What are Sway Bars?

034 Bar

A sway bar is a solid or hollow bar that's connected to the lower suspension arms on each side, as well as the body or frame. Some Audis come with one sway bar, but most come with two sway bars (one in the front, one in the rear). The point of having sway bars on your Audi is to stabilize your car, increase traction, and reduce body roll when your car corners. It's a pretty important component for high performance driving.

For a thorough explanation of sway bars and how upgrading your sway bar can do wonders for your Audi's performance, check out this article.

How to Know if Your Sway Bar Has Gone Bad

The sway bar itself rarely fails because it's just a bar. However, the mounts and links will wear out over time because they're moving parts. If something on your sway bar goes bad, you'll notice some symptoms, including:

  • Rattling, clunking, or unusual noises while driving over bumps or turning corners
  • Poor handling during turns
  • Loose feeling in the steering wheel

The best way to formally diagnose a malfunctioning sway bar is to visually inspect it. This sway bar diagnostic guide has all the steps you need to follow to thoroughly examine your sway bars and identify issues.

OEM Vs. Aftermarket Sway Bars

If you use your Audi for performance driving, you definitely want to look into upgrading to aftermarket sway bars. OEM sway bars are designed for every day driving, not performance driving. If you upgrade to better sway bars on your Audi, you'll notice a lot less body roll through corners and more precise steering.

How to Install a Sway Bar

Replacing a sway bar sounds challenging, but it's actually quite easy. In fact, you would just need a jack, jack stands, and basic hand tools to tackle this job. The process basically involves lifting your car, removing the tires, removing the old sway bar, and then installing the new sway bar. There are model-specific tutorials around the web, including this one we put together for Audi A4s.
