A ball joint is basically a spherical bearing. It lets the control arm pivot and move up and down while still allowing the wheel to steer. Think of it like your shoulder joint – it allows a lot of movement in different directions, but still keeps everything connected. It's a pretty simple idea, but crucial for how your car handles. It connects the control arm to the steering knuckle – that’s the part that holds the wheel hub and brake components. So, every time you hit a bump, steer, or brake, these joints are working. They allow the suspension to move with the road while keeping the tires pointed in the right direction. It’s a key component in your front suspension system, helping with steering and ride quality. If a ball joint wears out, you’ll notice it. You’ll usually start hearing a clunking noise, especially when going over bumps or turning the wheel. If it gets really bad, you can get loose steering or even have the wheel separate from the suspension, which is obviously dangerous. It acts like a shield protecting the other more expensive parts of your suspension from serious impact. Replacing them when they get worn is a much cheaper fix than dealing with the damage if you ignore it. We stock a lot of different ones – you can often find what you need quickly at places like Fixparts Online, but we can definitely help you find the right one for your car here too.
