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
