How Ball Joints Work
Ball joints are an important part of the vehicle suspension and steering system. Ball joints are a flexible ball and socket that allows suspension movement in more than one direction that enables positive control over the front wheels at all time. There are commonly upper and lower ball joints that connect each front wheel spindle to thecontrol arms. When driving a car through a turn, the ball joint allows the suspension arms to flex up and down over bumps while another ball joint connects the steering linkage to the steering knuckle on the spindle.
Ball joints are used to connect lower suspension control arm to the steering knuckle on the spindle. When turning, the suspension travels up and down and keeps constant control of the wheels. There are two types of ball joints, sealed units which don't require lubrication, and standard ball joints that require grease to be pumped into a zirk fitting.
When a ball joint becomes worn, they will have a measurable amount of play within the ball and socket. Each manufacturer has an acceptable limit before replacement is required. When driving a car over bumpy roads, the vehicle can jump one way or another after hitting a bump. Ball joints should be inspected regularly.
Common Problems
  • Premature failure is usually the result of poor maintenance.
