While there are some differences in how different manufacturers put together automobiles, some parts are universal. The ball joint is one of those universal parts; you find it on virtually every automobile in existence, from classic early vehicles to concept cars. Ball joints work much like the human hip joint. The joints, themselves, are a bearing stud and socket enclosed in a casing. The bearing stud, which is tapered and threated, fits into a hole in the steering knuckle. This connects the control arm to the steering knuckle. The joint is usually encased in some type of protective outer covering, usually a rubber-like boot, which keeps dirt from getting into the assembly and allows the lubricant to expand and contract with heat and movement.
