The Audi A4 control arm is an important part of your car's suspension system. There are two A4 control arms at each wheel, an upper and a lower. There are several functions performed by the Audi A4 control arm.

As part of your suspension system, the A4 control arm assists in handling and control. The Audi A4 control arm also helps keep your wheels aligned, and allows your tires to give when you pass over bumps, which keeps your ride smooth.

Each A4 control arm contains pivot points that are covered with rubber bushings to prevent friction as the Audi A4 control arm moves against other suspension components. Damage to your A4 control arm is often detected through a drop in handling and ride performance. You may also hear noises from your front end if there are problems with an Audi A4 control arm, particularly when going over bumps. The most common trouble concerning the A4 controls arms occurs when the rubber bushings deteriorate over time or due to exposure to the elements. Road salt often has a corrosive effect on rubber. The Audi A4 control arm may also become bent if you hit an especially hard bump or pothole, which causes uneven suspension or excessive bouncing during normal driving. A4 control arms allow your wheels to move back into their proper positions, and a bent Audi A4 control arm will impede this process.
