An anti-roll bar, commonly referred to as a sway bar or stabiliser bar, is an essential part of your car’s suspension system. Usually, it’s a metal rod that connects the left and right wheels of the vehicle. Its main job is to reduce body roll when cornering and enhance overall stability.

How does it work? When your car turns, the weight shifts to one side, causing the vehicle’s body to roll or lean towards that direction. The anti-roll bar works against this movement by transferring some of the suspension movement from one side of your car to the other. As a result, your tyres maintain better contact with the road and provide improved traction and handling.

Buying the correct anti-roll bar for your car is simple with our lookup tool. Just enter your vehicle registration, and we’ll provide suitable car parts for your pride and joy. Alternatively, you could head to your local Halfords store, where one of our friendly colleagues will happily lend a hand.

Faulty Anti-Roll Bar symptoms

A faulty anti-roll bar can be a serious safety hazard, as it can affect the handling and stability of your vehicle. These are the common symptoms to watch out for:

  • Excessive body roll: An anti-roll bar reduces body roll when you turn. So, if you have a faulty anti-roll bar, you may spot more swaying or leaning when you corner.
  • Poor handling and stability: A faulty anti-roll bar can make your vehicle less stable on the roads, particularly during sharp turns or sudden manoeuvres.
  • Rattling noises: Worn-out or damaged bushing, links, or mounts on the anti-roll bar can cause clunking or rattling sounds, especially when driving over bumps or uneven surfaces.
  • Uneven tyre wear: A faulty anti-roll bar can lead to uneven tyre wear, which, in turn, can cause early wear on one side of your car.
  • Pulling to one side: If your vehicle’s anti-roll bar isn’t working correctly, it may cause your car to pull to one side.
  • Excessive body movement: As well as increased body roll, a faulty anti-roll bar can cause excessive body movement and make your ride less comfortable and controlled.
  • Dashboard warning lights: Many modern cars have stability control systems to alert you if there are issues with the anti-roll bar. If there’s a problem, you should see an icon on the dashboard warning light.

How often should you replace your anti-roll bar?

The average anti-roll bar typically lasts for at least 50,000 miles. But sometimes, they can wear due to stress and harsh driving conditions, such as driving on uneven or rugged terrain.

Other Suspension and Steering Car Parts:

Wheel Bearings and Wheel Hubs:

Wheel bearings allow your wheels to rotate smoothly. They’re located within the wheel hub assembly, providing support and reducing friction as the wheels turn.

Car Suspension Arms and Joints:

Car suspension arms and joints connect your car’s frame to the wheels. Positioned in the suspension system, they absorb shocks and vibrations for more stable and comfortable driving.

Car Springs:

Found between the vehicle’s frame and wheels, car springs dampen and absorb shocks on uneven surfaces. This improves comfort and reduces wear and tear on other suspension components.

Suspension and Steering:

Your suspension and steering systems work together. The steering system connects to the suspension system through the steering column and pivot joints, while the suspension system includes components that absorb shock and vibrations for road comfort and control.

Anti Roll Bar FAQs

You can drive without an anti-roll bar. But bear in mind that handling your vehicle may be more challenging, and you could have issues such as reduced traction, discomfort, uneven tyre wear and increased body roll.

Road conditions cause the most damage. For example, falling into a pothole can cause damage to your anti-roll bar.

How much you pay for an anti-roll bar depends on the manufacturer and model of your vehicle. Find the right one for your vehicle by using our handy lookup tool.

The main difference between an anti-roll bar and an anti-roll bar link lies in their functions and what they connect. An anti-roll bar is the structural component that resists body roll, while the anti-roll bar is the connecting link that transmits the forces from the wheels to the anti-roll bar.

Commonly referred to as a sway bar or stabiliser bar, an anti-roll bar is a metal rod that connects the left and right sides of your vehicle’s suspension. It enhances stability and handling by reducing body roll and swaying when you corner.
