UPPER IALL JOINT
REPLACEMENT
1. Position
.
a support between the
upper arm and frame side rail as
shown in Fig16, then, raise the car
and position safety stands.
l. Remove ·the wheel and tire.
3. Remove the cotter pin and nut
from the upper ball joint stud.
4. Position the ball joint remover
tool as shown in Fig.
17.
The tool
should seat
firmly
against the ends
of
both studs, and not against the lower
stud
nut.
It
may
be
necessary to re-
move the lower ball joint cotter pin
if it prevents the tool from seating on
the lower stud.
5. Turn the tool with a wrench
until both studs are under tension,
and then, with a hammer, tap the
spindle near the upper stud to loosen
the stud from the spindle. Do not
loosen the stud with tool pressure
alone. Raise the stud out of the
spindle bore.
6. Drill the three rivets retaining
the ball joint to the upper arm and
remove the ball joint.
7. Clean the end of the arm, and
remove all burrs from the hole edges.
Check for cracks in the metal at the
holes, and replace the arm if it is
cracked.
8. Attach the new ball joint to the
upper arm. Use only the bolts, nuts,
and washers supplied in the kit. Do
not rivet the new ball joint to the
arm. Torque the
nut~
to specification
9. Position the ball joint stud in
the spindle bore, and torque the re-
taining nut to specification. Install a
new cotter pin, tighten the nut if nec-
essary to line up the cotter pin hole.

16 Upper Arm Support
pads integral with the axle housing
rest on a spring plate and rubber
insulator. These are located on two
leaf-type springs. The axle housing
is fastened to the springs by spring
clips (U-bolts), spring clip plates
and nuts. (Figs.
16
and 26.) Each
spring is suspended from the under-
body: side rail by a hanger at the
front and shackle at the
rear:
The
upper end of each shock absorber
is mounted to a bracket in the
.
underbody. The lower end is moun-
ted to the spring clip plate.
The springs and shock absorbers
provide for up and down movement
of the rear axle and wheels as re-
quired by changes in the road sur-
face. They also cushion road shocks.
Falcon vehicles fitted with the
351 CID engine and improved hand-
ling suspension and the GT Falcon
are fitted with rear axle radius rods
to give more positive location under
heavy acceleration.
