Maintenance & Troubleshooting

Signs of Wear & Troubleshooting

  • Signs of wear for control arms include but are not limited:
    • Unexpected noises: popping or creaking noises in the suspension system, or a clunking noise when driving over a bump or pothole.
    • Difficulty steering: extra play in the steering system, or wobbling in the steering wheel when driving at high speeds.
    • Vehicle wandering: if your vehicle pulls to one side while driving, it may indicate the need to replace your control arms.
    • Abnormal or uneven tire wear: this may be a sign of control arm wear.
    • Alignment issues: an inability to set the proper alignment for your vehicle may indicate control arm wear.

Good Maintenance Practices

  • Inspect or have your control arms inspected for signs of wear. Exposure to harsh driving conditions, like potholes or bumpy road surfaces, can place stress on your vehicle's control arms. Over time these stresses can cause the bushings of your control arms to wear out or loosen, possibly causing excessive tire wear, noise in the suspension system, or extra play in the steering system. Accidents may also result in bent control arms, hindering your handling capabilities. Inspect your control arms regularly, following exposure to events that may harm the component, or when you experience signs of control arm wear.
  • Installing a new control arm affects the alignment of your vehicle. It is necessary to perform a front wheel alignment after any control arm replacement.
