The symptoms of a faulty sway bar are not always distinctive, and other issues may seem more likely. However, if you notice one or more of the following signs, it’s important to have the sway bar inspected:

Increased Body Roll: When turning, your vehicle may lean excessively on the outside wheels, rolling outward more than usual due to the sway bar's inability to balance the vehicle properly.
Tight Turn Radius: A diminished stability from a malfunctioning sway bar can result in an unusually tight turning radius while cornering.
Suspension Noises: Clunks and rattles are common indicators of a damaged or worn sway bar. Excessive play in sway bar bushings or end links can lead to metallic sounds.
Uneven Tire Wear: Abnormal tire wear is a strong sign of a sway bar issue, as it indicates that weight is disproportionately borne on the outer edge of the tire during turns.

Identifying these symptoms early can help you avoid more expensive repairs and get your vehicle back in optimal condition quickly.

Suspension sway bar FAQs

What does the sway bar do?

The sway bar, or anti-roll bar, is an essential part of a vehicle's suspension system that helps minimize body roll when cornering. It connects the left and right sides of the suspension, enabling them to stabilize the vehicle by transferring weight from one side to the other during turns. This action improves handling, stability, and overall driving comfort, particularly in sharp turns.

What factors contribute to a sway bar's failure?

A sway bar can become damaged due to normal wear and tear, corrosion from moisture and road salt, or impact damage from hitting potholes. Improper installation or excessive load on the suspension can also stress the sway bar, leading to failure. Regular inspections can help catch these issues early.

Is it safe to drive my vehicle with a faulty sway bar?

Driving a vehicle with a faulty sway bar is not safe. A damaged sway bar can compromise vehicle stability and handling, increasing the risk of losing control, especially during turns. It can also lead to uneven tire wear and further suspension issues.
