PRECAUTIONS
Creams are available to protect the skin from a con-
dition known as occupational, or contact dermatitis. This
common type of dermatitis is not contagious. Improved
resin formulas in the approved kits have almost elimi-
nated skin irritation. Cream is supplied with the kit for
men who may have a tendency toward skin irritation
from the resins or dust.
The application of these creams is recommended
whenever the Resin Kit materials are used. Generally,
the cream is not required when the plastic solder kit is
being used. Directions for using the cream is as follows:
a. Wash hands clean. Dry thoroughly.
b.
Squeeze about 1/2 inch (or 1/2 teaspoonful) of
#71 cream into palm of hand.
c. Spread evenly and lightly until cream disappears.
Work cream into cuticle, between fingers and
around wrists.
d. Apply second coat, repeating Steps b and c.
e. Hold hands briefly under cold running water to
set cream.
2.
Remove resin mixture from hands as soon as possi-
ble and imperatively before mixture starts to gel.
This can be observed by the action of the material
being used. Resin may be removed with lacquer
thinner by washing in soap and water.
3.
Respirators are recommended when grinding. Also
some minor skin irritation from glass and powdered
cured resin may be evident. Washing in cold water
will help to minimize.
4.
Use a belt sander with a vacuum attachment for dust
control if possible.
5. Resin mixtures may produce toxic fumes and should
be used in well ventilated areas.
6. Be careful not to get any resin material on clothing.
7. Use the right materials for the job. It is important
to use the approved kits because Chevrolet's rigid
quality standards assure you the right material to
do the job. Other materials available may not meet
the required engineering and safety standards.
8. Keep the materials, utensils and work area clean
and dry. These repairs involve chemical reactions,
and dirt or moisture may upset the chemical bal-
ances and produce unsatisfactory results.
9. Before starting repair operations, look for hidden
damage by applying pressure around the damaged
area, looking for hairline cracks and other breakage.
Check for minor damage at other points in the vehi-
cle such as around exhaust pipes, grille, headlamps
and points of wear or rub. Early repair of this
minor damage may prevent major repair later.
PLASTIC SOLDER
KIT
The Plastic Solder Repair Kit is used for minor re-
pairs on the Corvette body. These materials will produce
an easy, quick and lasting repair in the case of small
cracks, surface imperfections and small holes.
1.
Use paint remover or power sander, and remove
finish from damaged area. Carefully inspect for
other areas requiring repair.
2.
Mix the materials (fig. 72).
3.
Apply the material, using a putty knife or rubber
squeegee, Figure 73. Work the material into the
repair and build the material up to the desired

GENERAL DESCRIPTION
CHEVROLET AND CHEVELLE
Frames used on Chevrolet and Cheveile lines are basi-
cally the same, consisting of full length right and left
side members joined laterally by crossmembers. Sev-
eral different frames are used in each line to meet the
various vehicle size and function requirements but the
basic shape for each line remains the same. Differences
between frames in a given line exist only in metal gauge,
part size and numbers of parts necessary to meet the
particular structural requirements of the models
involved.
CORVETTE
The Corvette frame is a rigid perimeter unit, with five
crossmembers. From the rear kick-up forward, trap-
azoidal shaped, closed side members outline and protect
the passenger compartment. At the cowl area, the side
members curve inward in a sweeping "S" shape, to pro-
vide a sturdy foundation for the engine mounts and clear-
ance for front wheel movement. From the kick-up
rearward, box-sectioned side rails provide fore and aft
support for the rear axle and suspension. Lateral sup-
port is provided by five variously shaped welded-in
crossmembers, including the front unit, which formerly
was bolted-in.
CHEVY II AND CAMARO
Underbody alignment checking procedures will be found
in the Body Service Manual.
REPAIR PROCEDURES
CHECKING FRAME ALIGNMENT
Vehicles involved in an accident of any nature which
might result in a "swayed" or "sprung" frame should
always be checked for proper frame alingment in addi-
tion to steering geometry and wheel alignment.
CAR PREPARATION
Preparing the car for the frame alignment check in-
volves the following:
1.
Place the car on level surface.
2.
The weight of the car should be supported at the
wheel locations.
3.
A visual damage inspection should be made to elim-
inate needless measuring. Obviously damaged or
misaligned areas can often be located by sight.
TRAMMING SEQUENCE
When checking a frame for alignment in case of dam-
age,
the first step is horizontal "X" checking with a
tram from similar given points on opposite side of the
frame.
Frame alignment checks on all models should be made
with the tram points set at the center of each locating
point indicated and the cross bar level to insure
accuracy.
When "X" checking any section of the frame, the
measurements should agree within 3/16". If they do not,
it means that corrections will have to be made.
If a tram gauge is not available, the "plumb bob"
method of checking may be used. To assure any degree
of accuracy when using this method, the vehicle should
be on a level floor.
By using this method, it is only necessary to have a
#
piece of cord attached to an ordinary surveyor's plumb
bob.
When measuring the distance between two points,
the free end of the cord should be placed on the reference
point allowing the plumb bob to hang on the floor. A check
mark should be made on the floor just under the tip of
the plumb bob. This operation should be repeated at all
reference points. With these points located on the floor,
they may easily be measured with a rule.
The second step is checking the vertical dimensions
from the datum plane to the points to be trammed. With
the proper settings the tram bar will be on a plane
parallel to that of the frame. The exception to this would '
be when one of the reference locations is included in the
misaligned area; then the parallel plane between the
frame and the tram bar may not prevail. After com-
pletion of the repairs, the tram gauge should be set at
the specified dimension to check the accuracy of the re-
pair operation.
ALIGNMENT REFERENCE POINT DIMENSIONS
Dimensions to holes are measured to dead center of
the holes and flush to the adjacent surface metal.

FRONT WHEEL BEARING ADJUSTMENT
Proper front wheel bearing adjustment has a definite
bearing on the safe operation of a vehicle. Improperly
adjusted front wheel bearings will result in a lack of
steering stability causing wheel wander, shimmy and ex-
cessive tire wear. Very accurate adjustment is possible
because the spindles are drilled both vertically and hori-
zontally and the adjusting nuts are slotted in all six sides.
NOTE:
Wheel bearings should not

2.
While rotating wheel, tighten spindle nut to 12 lbs. ft
torque.
3.
Back off adjusting nut one flat and insert cotter pin.
If slot and pin hole do not line up, back off the adjust-
ing nut an additional 1/2 flat or less as required to
insert cotter pin.
4.
Spin the wheel to check that it rolls freely and then
lock the cotter pin by spreading the end and bending
it around.
NOTE:
Bearings should have zero preload and

REAR SUSPENSION AND DRIVE LINE 4-29
REAR AXLE NOISE DIAGNOSIS
Mechanical failures of the rear axle are relatively
simple to locate and correct. Noise in a rear axle is a
little more difficult to diagnose and repair. One of the
most essential parts of rear axle service is proper
diagnosis.
Ail rear axles are noisy to a certain degree. The
action of transmitting the high engine torque through a
90° turn reducing propeller shaft speed produces noise
in rear axles. This point establishes the need for a line
between normal and abnormal or unacceptable axle
noises.
Slight axle noise heard only at a certain speed or under
remote conditions must be considered normal. Axle noise
tends to "peak" at varying speeds and the noise is in no
way indicative of trouble in the axle.
If noise is present in an objectionable form, loud or at
all speeds, an effort should be made to isolate the noise
as being in one particular unit of the vehicle. Axle noise
is often confused with other noises such as tire noise,
transmission noise, propeller shaft vibration and uni-
versal joint noise. Isolation of the noise as in any one
unit requires skill and experience. An attempt to elimini-
ate a slight noise may baffle even the best of diagnos-
ticians. Such practices as raising tire pressure to
eliminate tire noise, listening for the noise at varying
speeds and on drive, float and coast, and under proper
highway conditions, turning the steering wheel from left
to right to detect wheel bearing noise, will aid even the
beginner in detecting alleged axle noises. Axle noises
fall into two categories: gear noise and bearing noise.
GEAR NOISE
Abnormal gear noise can be recognized since it pro-
duces a cycling pitch and will be very pronounced in the
speed range at which it occurs, appearing under either
"drive," "float" or "coast" conditions. Gear noise
tends to peak in a narrow speed range or ranges, while
bearing noise will tend to remain constant in pitch. Ab-
normal gear noise is rare and usually originates from
the scoring of the ring gear and pinion teeth as a result
of insufficient or improper lubrication in new assemblies.
Side gears seldom give trouble as they are used only
when the rear wheels travel at different speeds.
BEARING NOISE
Defective bearings will always produce a whine that is
constant in pitch and varies with vehicle speed. This fact
will allow you to distinguish between bearing noise and
gear noise.
1.
Pinion bearing noise resulting from a bearing failure
can be identified by a constant rough sound. Pinion
bearings are rotating at a higher speed than differen-
tial side bearings or axle shaft bearings. This
particular noise can be picked up best by testing the
car on a smooth road (black top). However, care
should be taken not to confuse tire noise with bear-
ing or gear noise. If any doubt exists, tire treads
should be examined for irregularities that would
produce such noise.
2.
Wheel bearing noise may be confused with rear axle
noise. To differentiate between wheel bearings and
rear axle, drive the vehicle on a smooth road at
medium-low speed. With traffic permitting, turn
Fig.
74—Scored Hypoid Ring Gear
the vehicle sharply right and left. If noise is caused
by wheel bearings, it will increase in the turns be-
cause of the side loading. If noise cannot be isolated
to front or rear wheel bearings, inspection will be
necessary.
3.
Side bearings will produce a constant rough noise of
a slower nature than pinion bearings. Side bearing
noise will not fluctuate in the above wheel bearing
test.
Failure Analysis
The most common types of rear axle failures are
hypoid gear tooth scoring and fracture, differential gear
fracture. and/or differential bearing failure, and axle
shaft bearing failure.

GENERAL DESCRIPTION
All 1967 models are equipped with a new split brake
system as a safety feature. If a wheel cylinder or brake
line should fail at either the front end or rear end of
the vehicle, the operator can still bring the vehicle to
a controlled stop. The system is designed with separate
hydraulic systems for the front and rear brake using
a dual master cylinder (fig. 1). The design of the master
cylinder is similar to that used on the 1966 Corvette
in that it has two entirely separate reservoirs and outlets
in a common body casting. The front reservoir and outlet
is connected to the front wheel brakes, and the rear
reservoir and outlet is connected to the rear wheel
brakes. Two pistons within the master cylinder receive
mechanical pressure from the brake pedal push rod and
transmit it through the brake lines as hydraulic pressure
to the wheel cylinders. The filler cap is accessible from
inside the engine compartment.
A new brake pipe distribution and switch assembly
is mounted below the main cylinder. The front and rear
hydraulic brake lines are routed from the main cylinder,
through the brake pipe distribution and switch assembly,
to the front and rear brakes as shown in Figure 2. The
switch is wired electrically to the brake alarm indicator
light on the instrument panel. In the event of fluid loss
in either the front or rear brake system the indicator
on the instrument panel will illuminate red. (The indi-
cator will also' be illuminated when the parking brake is
applied.)
On Camaro models equipped with air conditioning, the
rear brake hydraulic line is routed through a pressure
regulator valve mounted on the left frame side rail
(fig. 3). The valve controls the hydraulic pressure to
the rear brakes resulting in the correct pressure balance
between the front and rear hydraulic systems.
The self-adjusting brakes (fig. 4), used on both front
and rear of all models, are the Duo-Servo single anchor
type which utilize the momentum of the vehicle to assist
in the brake application. The self-energizing or
self-
actuating force is applied to both brake shoes at each
wheel in both forward and reverse motion. The brake
shoe linings are bonded to the shoes.
Wheel cylinders are the double piston type permitting
even distribution of pressure to each brake shoe. To
keep out dust and moisture, both ejads of each wheel
cylinder are sealed with a rubber booC The wheel
cylinders have no adjustments.
The Chevrolet, Chevelle, and Camaro parking brakes
have a foot operated ratchet type pedal mounted to the
left of the steering column. A cable assembly connects
the pedal to an intermediate cable by means of an equal-
izer, where the adjustment for the parking brake is
incorporated. The intermediate cable attaches to the
