OEM Audi Control Arms Online

Control arms, also known as "A arms," are important parts of the front suspension on your Audi car or SUV. They connect the frame or body to the wheel assembly. Some models have two control arms, while others have four—two upper and two lower.

One end of a control arm connects to the chassis, where bushings limit vibration and noise while reducing any metal-on-metal contact. The other end connects to the steering knuckle by way of a ball joint. That allows your wheels to enjoy smooth movement in every direction.

Types of Control Arm Assemblies

Control arms are connected through bolt in, unitized, or press in assemblies. MacPherson struts typically features bolt-in assemblies. Unitized and press in assemblies both integrate with a ball joint, so you'll need to replace the whole assembly when you're replacing one. That's usually an easier job than it is to replace a bolt-in assembly.

How to Recognize Failing Control Arms

Even the best control arms can wind up going bad, whether due to age or rough road conditions. Signs of problems include:

• Loss of control
• Your Audi drifts when you brake or go over uneven terrain
• Uncomfortable ride quality
• Popping or clunking sounds
• Uneven tire tread wear
