OEM BMW Control Arms & Parts

The control arms are essential components in your BMW vehicle's suspension system. They're the direct connection between your chassis and the front wheel assemblies. One ed of the control arm connects to the chassis, where bushings help to prevent metal-on-metal contact and limit vibration and noise. The other control arm end connects to a steering knuckle via a ball joint. That allows for smooth movement in every direction.

Types of Control Arm Assemblies

There are three: bolt in, unitized, and press in. MacPherson struts usually have bolt-in assemblies. Both unitized and press in assembled integrate with a ball joint, meaning that you need to replace the entire assembly when you're changing out a bad one. That's typically easier than replacing a bolt in assembly type.

When a control arm fails, it usually does so in gradual stages. Driving with a bad control arm isn't safe, so you need to know when yours is beginning to fail.

How to Spot a Failing Control Arm

Signs include:

• Vibrating wheels
• The steering wheel wanders
• Your ride comfort worsens
• You notice strange noises
• Uneven tire wear
• Inconsistent brakes performance
