Sway bar links connect the sway bar to the control arm. There is one link at each end of the arm.

Most modern vehicles have both a front and rear sway bar, as well as front and rear sway bar links.

How Does a Sway Bar End Link Work?

To understand how a sway bar end link works, you must be familiar with how it functions alongside other suspension components, especially the sway bar.

The sway bar helps manage the vehicle’s body roll by connecting the movement of two independent wheel assemblies. It provides more resistance to the inside tire while compressing the other side to reduce the vehicle’s body roll. This evens out the weight distribution of the vehicle and improves handling.

Although sway bars are typically made of long-lasting, durable steel, sway bar end links incorporate joints that can fail over time. This wear can introduce play that causes noises and affects the sway bar’s effectiveness.

What Happens if a Sway Bar End Link Breaks?

If one of your vehicle’s sway bar end links break, the other one won’t be too far behind. This will often result in strange noises coming from your vehicle and possibly a decrease in handling performance.

A sway bar link can become misaligned, bent, or corroded due to impact damage, excessive load, or regular wear and tear.

Can You Drive With a Broken Sway Bar End Link?

Yes, but doing so can make your vehicle noisy and possibly lead to a reduction in handling performance. So, it’s a good idea to replace a bad sway bar end link as soon as possible.

When Should Sway Bar End Links Be Replaced?

How Can Bad Sway Bar Links Cause Excessive or Uneven Tire Wear?

A faulty sway bar link can impact your vehicle’s weight distribution. This causes some tires to get more weight than others, resulting in premature tire wear.

A faulty sway bar link could increase body roll, which is the side-to-side leaning movement during turns. This puts more stress on the tires, particularly their outer edges.

Do Bad Sway Bar Links Cause Wheel Vibration?

The sway bar transfers loads between suspension components, but the vibrations could travel up the steering system if there’s something wrong with the links.
