A sway bar, also known as an anti-roll bar, is a simple, yet crucial, device that reduces the amount of body roll, or lean, that a vehicle experiences during cornering. The sway bar is a thin, tubular piece of metal bolted to the suspension on each side of the car, either at the front or the back and often both. Some vehicles are only equipped with a front sway bar. A sway bar link connects the end of the bar to the suspension itself. These links can become broken or damaged, which will adversely affect the handling of the vehicle.
Poor or Unpredictable Handling
A broken or damaged sway bar link can cause your vehicle to handle poorly, particularly if the sway bar link is broken. If it is broken, then the sway bar is not connected to the chassis properly and will not prevent the car from leaning in a corner.
