PROBLEM : Improper installation alignment can lead to early component failure Press-in ball joints on some late-model vehicles are now designed with an elliptical stud opening. Failure to properly align the ball joint in the control arm during installation could result in loss of vehicle control due to ball joint failure. If an elliptical joint is pressed into the control arm without regard to orientation, it is possible that normal vertical suspension movement will cause the ball joint stud to contact the housing, resulting in stud and/or housing failure. Elliptical openings are not visible on ball joints with preinstalled boots.
SOLUTION : MOOG® ball joints feature special installation aids Always look at press-in ball joints for alignment marks such as drilled holes, arrows, punch marks, etc., and follow instructions regarding orientation when installing the joint in the arm. MOOG instruction sheets contain specific information about ball joint orientation where applicable. In addition, MOOG-manufactured ball joints with elliptical openings have a warning tag on the stud.
