MooG® Problem Solver® k6696 upper Ball Joint

lack of induction hardening of entire ball stud

The upper ball joint for this vehicle fits a broad range of GVW, including ¾ ton. It is important that the replacement ball joint is designed to meet or exceed OE specification. The OE ball stud is induction hardened. Other suppliers may not induction harden the entire ball stud for this application. This may lead to stud fracture.

MOOG® Problem Solver® K6696 upper ball joint features a ball stud that is completely induction hardened – including the taper. This provides up to twice the strength of a part that is not entirely treated.In addition, this ball joint features other problem-solving technologies to give it longer service life and dependable operation:

MooG® Problem Solver® ball joints feature special installation aids

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.

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 ball joints with elliptical openings have a warning tag on the stud.
