Check the clearance between the
steering column support bracket and
the instrument panel bracket. It may
be necessary to add shims (Part Num-
ber MK-3054-A .060 inch thick, or
C3AZ-3054-A, .113 inch thick) be-
tween the support bracket and the in-
strument panel bracket to prevent
movement of the column when the
support bracket bolts are tightened.
10.
Loosen the two toe plate at-
taching nuts previously tightened. Re-
check steering column alignment. In
some instances it may be necessary to
enlarge the holes in the dash panel in
order to obtain proper column align-
ment.
11.
With the column properly al-
igned, torque the four toe plate at-
taching nuts to 4-9 ft-lbs.
12.
Torque the toe plate to steering
column clamp bolt to 3-5 ft-lbs.
13.
Recheck steering shaft to shift
tube alignment. A 0.10 inch feeler
blade should pass freely, completely
around the area between the outer di-
ameter of the steering shaft and shift-
er tube.
14.
Raise the vehicle.
15.
Adjust transmission shift link-
age.
16.
Install transmission splash
shield.
17.
Lower the vehicle.
18.
Install the radio stereo tape
player if so equipped.
19.
Install instrument panel lower

cation. Continue to tighten each nut
until the slots in the nut align with the
hole in the stud. Then install a new
cotter pin.

On all vehicles except Lincoln
Continental models, place the idler
arm and the front wheels in the
straight ahead position to insure keep-
ing the steering wheel aligned and to
prevent bushing damage after the at-
taching nut has been torqued. Insert
the center link stud through the hole

and minimum backlash between sector
gear and ball nut. There are only two
possible adjustments within the recir-
culating ball-type steering gear, and
these should be made in the following
order to avoid damage or gear failure.
1.
Disconnect the Pitman arm from
the steering Pitman-to-idler arm rod.
2.
Loosen the nut which locks the
sector adjusting screw (Fig. 3), and
turn the adjusting screw counterclock-
wise.
(On models equipped with the
Cobra Jet engine, it may be necessary
to use a suitable holding tool with an
extension and a long screwdriver to
make the gear adjustment).
3.
Measure the worm bearing pre-
load by attaching an in-lb torque
wrench to the steering wheel nut (Fig.
4).
With the steering wheel off center,
read the pull required to rotate the
input shaft approximately 1 1/2 turns
either side of center. If the torque or
preload is not within specification
(Part 3-1), adjust as explained in the
next step.

4.
Loosen the steering shaft bearing
adjuster lock nut, and tighten or back
off the bearing adjuster (Fig. 1) to
bring the preload within the specified
limits.
5.
Tighten the steering shaft bear-
ing adjuster lock nut, and recheck the
preload.
6. Turn the steering wheel slowly to
either stop. Turn gently against the
stop to avoid possible damage to the
ball return guides. Then rotate the
wheel 2-3/4 turns to center the ball
nut.
7.
Turn the sector adjusting screw
clockwise until the specified torque
(Part 3-13) is necessary to rotate the
worm past its center (high spot) (Fig.
1).
8. While holding the sector adjust-
ing screw, tighten the sector adjusting
screw locknut to specification, and re-
check the backlash adjustment.
9. Connect the Pitman arm to the
steering arm-to-idler arm rod.

REMOVAL AND INSTALLATION
STEERING GEAR
REMOVAL
1.
Remove the bolt(s) that retains
the flex coupling to the steering shaft.
2.
Remove the nut and lock washer
that secures the Pitman arm to the
sector shaft using Tool T64P-3590-F
(Fig. 5).
3.
To obtain clearance on some
models equipped with standard trans-
mission, it may be necessary to dis-
connect the clutch linkage. On some
8-cylinder models, it may be necessary
to lower the exhaust system.
4.
Remove the steering gear-to-side
rail bolts and remove the gear.

and torque the steering gear-to-side
rail bolts to specification (Part 3-13).
2.
If the clutch linkage has been
disconnected, reposition, install and
adjust it. If the exhaust system has
been lowered, reinstall it to its proper
position.
3.
Position the Pitman arm and the
sector shaft and install the attaching
nut and lock washer. Torque the nut
to specification.

1. Rotate the steering shaft 3 turns
from either stop.
2.
After removing the sector adjust-
ing screw locknut and the housing
cover bolts (Fig. 6), remove the sector
shaft with the cover. Remove the
cover from the shaft by turning the
screw clockwise. Keep the shim with
the screw.

6. Turn the ball nut over, and ro-
tate the worm shaft from side to side
until all 50 balls have dropped out of
the nut into a clean pan. With the
balls removed, the ball nut will slide
off the worm.
7. Remove the upper bearing cup
from the bearing adjuster and the
lower cup from the housing. It may be
necessary to tap the housing or the
adjuster on a block of wood to jar the
bearing cups loose.

4.
Insert the ball guides into the
holes of the ball nut, tapping them
lightly with a wood handle of a screw
driver if necessary to seat them.
5.
Insert 25 balls into the hole in
the top of each ball guide. It may be
necessary to rotate the shafi: slightly
one way, then in the opposite direc-
tion to distribute the balls in the cir-
cuit.
6. After the 50 balls are installed,
install the ball guide clamp. Torque
the screws to specification. Check the
worm shaft to make sure that it ro-
tates freely.
7. Coat the threads of the steering
shaft bearing adjuster, the housing
cover bolts, and the sector adjusting
screw with a suitable oil-resisi:ant seal-
ing compound. Do not apply sealer to
female threads and especially avoid
getting any sealer on the steering shaft
bearings.
8.
Coat the worm bearings, sector
shaft bearings, and gear teeth with
steering gear lubricant.
9. Clamp the housing in a vise, with
the sector shaft axis horizontal, and
position the steering shaft lower bear-
ing in its cup.

Position the steering shaft and
ball nut assemblies in the housing.
