Do the job with confidence, replace your worn components with the leader in performance ball joints: Proforged. 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 han dling 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.
