How to Replace a Ball Joint

Ball joints are used to connect lower suspension control arm to the steering knuckle on the spindle. When turning your vehicle, the suspension travels up and down and still needs to keep constant control of the wheels, the ball joint allows the control arm to keep solid contact with minimal friction. There are two types of ball joints, sealed units which do not require any lubrication and standard ball joints that require grease to be pumped into the zirk fitting. Over time, sealed ball joints require less maintenance and tend to last longer, while standard ball joints if lubricated regularly can last just as long. When replacing a ball joint it can be proactive to replace the complete lower control arm.

Before you start park the car on level ground, in park with the emergency brake set. Wear protective clothing. gloves and eyewear.
