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.

GENERAL DESCRIPTION

CHEVROLET

The link type rear suspension (fig. 1) has two lower

control arms which maintain proper axle to frame re-

lationship and also take the acceleration, drive and

braking forces. A single upper control arm on light-

duty models (or two upper control arms on heavy-duty

models and all station wagons) limits axle rotation when

drive, acceleration or braking forces are applied. Lateral

movement of the axle is restricted by the axle-to-frame

tie rod. Two full coil springs and two direct, double
acting shock absorbers are provided for additional ride

control.

CHEVELLE

The rear suspension (fig. 2) is of the four-link design

utilizing axle mounted, full coil springs and direct,

double-acting shock absorbers.

Two rubber-bushed lower control arms, stretching

slightly outboard from axle-mounted brackets to frame

side member mounted brackets, maintain fore and aft
