Abstract
A method of determining seal failure is implemented in a ball joint including a stud having a ball embedded in grease within a sealed socket assembly. A dielectric characteristic of the grease is measured to determined if the sealed socket assembly has failed based upon a substantial variation of the measured dielectric characteristic from a predetermined value.
