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.

Removal

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.

or other evidence of fatigue. If cracks are present at

the rivet holes or ball joint opening, replace arm as

outlined later in this section.

8. Attach replacement ball joint assembly to the control

arm, using special bolts furnished with replacement

kit.

NOTE:
Use only special hardened bolts fur-

nished with this replacement kit. Do not attempt

to use other non-hardened bolts and do not at-

tempt to rivet replacement ball joint to arm.
9. Raise lower control arm and steering knuckle as-

sembly into position, insert upper ball stud into up-

per steering knuckle and install stud nut. Torque

nut as shown in the specifications and insert new

cotter pin. Install stabilizer and strut rod.

Lubricate ball joint, install wheel and tire and re-

move adjustable jackstand.

11.
Lower vehicle and remove upper control arm spacer.

12.

necessary.

LUBE FITTINGS

Special self threading type lube fittings are used in the

spherical joint assemblies. If it is necessary to replace

a fitting a standard threaded type may be used. However,

replacement spherical joint assemblies are supplied less

the lube fitting. Therefore it will be necessary to install

a self threading type fitting into the untapped hole pro-

vided when replacing the entire assembly.
