The folding top adjustments are:

Header (View A, Fig. 101)

Header assembly may be moved fore and aft when the

two clamping screws are loosened. This will correct such

conditions as header latch guide pin alignment with the

holes in the windshield upper frame. Symptoms of mis-

alignment are such conditions as loose top trim when

top is up and locked, and excessive effort required to

engage header locks. Note that it will be necessary to

remove side roof rail weatherstrip to gain access to

header outer clamping screw. Refer to Weatherstrip

portion of this section.

Hinge (View B, Fig. 101)

The hinges may be moved up and down and fore and aft

to the limit of the slotted holes in hinge plate and body.

To gain access to hinge, remove rigid plastic trim as

explained in Interior Trim portion of this section. Re-

positioning hinge will correct conditions such as poor top

fit at upper and rear edge of windows; faulty fore and aft

engagements of rear bow hold-down pins in lock assem-

blies and loose or oversight top rear panel when top is

raised and properly locked in position.

Rear Bow Hold-Down Locks (View C, Fig. 101)

The hold-down pins may be moved to left or right to
center top on body in raised position; thus correcting

poor alignment at windows and difficult entry of pins

in locks.

TOP ASSEMBLY REMOVAL AND INSTALLATION

The entire top assembly (frame with trim attached)

may be removed from vehicle as follows:

1.
Raise top, but do not engage header or rear bow

locks.

2.
Remove rigid plastic trim as outlined in Interior

Trim portion of this section.

3.
Mark installed position of hinge by scribing outline

of hinge plate on lock pillar surface.

4.
Remove two screws retaining each hinge to lock

pillar and remove top assembly from vehicle.

MAINTENANCE AND ADJUSTMENTS

Maintenance intervals recommended for lubrication of

front suspension components have been fully covered in

Section 0 of this manual. Only actual adjustment proce-

dures will be covered here.

NOTE:
Unless otherwise indicated all proce-

dures will apply to all five vehicles covered in

this manual.

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
be.
repacked

or adjusted as a part of "New Car Conditioning".
1.
With wheel raised, remove hub cap and dust cap and

then remove the cotter pin from the end of the

spindle.

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

.001"
to .008" end movement when properly ad-

justed on Chevrolet, Chevelle, Camaro and Cor-

vette; .000" to .004" on Chevy H.

5.
Install dust cap, hub cap or wheel disc and lower

wheel.

6. Perform the same operation on each front wheel.

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).

CHEVROLET CHASSIS SERVICE MANUAL

FRONT SUSPENSION 3-6

Fig.
8 - Caster and Camber Adjustments - Chevy

To adjust for caster and camber, loosen the upper sup-

port shaft to crossmember nuts, add or subtract shims as

required and retighten nuts.

NOTE:
Caster and camber can be adjusted in

one operation.

Caster and camber specifications will be found in the

last section of this book.

Chevrolet and Chevy II

The caster angle is adjusted by turning the two niits at

the front of the lower control arm strut rod (figs. 7 and

8).
Shortening this rod will increase caster. Lengthen-

ing will decrease caster.

Camber angle is adjusted by loosening the lower con-

trol arm pivot bolt and rotating the cam located on this

pivot. This eccentric cam action will move lower control

arm in or out, thereby varying camber.

Steering Axis Inclination Adjustment

"Camber" is the outward tilt of the wheel and "steering

axis inclination" is the inward tilt of the knuckle. Cam-

ber cannot be changed without changing steering axis

inclination. Correct specifications willbe found at the

end of this section. If, with the camber correctly ad-

justed, the steering axis inclination does not fall within

the specified limits the knuckle is bent and should be

replaced.

If a new knuckle is installed, caster, camber and toe-in

must be readjusted.

Toe-In Adjustment

Toe-in, the inward pointing of both front wheels, is

checked with the wheels in the straight ahead position. It

is the difference of the distance measured between the

extreme front and the distance measured between the ex-

treme rear of both front wheels. Correct toe-in specifi-

cations will be found at the end of this section.
NOTE:
Toe-in must be adjusted after caster

and camber adjustment.

A. If the equipment being used measures the toe-in of

each wheel individually:

1.
Set the steering gear on the high point, mark 12

o'clock position on the steering shaft and position

the steering wheel for straight ahead driving.

2.
Loosen the clamp bolt at each end of each tie rod

and adjust to the total toe-in as given in the speci-

fications at the end of this book.

B.
If a tram gauge is being used, proceed as follows:

1.
Set the front wheels in the straight ahead position.

2.
Loosen the clamp bolts on one tie rod and adjust

for the proper toe-in as given in the specifications

at the end of this book.

3.
Loosen the clamp bolts on the other tie rod. Turn

both rods the same amount and in the same direc-

tion to place the steering gear on its high point and

position the steering wheel in its straight ahead

position.

C.
After the adjustment has been made:

1.
a. Chevrolet—Position inner tie rod clamp bosses

forward to 90° down to avoid stabilizer link bolt

interference.

b.
Chevelle—Position the tie rod clamp bosses

down to 45?° forward to avoid interference.

c. Chevy II--Position the outer tie rod clamp

bosses forward and not more than 45° up or

down from horizontal to avoid interference.

Inner clamps forward and vertical.

d. Corvette--Position inner tie rod clamps with

bolt horizontal and down. Position outer clamps

with bolt vertical and to the rear.

e. Camaro—Position inner tie rod clamps with

open end of clamp and slot in line. Position

relative to ground unimportant. Position outer

clamps with bolt top and 30° either side of ver-

tical. Position relative to slot unimportant.
