The front upper ball joint connects the upper suspension arm to the steering knuckle, allowing controlled articulation while maintaining precise wheel alignment geometry. On the Discovery, worn or seized ball joints produce clunking noises over rough terrain, increased steering play, and uneven tyre wear. Replacing this component with a correctly specified unit is essential to restoring steering accuracy and preventing accelerated wear on adjacent suspension components.
