Lower Ball Joint (Single Arm)

With vehicle resting on normal driving surface, wipe ball joint grease fitting and checking surface free of all grease or dirt. The round boss into which the grease fitting is threaded (checking surface) should extend outside the ball joint cover. If round boss is inside cover, replace lower control arm assembly. Similar to Figure. Ball joints and lower control arm bushings are not serviced separately. Replace entire control arm, bushing and ball joint assembly. Ball joint seals may be replaced, however.
