A STEERING KNUCKLE AND BALL JOINT ASSEMBLY FOR TRACTOR FRONT AXLE

Abstract A steering knuckle and ball joint assembly for a tractor is provided in which the ball stud has a spherical ball portion and a pair of studs extending oppositely therefrom for attachment to the steering knuckle. The double studded ball stud enables the overall size of the ball studs to be reduced compared to a ball stud havingb a singla stud and still accommodate the loads applied to the ball joint by the duall front wheels. Ball joints are used for both steering tie rods and suspension control arms. The steering knuckle is pan shapped to surround the ball joints on all but the interior side of the knuckle where the steering and suspension arms are connected. This shielding of the ball joints protect the ball joints from dirt and debris,especially from the mud and dirt thrown by the front tires.
