14. Front Suspension Spherical
Joint Checking Procedure
If the spherical joints show signs of looseness
or wear, they may be checked by the following
procedure after first disconnecting the ball stud
from the steering knuckle.
a. Upper Spherical Joint
Using the regular spherical joint stud nut and a
second nut as a locknut, turn joint in its socket
with a torque wrench. It should read 2-4 foot-
pounds. Replace a joint that is too loose or too
tight.
b. Lower Spherical Joint
The lower spherical joint is designed to turn
freely in its socket and cannot be checked with a
torque wrench. It should be checked by noting the
amount of free play as the joint is worked verti-
cally in its socket. Free play should not exceed
1/16 inch. Replace joint if it exceeds this limit.
NOTE: If joints are to be cleaned, use a
clean cloth only. Do not use solvent.

a. Removal
1. Raise front end of car, place jack stands
under lower suspension arms and remove wheel.
2. Remove lock nut and special flat washer
from upper spherical joint stud.
3. Remove joint from knuckle using a 7/16 inch
steel rod approximately 20 inches long, rounded

Then, using a heavy hammer, strike end of rod

4. Remove lock nuts and shaft mounting bolts
at frame tower, Fig. 4-32, and remove upper sus-
pension arm and shaft assembly.
