The steering ball joint for the Coleman AT200-B ATV uses the M12x1.25 threaded stud, and the longer 5/8-18 threaded a-arm stud. The ball joint includes the rubber boot, a grease zerk, an M12x1.25 castle nut, a 5/8-18 nut, and a lock nut for the stud. The use of metric and ASI thread on the same ball joint is not unusual.
Ball joints are vital to your steering system and should always be replaced when worn.
