An axle assembly for a tractor is provided with a steering knuckle (24) and ball joint (40, 42, 46) assembly in which a ball stud (50) has a spherical ball portion (52) and a pair of studs (54, 56) extending oppositely therefrom for attachment to the steering knuckle (24). The double studded ball stud (50) enables the overall size of the ball studs (50) to be reduced compared to a ball stud (50) having a single stud and still accommodate the loads applied to the ball joint (40, 42, 46) by the dual front wheels (14). Ball joints (40, 42, 46) are used for both steering tie rods (44) and suspension control arms (26, 28). The steering knuckle (24) is pan shaped to surround the ball joints (40, 42, 46) on all but the interior side of the knuckle (24) where the steering and suspension arms (26, 28) are connected. This shielding of the ball joints (40, 42, 46) protect the ball joints (40, 42, 46) from dirt and debris, especially from the mud and dirt thrown by the front tires (14). <IMAGE> |
