Your car’s suspension is an integral part of driving, the ball joints are an integral part of your suspension system. They make sure that while your car goes over bumps, it can also turn. They’re an important part of your car and they’re something worth taking good care of.

What is a ball joint? 

Believe it or not, it’s a joint that comes in the form of a sphere - a ball if you will. The ‘ball’ is fitted to a socket. The two parts are then protected from damaging each other with a teflon coating to stop them rubbing against each other. They are also lubricated and sealed with a synthetic bushing. This allows them to shift and rotate freely, allowing the vehicle to turn and corners very stably.
