The two cross-members to body supports are at-
tached to the horizontal part of the cross-member
with two bolts. The oufererbolt serves simultaneously
as support for the lower control arm. As the bolt is
inserted from the front, the cross-member to body
support can be removed without the lower control
arm. The inner bolt attaches simultaneously to the
steering.
The stabilizer is U-shaped and supported in rubber
bushings in the two cross-members to body supports.
The complete front suspension is attached to the
underbody in four places.
The engine damper blocks are bolted to the inside of
the inclined parts of the cross-member.
The front wheel bearings are roller bearings.
All front suspension joints are maintenance-free.
MAINTENANCE AND ADJUSTMENTSFRONT WHEEL BEARING ADJUSTMENT
1. If wheel has not previously been removed from the
car, remove grease cap, cotter pin, and spindle nut.
Discard cotter pin.
2. Torque spindle nut to 18
lb.ft. while rotating
wheel. This will allow the bearings to settle.
3. Back offspindle nut
l/4 turn. If slot and cotter pin
hole are staggered, further back off nut
l/l2 turn,
but do not tighten, until next slot in nut is in align-
ment with hole in spindle. Install new cotter pin. A
properly adjusted wheel bearing has a small amount
of end play and a loose nut when adjusted in the
above manner.

Removal GT1. Prior to raising front end of car, apply parking
brake and block rear wheels.
2. Raise front end of car with a jack. It is recom-
mended that a wood block be placed between thejack and the front cross member to prevent damage
to the cross member.
3. Support front end of car by placing floor standsunde:r jacking brackets.
4. Support engine-transmission assembly in upper-
most position with jack stand at rear of engine, or an
alternate method would be to use Engine Holding

installing fixture. Replace nut and tighten. The en-
gine will now be supported by the tool between the
frame rails.

LOWER BALL JOINT REMOVAL AND
INSTALLATIONNew lower ball joints have an axial play of up to
,020inch. The maximum permissible axial play of older
ball joints is
,080 inch. At an axial play of more than
,080 inch, the lower ball joint must be replaced. If the
dust cap is torn, loose, or missing, the lower ball joint
must also be replaced. See Figure
3A-14.The lower ball joints are checked for wear by using
Checking Gauge J-23402 for the GT, and using
Checking Gauge J-23745 for the Opel 1900
- Manta.
See Figure
3A-15.

4. With a suitable drift, detach ball joint from steer-
ing knuckle. With jack, lift up lower control arm,
unscrew castle nut and remove Hooks J-23697.
5. Unscrew upper control arm ball joint and suspend
front wheel hub and brake caliper in wheel house. Do
not turn upper control arm ball joint flange, as this

CAUTION:
Fasteners are important attachingparts in
that they could affect the performance of
vitaI com-
ponents and systems, and/or could result in
ma&r
repair expense. They must be replaced with one of
the same part
numer or with an equivalent part if
replacement becomes necessary. Do not use a
re-
placement part of lesser quality or substitute design.
Torque values must be used as specified during reas-
sembly to assure proper retention of these parts.1. When pressing the ball joint in place, make certain
the locating notch in the lower rim of the ball joint
matches the alignment reference mark placed on the
lower control arm prior to removal. The notch in the
ball joint bottom plate, identifying the direction of
the elongated slot, must point towards the brake
drum backing plate. See Figure
3A-17. Alignment
must be within 2 degrees of lower control arm center-
line. If proper positioning of the ball joint is not
accomplished, the result is a limitation of the neces-
sary ball stud movement. If ball stud movement is
limited, an interference between the ball stud and
housing is created, and binding or even fracture may
occur. Replacement ball joints may or may not have
marking notch as shown in Figure
3A-20. If it does
not have a marking notch, the joint is completelysymetrical and may be installed in any position.
When pressing in ball joint do not press on bottom
plate, but on ball joint housing only.2. Install dust cap on lower ball joint and fill with
chassis lubricant. Attach dust cap retainer.
3. Press ball joint into steering knuckle. Use
J-9519-3 as installer and J-21690 as a supporting
sleeve.4. Install castle nut on ball joint stud and torque to
40
Ib.ft. Install new cotter pin.
5. Reconnect shock absorber to lower control arm
and torque to 30 lb.ft.
6. Remove spring compressor.
7. Install front wheel, and lower the car.
8. Always check caster and camber after ball joint
replacement.
