A ball joint is a type of joint that allows for rotation in all directions. It is commonly used in automotive suspension systems, connecting the control arm to the steering knuckle. Checking ball joints is important for ensuring the safety and performance of your vehicle.
There are a few different ways to check ball joints. One method is to look for signs of wear or damage. This can include cracks, rust, or excessive play in the joint. Another method is to use a pry bar to try to move the ball joint. If the joint moves easily, it may be worn or damaged.
