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.

CHEVROLET CHASSIS SERVICE MANUAL

FRONT SUSPENSION 3-5

FRONT END ALIGNMENT

Front end alignment, that is alignment of the inter-

related steering components of the front suspension sys-

tem, must be correctly maintained to assure ease and

stability of steering and satisfactory tire life.

Alignment Preliminary Steps

Several different types of machines are available for

checking all the factors of front end alignment. The in-

structions furnished with each particular machine should

be followed. In all cases, however, checks should be

made with the vehicle level and at curb weight.

Since steering complaints are not always the result of

improper alignment a check should be made to see if any

of the following conditions exist. Any such conditions

should be corrected before proceeding further.

1.
Steering gear loose or improperly adjusted.

2.
Steering gear housing loose at frame.

3.
Excessive wear or play in spherical joints or steer-

ing shaft coupling.

4.
Tie rod or steering connections loose.

5.
Improper front spring heights.

6. Unbalanced or underinflated tires.

7.
Improperly adjusted wheel bearings.

8. Shock absorbers not operating properly.

Wheel alignment should always be made with the vehi-

cle rolled forward taking out any slack in the same man-

ner as when the vehicle is traveling forward.

Caster and Camber Adjustment

NOTE: Before adjusting caster and camber

angles, the front bumper should be raised and

quickly released to allow car to return to its

normal height.

Chevelle, Camaro and Corvette

Caster and camber adjustments are made by means of

shims inserted between the upper control arm inner sup-

port shaft and the support bracket attached to the frame

(fig. 6). Shims may be added, subtracted or transferred

to change the readings as follows:
Fig.
6 - Caster and Camber Adjustment - Chevelle

Typical of Corvette and Camaro

Caster - change shims at either the front or rear of

the shaft.

The addition of shims at the front bolt or removal

of shims at the rear bolt will decrease positive

caster. One shim (1/3 2") will change caster (ap-

prox.) 1/4°.

Camber - change shims at both the front and rear of

the shaft.

Adding an equal number of shims at both front and

rear of the support shaft will decrease positive cam-

ber. One shim (1/32") at each location will move

camber (approx.) 1/5° (Chevelle and Camaro); 1/6°

(Corvette).

not the vehicle riding height is correct.

1.
Place the vehicle on a smooth, level floor and bounce

and rock the front end several times. Raise vehicle,

then allow it to settle to a normal height.

2.
Measure the following two distances (fig. 9):

a. From the floor to the center of the inner pivot of

the lower control arm. (On the Chevrolet and

Camaro, this measurement must be made at the

rear end of the pivot.)

b.
Chevrolet--Measure the distance from the floor

to the lower face of the lower steering knuckle

boss for the spherical joint on the same side of

the vehicle.

Chevelle—From the floor to the outer pivot

which is located 1/8" (.12) inboard from the ball

stud boss at the lower surface of the arm.

Chevy II--Measure the distance from the floor

to the lower ball joint seat.
Corvette—Measure the distance from the floor

to the lower face of the lower steering knuckle

boss for the spherical joint on the same side of

the vehicle.

Camaro—From the floor to the lower inboard

edge of ball seat.

3.
The difference between these two measurements

should be as outlined in the Specifications given at

the end of the book with the vehicle at curb weight

(full tank of gas, spare tire and jack in trunk, no

passengers).

4.
Measure the opposite side of the vehicle in the same

manner. The measurements for both sides should

differ no more than 1/2".

5. To correct the height, springs must be replaced.

These springs do not have flat ends and shims should

not be used.

the coil spring from the lower control arm.

8. Installation is the reverse of the above procedure.

Carefully follow instructions for installing spring

tool.

LOWER CONTROL ARM SPHERICAL JOINT

Chevrolet, Chevelle, Comoro and Corvette

Inspection

The lower control arm spherical joint should be re-

placed whenever wear is indicated in the upper joint

inspection.

NOTE: The lower control arm spherical joint

is a loose fit in the assembly when not connected

to the steering knuckle.

Only if inspection of each upper joint indicates them

both to be within limits, inspect each lower joint for ex-

cessive wear as follows:

1.
After reconnecting upper joints to steering knuckles,

support vehicle weight on wheels or wheel hubs.

2.
With outside micrometer or caliper, measure dis-

tance from top of lubrication fitting to bottom of ball

stud, and record the dimensions for each side.

3.
Then support vehicle weight at outer end of each

lower control arm, so that wheels or wheel hubs are

free,
then repeat Step 2.

4.
If the difference in dimensions on either side is

greater than 1/16" (.0625"), the joint is excessively

worn and both lower joints should be replaced.

If inspection of lower spherical joints does not indicate

excessive wear, inspect further as follows:

5.
On Chevrolet Only--Examine lubrication hole in each

joint assembly after cleaning out hole. Look for evi-

dence of the liner partially or fully blocking lubrica-

tion opening. Such evidence indicates that liner is

disintegrating and that both lower spherical joints

should be replaced.

Another indication of lower spherical joint excessive

wear is indicated when difficulty is experienced when

lubricating the joint. If the liner has worn to the point

where the lubrication grooves in the liner have worn

away, then abnormal pressure is required to force lubri-

cant through the joint. This is another reason to recom-

mend replacement of both lower joints.

If the above inspections do not indicate any reason for

spherical joint replacements, test the torque tightness of
Fig. 27 - Removing Lower Ball Joint - Chevelle
&
Camaro

the lower ball stud in the knuckle on each side as follows:

1.
Wire-brush off nut and cotter pin attaching spherical

joint ball stud to steering knuckle and examine for

evidence of looseness of stud in knuckle.

2.
If no evidence of looseness, remove cotter pin and

with prick punch or equivalent, mark nut stud and

knuckle to identify relative location.

3.
Tighten nut as installed and observe torque reading.

If less than 45 lbs. ft., stud may have been loose in

steering knuckle and replacement of both lower

spherical joints may be recommended.

4.
Check to see if torque of 60-94 lbs. ft. can be ob-

tained without bottoming stud or ball joint against

knuckle. If bottoming occurs, replace ball joint or

steering knuckle.

Chevrolet and Corvette

Removal

1.
Support lower control arm at outer end on floor jack,
