As a front lower ball joint, it locates the steering knuckle and lets the suspension pivot as the wheel steers and travels. Signs it may need replacing include clunking on acceleration or over bumps, wandering steering, or uneven tire wear — diagnose the cause before replacing. Replacing the joints on both sides together is recommended. See the "Vehicles it fits" section for the full engine-level fitment.
