Re: Anyone Seen these on a Car?
Rick,
The "button" nests in the impression in the end of the spindle, and the sharp points make contact with the inside of the grease cap. As the hub rotates around the splindle it creates static interference in the air which is not grounded away very well due to the grease on the bearings. The grease cap transfers this static charge through the brass suppressors to the spindle, which is grounded to the chassis. All cars with factory installed radios since the late '50s had these installed. They were usually tossed the first time the front bearings were serviced.
