- WHAT IS A BALL JOINT? A ball joint is an enclosed spherical bearing that connects the control arm to the steering knuckle or spindle - it is a ball-and-socket design， just like your hip， and it needs to be replaced as it wears out. A worn ball joint causes poor handling and makes it difficult or impossible to achieve an alignment， which leads to rapid tire wear. Replacing your worn ball joints gives a noticeable improvement in steering feel， handling， and safety.
