Anti-roll bar links are short metal rods with joints known as 'bushings' at each end. The purpose of anti roll bar links is to connect the anti-roll bar in a car's suspension to the rest of the suspension structure. Anti-roll bars are fitted to just about any car these days. Most cars have an anti-roll bar on the front as well as the rear of the car. Anti-roll bars stabilize your car when you go through a corner. Whilst it is an important component it's often tricky to know whether you will need to replace it. Luckily there are a couple of checks that can be done to find out if it needs replacing.
