Control Arms

The control arm (also known as an A-arm) is a vital component of your Ford’s suspension system. It acts as a hinged link between the chassis and the suspension hub, which holds the wheel. The control arm manages your wheel’s vertical movement, allowing it to move smoothly over bumps, potholes, and uneven road surfaces. This helps keep your vehicle stable by maintaining proper wheel alignment and ensuring consistent contact with the road.

Signs Your Control Arm Might Be Failing

If your control arm starts to fail, it can significantly affect your vehicle’s handling, especially in emergency situations. Here are some common signs that your control arm may need attention:

  • Excessive steering wheel vibrations while driving.
  • The vehicle pulls to one side, wanders, or struggles to stay straight when cruising.
  • You hear clunking, knocking, popping, or squeaking noises when driving over bumps.
  • Uneven tire wear, with noticeable differences across the tread.

How Long Does a Control Arm Last?

Ford’s control arms are designed for durability, often lasting up to 150,000 miles under ideal conditions. On average, you can expect a lifespan between 90,000 to 100,000 miles. However, frequent driving over rough terrain or potholes can cause the suspension parts to wear out more quickly.
