available the following procedure may also be

used (fig. 22-Alternate Method).

1.
Support car on suitable hoist or jack (so control

arms may swing free) and remove the wheel and

tire assembly, shock absorber, and stabilizer link

at control arm.

2.
Place suitable jack stand under the lower control

arm cross shaft.

3.
Follow Steps 2-5 as outlined on previous page.

4.
Turn head of tool screw to partially compress

spring.

5. Remove the three control arm cross shaft attaching

bolts,
washers and nuts.

6. Carefully lower jack stand and if necessary increase

compression on spring and when coil spring is out of

its upper seat, relax tension on spring (fig. 22).

7. By using a pry bar to assist, if necessary, remove

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,

with hoist or jack pad clear of lower ball stud nut.

2.
Remove upper and lower ball stud nuts, free ball

studs from steering knuckle and wire knuckle and

interference while performing next step.

3.
Being careful not to enlarge the holes in control arm,

cut off rivets.

place with the attacking nut and install the cotter pin.
1.
With upper control arm support in position as in

Figure 15, disconnect the lower ball stud from steer-

ing knuckle.

2.
Assemble nut to lower ball stud and check rotating

torque with torque wrench. Specifications for new

joints are 9 lbs. ft. If torque readings are exces-

sively high or low, replace ball joint.

taining plate rivet heads. It may be necessary to

drill out rivet heads before chiseling.

NOTE: Additional support to lower control

arm will be necessary to perform this operation.

5.
Remove ball joint from arm and clean arm.

UPPER CONTROL ARM SPHERICAL JOINT

Chevrolet, Chevelle, Comoro and Corvette

Inspection

The upper spherical joint is checked for wear by

checking the torque required to rotate the ball stud in the

assembly. After performing the first four steps under

"Replacement" below, install a stud nut on the stud and

measure the torque required to turn the stud in the as-

sembly with a torque wrench. Specified torque for a new

joint is 9 lbs. ft. If torque readings are excessively

high or low, replace the ball joint. If excessive wear is

indicated in upper joint, both upper and lower joints

should be replaced.

NOTE:
This inspection does not necessitate

upper control arm removal.

Replacement

1.
Support the vehicle weight at the outer end of the

lower control arm.

2.
Remove the wheel and tire assembly.

3.
Remove cotter pin and nut from upper control arm

ball stud.

4.
Remove the stud from knuckle.

5. Cut off the ball joint rivets with a chisel.

6. Install new joint and retain in place with the special

nuts and bolts supplied.

7. Reassemble ball stud to the steering knuckle.

Chevy II

Inspection

The following on-the-vehicle check is to determine ball

joint wear.

NOTE:
The upper ball joint is a loose fit when

not connected to the steering knuckle. Wear may

be checked without disassembling the ball stud

by
using'
the following procedure:

1.
While vehicle weight is still on front wheels, insert

upper control arm support as shown in Figure 14.

2.
Raise vehicle and allow wheel and tire to hang free.

3.
Measure distance from tip of ball stud to top surface

of control arm.

4.
Place adjustable jackstand under tire and raise

slightly to take up ball joint looseness.

5. Repeat Step 3 and if the difference in measurements

exceeds 3/32", the joint is excessively worn and

should be replaced.

Replacement

1.
With vehicle weight still on front wheels, install

spacer between upper control arm and frame side

rail (fig. 15). Raise vehicle.

2.
Remove wheel and tire.

3.
Disconnect stabilizer link (if present) and strut rod

at lower control arm.

4.
Remove cotter pin and nut from upper ball joint stud.

5. Break ball stud loose. Drop lower control arm,

steering knuckle and brake assembly with an adjust-

able jackstand until upper control arm ball joint is

easily accessible.

6. Using a large chisel, cut off the three ball joint re-

taining plate rivet heads. It may be necessary to

drill out rivet heads before chiseling.

10—Toe-in Adjusting Shim Location (Corvette)

Toe-in

Wheel toe-in is adjusted by inserting shims of varying

thickness inside the frame side member on both sides

of the torque arm pivot bushing (fig. 10). Shims are

available in thicknesses of
1/64",
1/32",
1/8" and 1/4".

To adjust toe-in, remove torque arm pivot bolt; then

position torque arm to obtain specified toe-in. Shim gap

toward vehicle centerline between torque arm bushing

and frame side inner wall.

NOTE: Do not use thicker shim than necessary,

and do not use undue force when shimming inner

side of torque arm - to do so may cause toe

setting to change.

Shim outboard gap as necessary to obtain solid stack-

up between torque arm bushing and inner wall of frame

side member. After correct shim stack has been se-

lected, install pivot bolt and hardened washers (fig. 10) -
making sure that all shims are retained - torque nut to

specifications and install cotter pin. If specified torque

does not permit cotter pin insertion, tighten nut to next

SHOCK ABSORBER

Chevrolet and Chevelle

Removal

1.
Raise rear of vehicle and support rear axle

NOTE: When performing any service opera-

tions that requires removal or loosening of the

lower attaching nut, it is essential that the stud

be prevented from turning. A hex is located on

the stud between the axle bracket and shock

absorber in order that a wrench may be used

for this purpose. Failure to hold the stud in

this manner will result in damage to the mer

chanical bond between the shock absorber bush-

ing and the mounting stud.
