摘要： A ball joint subject to wear in normal use and having fixed internal bearing seats in its housing for the ball stud unit giving rise to play or lash as the wear takes place has a manually operable wear indicator. The indicator is mounted on the housing cover in telescoping relationship with respect thereto and is manually operable to accumulate the play occasioned by the wear as a spacing between the ball stud unit and the fixed bearing seat on the cover. Indications are provided by the indicator and the cover cooperatively to identify to the operator whether wear justifying replacement does or does not exist. Wear justifying replacement is indicated when the indicator is manually movable to a position having a predetermined relationship with the cover which is sensible by the operator.
